Biostratigraphical value of some Strunian (Devonian, uppermost Famennian) Productidina, Rhynchonellida, Spiriferida, Spiriferinida brachiopods

The space of Devonian time considered in this paper corresponds to the uppermost part of the Famennian or the latest Famennian as a fourfold subdivision of the stage, usually called by many authors Strunian in neritic facies and Wocklumeria Stufe or Wocklumian in pelagic facies. Here, we examine the biostratigraphical value of certain brachiopod genera and species as bio-markers of the uppermost Famennian throughout the world (Europe, the former USSR, Middle East, Asia, North America, North Africa, and Australia). We have focused our study for species which stratigraphical range has been firmly established in correlation with the conodont biozones (Upper expansa, Early, Middle and Late praesulcata), the ammonoid biozones (do VI = “Wocklumeria Stufe”), or the foraminifera biozones (kobeitusana Zone). Other data for which the stratigraphical range is not based on standard biozonation are provided in the annex. The brachiopod bio-markers discussed in this paper belong to 14 Productidina genera (Acanthatia, Araksalosia, Ericiata, Hamlingella, Mesoplica, Nigerinoplica, Orbinaria, Ovatia, Rugauris, Semiproductus, Sentosia, Spinocarinifera, Steinhagella, Whidbornella), 7 Rhynchonellida genera (Araratella, Centrorhynchus, Hadyrhyncha, Megalopterorhynchus, Novaplatirostrum, Rozmanaria, Tchanakhtchirostrum), 13 Spiriferida genera (Brachythyris, Cyrtospirifer, Dichospirifer, Eochoristites, Imbrexia, Parallelora, Prospira, Rigauxia, Sphenospira, Tenisia, Toryniferella, Tylothyris, Voiseyella) and one Spiriferinida genus (Syringothyris). Other orders have not been studied in this paper. The main features of the uppermost Famennian brachiopod taxa represented in this paper are commented. All these taxa are listed as completely as possible throughout the world (with complements in the annex). A quick summary of the geographic distribution of the more represented taxa is given in conclusion.     

Morphogenesis and evolution of Kutorgina Billings, 1861 (Brachiopoda, Kutorginida)

A comparative morphological analysis of all known members of the Lower-Middle Cambrian genus Kutorgina, one of the brachiopod genera with a carbonate shell that are oldest and richest in species. The evolution of the genus is discussed, and the borders between the Kutorgina species are emended. A new species, Kutorgina elanica sp. nov., is described.     

Early Carboniferous spiriferoid brachiopods from the Qaidam Basin,Northwest China: Taxonomy,biostratigraphy and biogeography

Six Early Carboniferous brachiopod species in four genera of the Superfamily Spiriferoidea are described from the Qaidam Basin, northwestern China, including a new genus, Qaidamospirifer, and two new species: Grandispirifer qaidamensis and Qaidamospirifer elongatus. Additionally, a new genus, Triangulospirifer, is also proposed to replace Triangularia Poletaev, 2001 that was preoccupied by a Devonian molluscan genus.On the basis of the new material as well as published information, we have reviewed the taxonomic composition and the stratigraphic and palaeobiogeographic distributions of the three previously established genera from the viewpoint of palaeobiogeography. The study reveals that Grandispirifer has a relatively long stratigraphic range from the late Tournaisian to Serpukhovian. During this interval, the genus attained a wide geographical distribution, reaching Northwest China, western Yunnan of West China, Japan, as well as Iran and North Africa. Angiospirifer first occurred in western Europe in the Viséan, and later migrated to North Africa during the late Viséan. In the Serpukhovian, it migrated eastward, reaching the Donets Basin of Ukraine and the Qaidam Basin in Northwest China. Anthracothyrina evolved from Brachythyrina in North Africa in late Viséan, then dispersed north-westward to western and eastern Europe and, further eastward to the Qaidam Basin during the Serpukhovian.     

Gastropod mollusks from the Hauterivian of Ulyanovsk (Volga Region): 2. Genera Khetella Beisel, 1977 and Cretadmete gen. nov.

The diagnosis of the genus Khetella Beisel, 1977 is emended, and a new genus, Cretadmete, is described. Two new species belonging to these genera, K. trautscholdi and C. neglecta, are established from the Upper Hauterivian of Ulyanovsk (Volga Region).     

GENERIC HOMES FOR BRITISH SILURIAN LINGULOID BRACHIOPODS

Abstract: Since the brachiopod Order Lingulida has been greatly revised in recent years, with particular emphasis on Cambrian and Ordovician genera, many well‐established Silurian linguloid species from the British Isles have been left without an appropriate genus in which to place them. This is rectified here by allocating the various species, mostly erected in the nineteenth or early twentieth centuries, to a variety of genera which have been mainly erected within the last forty years. Two new genera are erected, Mergliella, with type species Lingula bechei Davidson, 1866 , and Striatilingula, with type species Lingula? striata J. de C. Sowerby, 1839 .     

A new delthyridoid spiriferid genus from the Dra Valley, Morocco, and its phylogenetic affinities (Brachiopoda, Lower Devonian)

Multiplicatispirifer, a new delthyridoid brachiopod genus with a gently divergent capillate micro-ornamentation and bifurcating costae on flanks, sulcus and fold, has been identified in the Mdâouer-el-Kbîr Formation of the Dra Valley (southern Anti-Atlas, Morocco). Its type speciesMultiplicatispirifer foumzguidensis n. gen., n. sp., at present the only species of this genus, is described. This form has hitherto been determined asFimbrispirifer orStruveina by various authors. In this work, the new genus is compared with the multiplicate and capillate spiriferid genera with bifurcating costae which also have costae in the sulcus and on the fold:Costispirifer andPerryspirifer from North America,Elymospirifer from South China,Borealispirifer from Asia andMultispirifer from Central Europe. The relation ofMultiplicatispirifer to the fimbriateFimbrispirifer, Struveina andVandercammenina, from which it is distinguished by its capillate micro-ornamentation, is discussed. The new genus is hitherto only known from the Moroccan southern Anti-Atlas. Its colsest relatives, taxa ofCostispirifer, occur in the Eastern American Realm (Gaspé, Canada and the eastern United States) and the Nevada Province (western United States).Multiplicatispirifer occurrences are restricted to the Lower/Upper Emsian boundary interval (upper Lower Devonian). The reasons for a possible migration corridor between North America and North Africa before Emsian time are discussed.     

The brachiopod family Linoproductidae stehli from the lower Moscovian of the Middle Carboniferous of the Moscow Region

The phylogeny and taxonomy of the brachiopod family Linoproductidae are revised. The change in the distributional pattern of spines and distinctive structure of the median lobe of the cardinal process are shown to be the main apomorphies in the family evolution. A new subfamily, Linispininae, and the included new genera, Linispinella and Linispinus, are described. In the nominotypical subfamily Linoproductinae, a new genus Linoproductoides and two new species included in this genus are described from the Vereiskian deposits of the Moscow Region. The new species Linispinus riparius (Trautschold), L. longus sp. nov., and L. staricensis (Ivanov) are described from the Kashirskian deposits. Another new species is tentatively described as “Linoproductus” kabanovi.     

Phylogenetic relationships of phrynosomatid lizards based on nuclear and mitochondrial data,and a revised phylogeny for Sceloporus

Phrynosomatid lizards are among the most common and diverse groups of reptiles in western North America, Mexico, and Central America. Phrynosomatidae includes 136 species in 10 genera. Phrynosomatids are used as model systems in many research programs in evolution and ecology, and much of this research has been undertaken in a comparative phylogenetic framework. However, relationships among many phrynosomatid genera are poorly supported and in conflict between recent studies. Further, previous studies based on mitochondrial DNA sequences suggested that the most species-rich genus (Sceloporus) is possibly paraphyletic with respect to as many as four other genera (Petrosaurus, Sator, Urosaurus, and Uta). Here, we collect new sequence data from five nuclear genes and combine them with published data from one additional nuclear gene and five mitochondrial gene regions. We compare trees from nuclear and mitochondrial data from 37 phrynosomatid taxa, including a “species tree” (from BEST) for the nuclear data. We also present a phylogeny for 122 phrynosomatid species based on maximum likelihood analysis of the combined data, which provides a strongly-supported hypothesis for relationships among most phrynosomatid genera and includes most phrynosomatid species. Our results strongly support the monophyly of Sceloporus (including Sator) and many of the relationships within it. We present a new classification for phrynosomatid lizards and the genus Sceloporus, and offer a new tree with branch lengths for use in comparative studies.     

Global Diversity and Phylogeny of Pelagic Shrimps of the Former Genera Sergestes and Sergia (Crustacea,Dendrobranchiata, Sergestidae), with Definition of Eight New Genera

We revise the global diversity of the former genera Sergia and Sergestes which include 71 valid species. The revision is based on examination of more than 37,000 specimens from collections in the Natural History Museum of Denmark and the Museum of Natural History, Paris. We used 72 morphological characters (61 binary, 11 multistate) and Sicyonella antennata as an outgroup for cladistic analysis. There is no support for the genera Sergia and Sergestes as they have been defined until now. We define and diagnose eight genera of the former genus Sergia (Sergia and new genera Gardinerosergia, Phorcosergia, Prehensilosergia, Robustosergia, Scintillosergia, Challengerosergia, and Lucensosergia) and seven genera of the former genus Sergestes (Sergestes, Deosergestes, Eusergestes, Allosergestes, Parasergestes, Neosergestes, and a new genus Cornutosergestes). An identification key is presented for all genera of the family Sergestidae. The phylogeny of Sergestidae is mainly based on three categories of characters related to: (1) general decapod morphology, (2) male copulatory organs, and (3) photophores. Only simultaneous use of all three character types resulted in a resolved tree with minimal Bootstrap support 75 for each clade. Most genera are interzonal mesopelagic migrants, some are benthopelagic (Scintillosergia, Lucensosergia), bathypelagic (Sergia), or epipelagic (Cornutosergestes). Within each of meso- and benthopelagic genera there is one species with panoceanic distribution, while most species ranges are restricted to a single ocean. The genera demonstrate two different strategies expressed both in morphology and behavior: protective (Eusergestes, Sergestes, Cornutosergestes, Prehensilosergia, Scintillosergia, Lucensosergia, Challengerosergia, Gardinerosergia, Robustosergia, Phorcosergia, Sergia) and offensive (Neosergestes, Parasergestes, Allosergestes, Deosergestes).     

Early Devonian (Lochkovian) trilobites and brachiopods from the west Balkhash Region,Kazakhstan and their significance for regional terrane dynamics

A moderately diverse Early Devonian (Lochkovian) trilobite and brachiopod association has been recovered from the lower part of the volcano-sedimentary Shakshagaily Formation, exposed on the western side of Lake Balkhash in central Kazakhstan. Its discovery demonstrates the presence of Lower Devonian marine deposits in the region. The trilobite assemblage includes representatives of six genera: the dalmanitid Kasachstania alperovichi nov. sp. is the dominant taxon, with other components being Ananaspis?, Leonaspis?, Maurotarion, Trimerus (Edgillia), and Warburgella. Associated brachiopods include species of Glossoleptaena, Leptaena, Protolepstostrophia, Pseudostrophochonetes, and Resserella. Whilst a significant proportion of these taxa show distinct links with the contemporaneous trilobite and brachiopod faunas of the north Balkhash Region, the occurrence of Trimerus (Edgillia) aff. kinglakensis Gill, 1949 suggests a possible link with the Lochkovian trilobite fauna of the Australasian sector of Gondwana. The west Balkhash Region preserves an extensive record of late Silurian to Early Devonian island arc volcanism, slope-rise sedimentation and olistostrome formation, which has invariably been ignored in models favouring early amalgamation of the Kazakhstanian terranes into a single continent by the end of the Ordovician.     

Late Miocene brackish Loxoconchidae (Crustacea, Ostracoda) from Italy

The Late Miocene Italian brackish Loxoconchidae are herein discussed and illustrated. Three genera and two subgenera have been recognized in the brackish Italian basins: Loxoconcha, Loxocorniculina, Loxoconchissa (Loxoconchissa) and Loxoconchissa (Loxocaspia). Taking into account the diagnostic characters of several Loxoconchidae genera, in this paper Loxocorniculina is raised at a generic rank, Loxocaspia is confirmed as a subgenus within genus Loxoconchissa and several new species are established: Loxoconchissa (Loxoconchissa) kinoi nov. sp., Loxoconchissa (Loxocaspia) cosentinoi nov. sp., Loxoconchissa (Loxocaspia) nuda nov. sp., Loxoconchissa (Loxocaspia) punctata nov. sp., Loxoconchissa (Loxocaspia) reticulata nov. sp., Loxoconchissa (Loxocaspia) tuberosa nov. sp. and Loxoconchissa (Loxocaspia) velonae nov. sp. Loxocorniculina is a typical Paratethyan genus which widespread into the Palaeo-Mediterranean during the late Messinian Lago-Mare event. Loxoconchissa was known to be widespread only in the Paratethyan realm and in this paper it is signalled for the first time in the Late Tortonian-early Messinian of Italy. The palaeobiogeography of these genera is discussed and the observed continuous distribution of Loxocorniculina against the disjunct distribution of Loxoconchissa leads to suggest that this latter genus underwent a passive dispersal via aquatic birds.     

The evolution of peafowl and other taxa with ocelli (eyespots): a phylogenomic approach

The most striking feature of peafowl (Pavo) is the males'' elaborate train, which exhibits ocelli (ornamental eyespots) that are under sexual selection. Two additional genera within the Phasianidae (Polyplectron and Argusianus) exhibit ocelli, but the appearance and location of these ornamental eyespots exhibit substantial variation among these genera, raising the question of whether ocelli are homologous. Within Polyplectron, ocelli are ancestral, suggesting ocelli may have evolved even earlier, prior to the divergence among genera. However, it remains unclear whether Pavo, Polyplectron and Argusianus form a monophyletic clade in which ocelli evolved once. We estimated the phylogeny of the ocellated species using sequences from 1966 ultraconserved elements (UCEs) and three mitochondrial regions. The three ocellated genera did form a strongly supported clade, but each ocellated genus was sister to at least one genus without ocelli. Indeed, Polyplectron and Galloperdix, a genus not previously suggested to be related to any ocellated taxon, were sister genera. The close relationship between taxa with and without ocelli suggests multiple gains or losses. Independent gains, possibly reflecting a pre-existing bias for eye-like structures among females and/or the existence of a simple mutational pathway for the origin of ocelli, appears to be the most likely explanation.     

Generic Delimitation and Phylogeny of the Subtribe Centaureinae (Asteraceae): A Combined Nuclear and Chloroplast DNA Analysis

Taxonomic complexity has hindered the partitioning of the artificial genus Centaurea, even though it has long been recognized as a polyphyletic assemblage. On the basis of morphology, pollen type, karyology and DNA sequence analysis, previous workers have defined five informal groups in the genus (Acrocentron,Centaureasensu stricto , Cyanus, Jacea and Psephellus). However, the precise delimitation of these groups and their relationships remain largely unknown. Moreover, although some informal groups have been established among the rest of the subtribe (Amberboa, Carthamus and Stemmacantha), many genera cannot be classified in any group. Newer molecular approaches are essential for resolving these problems. Sequences of the internal transcribed spacers (ITS) of nuclear ribosomal DNA and the chloroplast gene mat K were analysed for a comprehensive sample of the whole subtribe, with the aim of clarifying the delimitation and the phylogeny of the groups of the Centaureinae. Results largely confirm the suggested informal entities as natural groups, with some interesting changes of placement of some genera, especially in the Acrocentron and the Stemmacantha groups. Our results confirm that the sections of Centaurea with Dealbata pollen type should be classified as a different genus, Psephellus. In addition to morphology and suggested pollen type evolution, the ITS and mat K phylogenies are also supported by karyological evidence. Our results confirm that the natural delimitation of Centaurea that minimizes nomenclatural changes is possible only if a new type of the genus is designated.     

An upper Kungurian/lower Guadalupian (Permian) brachiopod fauna from the South Qiangtang Block in Tibet and its palaeobiogeographical implications

A brachiopod fauna including 15 species belonging to 14 genera is described from a thin carbonate succession of the Lugu Formation at the Anmu section in the northern part of the South Qiangtang Block, which is about 15 km south to the Longmu Co-Shuanghu Suture. The brachiopod fauna is late Kungurian or early Guadalupian in age in terms of the presence of the brachiopod species Vediproductus punctatiformis, “Cryptospirifer” omeishanensis, and Paraplicatifera regularis. This is also generally consistent with the age indicated by the fusulines (e.g., Cancellina, Chusenella, Monodiexodina, Nankinella, Neofusulinella, Pseudofusulina, and Sphaerulina) from this formation at the nearby Mari and Duoma A (DMA) sections. Palaeobiogeographically, the brachiopod fauna exhibits a typical Cathaysian affinity and all the species are reported commonly from the equivalents in South China and Cimmerian blocks, which strongly suggest that the South Qiangtang Block had drifted to a position in the warm-water or temperate regime close to South China.     

An Illustrated Key to the Cyst-Forming Genera and Species of Heteroderidae in the Western Hemisphere with Species Morphometrics and Distribution

Diagnoses of the cyst-forming genera of Heteroderidae (viz., Heterodera, Sarisodera, Globodera, Punctodera, Cactodera, and Dolichodera) and distribution and morphometrics of the 34 known cyst species in the Western Hemisphere are presented along with an illustrated key for the identification of these genera and species. The key is based mainly on cysts and larvae, and important morphological and diagnostic features are extensively shown by LM and SEM illustrations. The genus Bidera is placed as a new synonym under the genus Heterodera.     

Reappraisal of some Upper Devonian (Famennian) spiriferide brachiopods from the Band-e Bayan Domain (Afghanistan)

The upper and uppermost Famennian succession (Upper Devonian) of the Band-e Bayan Domain (also known as the Axial Zone), a Cimmerian terrane of western Afghanistan (northern margin of Gondwana), yielded diverse brachiopod faunas that are dominated by the spiriferides. Among the latter, six species belonging to four genera, previously erected by D. Brice in the seventies and also known from Iran, are reappraised on the basis of their type material and re-illustrated. The genera Enchondrospirifer and Eobrachythyris are transferred to the subfamilies Cyrtospiriferinae (Cyrtospiriferoidea) and Prospirinae (Spiriferoidea), respectively, whereas the ornament and micro-ornament of both Afghan species of Dichospirifer are documented. The genus Ghorispirifer nov. gen. (Cyrtiopsinae) is erected with Cyrtiopsis graciosa chakhaensis Brice as type species, and includes a second species, namely Cyrtiopsis lapparenti Brice. The new genus is characterized notably by the strong development of ventral apical callosities. Upper Devonian (Frasnian?) brachiopods from the Band-e Bayan Domain described by Maillieux in the first half of the 20th century are revised and photographically illustrated for the first time. The brachiopod generic diversity recognized in Afghanistan (Band-e Bayan Domain, Central Mountains) prior to the Hangenberg Crisis is very high in some sections of the Band-e Bayan Domain (Rhuk pass section, and to a lesser extent at Robat-e-Pai), as also observed in contemporaneous successions of South China and contrary to what is reported in Western Europe (Franco-Belgian Basin for instance).     

The Historical Speciation of Mauremys Sensu Lato: Ancestral Area Reconstruction and Interspecific Gene Flow Level Assessment Provide New Insights

Mauremys sensu lato was divided into Mauremys, Chinemys, Ocadia, and Annamemys based on earlier research on morphology. Phylogenetic research on this group has been controversial because of disagreements regarding taxonomy, and the historical speciation is still poorly understood. In this study, 32 individuals of eight species that are widely distributed in Eurasia were collected. The complete mitochondrial (mt) sequences of 14 individuals of eight species were sequenced. Phylogenetic relationships, interspecific divergence times, and ancestral area reconstructions were explored using mt genome data (10,854 bp). Subsequent interspecific gene flow level assessment was performed using five unlinked polymorphic microsatellite loci. The Bayesian and maximum likelihood analyses revealed a paraphyletic relationship among four old genera (Mauremys, Annamemys, Chinemys, and Ocadia) and suggested the four old genera should be merged into the genus (Mauremys). Ancestral area reconstruction and divergence time estimation suggested Southeast Asia may be the area of origin for the common ancestral species of this genus and genetic drift may have played a decisive role in species divergence due to the isolated event of a glacial age. However, M. japonica may have been speciated due to the creation of the island of Japan. The detection of extensive gene flow suggested no vicariance occurred between Asia and Southeast Asia. Inconsistent results between gene flow assessment and phylogenetic analysis revealed the hybrid origin of M. mutica (Southeast Asian). Here ancestral area reconstruction and interspecific gene flow level assessment were first used to explore species origins and evolution of Mauremys sensu lato, which provided new insights on this genus.     

Taxonomic study of the tetrahedral, pentagonal and hexagonal spongy spumellarian Radiolaria from the middle Carnian (Late Triassic) of the Köseyahya nappe (Elbistan, SE Turkey) and other Triassic localities

This article is a taxonomic study of all spongy radiolarian taxa with five to six coplanar and four tetrahedrally disposed spines or spongy arms occurring in the middle Carnian from the Köseyahya section, near the town of Elbistan, SE Turkey. This fauna is characteristic of the Tetraporobrachia haeckeli radiolarian Zone, and comes from an 8 m thick succession of clayey–cherty limestones occurring at the lower part of the section. In addition, a few species from the Middle and Upper Triassic from other areas have been also included in this study to improve some generic diagnoses and to better understand the diversity and evolutionary trends of some genera, subfamilies and families. The taxonomy at the generic and suprageneric levels is based primarily on the types of microsphere. This new approach allowed new taxonomic arrangements of genera and suprageneric units, and suggested new and unexpected phylogenetic relationships among these radiolarians and between them and younger radiolarians. The authors discuss and describe 42 species, of which 36 are new, and 12 genera of which three are new (Charlottalum, Pentaspongodisculus, and Trimiducaella). The genera Pseudohagiastrum Pessagno, Natraglia Pessagno, Cantalum Pessagno and others are reinterpreted. All the genera studied, except Charlottalum, are assigned to three subfamilies, of which two (Pseudohagiastrinae and Trimiducinae) are new, and to two families (Angulobracchiidae and Relindellidae). The genus Charlottalum is described to replace the genus Cantalum, which has been erroneously used until present for Late Triassic pantanelliids with four tetrahedrally disposed three-bladed spines.     

Phylogeny of Sphingomonas species that degrade pentachlorophenol

Four pentachlorophenol (PCP)-degrading bacteria isolated from geographically diverse areas have been examined in detail as regards their physiology and phylogeny. According to traditional biochemical methods, these strains had been classified as members of the genera Arthrobacter, Flavobacterium, Pseudomonas, and Sphingomonas. The PCP degradation pathway has been studied extensively in Sphingomonas (Flavobacterium) sp strain ATCC 39723 and the first three degradation steps catalyzed by a PCP-4-monooxygenase (PcpB) and a reductive dehalogenase (PcpC) that functions twice are well established. A fourth step appears to involve ring-fission of the aromatic nucleus (PcpA). Molecular analyses revealed that the PCP degradation pathway in these four strains was rather conserved, leading to a phylogenetic analysis using 16S rDNA. The results revealed a much closer phylogenetic relationship between these organisms than traditional classification indicated, placing them into the more recently established genus Sphingomonas where they may even represent a single species. With 16S rDNA analysis, many bacterial isolates involved in degradation of xenobiotic compounds that were previously classified into diverse genera have been reclassified into the genus Sphingomonas.

Systematics and evolution of the genus Torrubiella (Hypocreales, Ascomycota)

Torrubiella is a genus of arthropod-pathogenic fungi that primarily attacks spiders and scale insects. Based on the morphology of the perithecia, asci, and ascospores, it is classified in Clavicipitaceae s. lat. (Hypocreales), and is considered a close relative of Cordyceps s. 1., which was recently reclassified into three families (Clavicipitaceae s. str., Cordycipitaceae, Ophiocordycipitaceae) and four genera (Cordyceps s. str, Elaphocordyceps, Metacordyceps, and Ophiocordyceps). Torrubiella is distinguished morphologically from Cordyceps s. lat. mainly by the production of superficial perithecia and the absence of a well-developed stipitate stroma. To test and refine evolutionary hypotheses regarding the placement of Torrubiella and its relationship to Cordyceps s. lat., a multi-gene phylogeny was constructed by conducting ML and Bayesian analyses. The monophyly of Torrubiella was rejected by these analyses with species of the genus present in Clavicipitaceae, Cordycipitaceae, and Ophiocordycipitaceae, and often intermixed among species of Cordyceps s. lat. The morphological characters traditionally used to define the genus are, therefore, not phylogenetically informative, with the stipitate stromata being gained and/or lost several times among clavicipitaceous fungi. Two new genera (Conoideocrella, Orbiocrella) are proposed to accommodate two separate lineages of torrubielloid fungi in the Clavicipitaceae s. str. In addition, one species is reclassified in Cordyceps s. str. and three are reclassified in Ophiocordyceps. The phylogenetic importance of anamorphic genera, host affiliation, and stipitate stromata is discussed.
