Multiple genes phylogeny and morphological characters reveal <Emphasis Type="Italic">Dextrinoporus aquaticus</Emphasis> gen. et sp. nov. (Polyporales,Basidiomycota) from southern China

Dextrinoporus aquaticus gen. et sp. nov. is proposed based on ITS, nLSU, RPB2, and mtSSU genes molecular phylogeny and morphological characteristics from southwestern China. The new species is characterized by an annual, pileate basidiocarp with a poroid hymenophore, a monomitic hyphal system, thick-walled generative hyphae with dextrinoid and cyanophilous reactions, presence of dendrohyphidia and ellipsoid, thin-walled, and acyanophilous basidiospores. Phylogenetic analyses based on four gene sequences indicate that D. aquaticus belongs to Polyporaceae in which it has an isolated position, and the new taxon is related to the clade of Lopharia cinerascens and Dentocorticium sulphurellum.     

Revision of the taxonomic status of the genus <Emphasis Type="Italic">Gloeoporus</Emphasis> (Polyporales,Basidiomycota) reveals two new species

Gloeoporus Mont. is characterized by an easily separated gelatinous hymenophore and a continuous hymenium over the pore mouth. Recent molecular taxonomic and phylogenetic research showed that morphological grouping of Gloeoporus is polyphyletic. The lack of comprehensive phylogenetic studies of Gloeoporus exacerbates confusion in determining the taxonomic position of the genus. To delimit the genus Gloeoporus, we performed multi-locus phylogenetic analysis using the internal transcribed spacer (ITS) region, the nuclear large subunit ribosomal DNA (LSU), and the second-largest subunit of RNA polymerase II (rpb2). The phylogenetic analyses revealed that current delimitation of Gloeoporus is not monophyletic. Gloeoporus s.s. includes mostly clamped species lacking cystidia. Some species of Gloeoporus featuring simple septa and cystidia are proposed to be renamed to Meruliopsis. Two new species of Gloeoporus were also observed and they are named Gloeoporus africanus and Gloeoporus orientalis.     

<Emphasis Type="Italic">Leifiporia rhizomorpha</Emphasis> gen. et sp. nov. and <Emphasis Type="Italic">L. eucalypti</Emphasis> comb. nov. in Polyporaceae (Basidiomycota)

A new poroid wood-inhabiting fungal genus, Leifiporia, is proposed, based on morphological and molecular evidence, which is typified by L. rhizomorpha sp. nov. The genus is characterized by an annual growth habit, resupinate basidiocarps with white to cream pore surface, a dimitic hyphal system with generative hyphae bearing clamp connections and branching mostly at right angles, skeletal hyphae present in the subiculum only and distinctly thinner than generative hyphae, IKI–, CB–, and ellipsoid, hyaline, thin-walled, smooth, IKI–, CB– basidiospores. Sequences of ITS and LSU nrRNA gene regions of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony and Bayesian inference methods. The phylogenetic analysis based on molecular data of ITS + nLSU sequences showed that Leifiporia belonged to the core polyporoid clade and was closely related to Diplomitoporus overholtsii and Lopharia cinerascens, and then grouped with Pycnoporus and Trametes. Further investigation was obtained for more representative taxa in the Polyporaceae based on nLSU sequences, in which the results demonstrated that the genus Leifiporia formed a monophyletic lineage with a strong support (100 % BS, 100 % BP, 1.00 BPP). Both morphological and molecular evidence confirmed the placement of the new genus in the core polyporoid clade. In addition, a new combination, Leifiporia eucalypti, is proposed based on examination of its type material and phylogeny.     

<Emphasis Type="Italic">Ceriporiopsis kunmingensis</Emphasis> sp. nov. (Polyporales,Basidiomycota) evidenced by morphological characters and phylogenetic analysis

A new poroid wood-inhabiting fungal species, Ceriporiopsis kunmingensis sp. nov., is proposed based on morphological and molecular characters. The species is characterized by resupinate basidiocarps with pale cinnamon-buff to ochreous color when dry; generative hyphae unbranched and subparallel along the tubes; presence of hyphal ends; allantoid basidiospores, 4.5–5 × 1.5–2 μm. The internal transcribed spacer (ITS) and large subunit (LSU) regions of nuclear ribosomal RNA gene sequences of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony, and Bayesian inference methods. The phylogenetic analysis based on molecular data of ITS?+?nLSU sequences showed that C. kunmingensis belonged to the phlebioid clade, formed a monophyletic lineage with a strong support (100% BS, 100% BP, 1.00 BPP), and was closely related to Phlebia aurea, and then grouped with P. livida and P. subserialis. Both morphological and molecular characters confirmed the placement of the new species in Ceriporiopsis.     

Myrothecium-like (Ascomycota,Hypocreales) species from tropical areas: <Emphasis Type="Italic">Digitiseta</Emphasis> gen. nov. and additions to <Emphasis Type="Italic">Inaequalispora</Emphasis> and <Emphasis Type="Italic">Parvothecium</Emphasis>

Inaequalispora and Parvothecium are two myrothecium-like, closely related genera of Hypocreales. They are also morphologically similar, sharing sporodochial conidiomata, penicillate conidiophores, fusiform to ellipsoidal conidia accumulating in a green slimy drop, and hypha-like setoid extensions emerging through the conidial mass. During a revision of myrothecium-like isolates originating from rainforest areas of South America (Ecuador, Brazil) and Southeast Asia (Singapore), multilocus phylogenetic inferences (based on DNA sequence data of ITS, partial nuc 28S, and partial tef1a, rpb2 and tub2) and morphological studies concordantly revealed the occurrence of two undescribed species of Inaequalispora (I. longiseta sp. nov. and I. cylindrospora sp. nov.) and one undescribed species of Parvothecium (P. amazonensesp. nov.). Myrothecium setiramosum, M. dimorphum, and two undescribed taxa form the base of a new lineage, sister to the current Parvothecium lineage. This lineage is recognized as Digitiseta gen. nov., typified by D. setiramosa comb. nov. Digitiseta dimorpha comb. nov. is also proposed, and the new species D. parvodigitata sp. nov. and D. multidigitata sp. nov. are described.     

Molecular taxonomy and morphological characterization reveal new species and new host records of <Emphasis Type="Italic">Torula</Emphasis> species (Torulaceae,Pleosporales)

Four new species and two new host records of Torula (Torulaceae, Pleosporales) are described and illustrated from herbaceous litter collected in Italy and Thailand. The new species possess colony, conidiophore and conidial characteristics that fit within the generic concept of Torula. Detailed morphological observations clearly demarcate four of these from extant species and are hence described as new (Torula chiangmaiensis sp. nov., Torula pluriseptata sp. nov., Torula chromolaenae sp. nov., Torula mackenziei sp. nov.). Details of asexual morphs are described, and justifications for establishing these new species are provided. The nuclear are sequenced ribosomal RNA genes as well as protein coding genes to infer phylogenetic relationships and discuss phylogenetic affinities with morphologically similar species. Our morphological distinction is further supported by phylogenetic discrimination. In particular, phylogenies depict a close relationship of Torula chiangmaiensis and T. pluriseptata to T. hollandica, while T. chromolaenae and T. mackenziei constitute an independent phylogenetic lineage basal to T. herbarum and T. ficus. Torula ficus and T. masonii are also described and their phylogeny investigated as new host records from Bidens pilosa and Iris germanica, respectively.     

<Emphasis Type="Italic">Halymenia johorensis</Emphasis> sp. nov. (Halymeniaceae,Rhodophyta), a new foliose red algal species from Malaysia

A new Halymenia species, Halymenia johorensis sp. nov., from southern Peninsular Malaysia is proposed based on plastid-encoded large subunit of ribulose-1,5-bisphosphate carboxylase/oxygenase (rbcL) gene analyses and detailed morphological observations. The new species is characterized by having (1) elliptical, oblong, or irregularly shaped blades, incised with some perforations, arising from a narrow-cuneate stipe attached to a discoid holdfast; (2) blades with a cartilaginous and gelatinous texture, a smooth to rugose surface, and irregularly dentate and cleft margins; and (3) isodiametric outer cortical cells and rounded to stellate inner cortical cells. RbcL sequence analyses have shown H. johorensis to be genetically distinct from other Halymenia species. Although H. johorensis is sister to Halymenia plana, these two species can be distinguished both molecularly and morphologically. Further studies are necessary to investigate the phylogenetic relationships and species diversity in this genus.     

<Emphasis Type="Italic">Purpureocorticium microsporum</Emphasis> (Basidiomycota) gen. et sp. nov. from East Asia

A corticioid fungal species found in mountainous Taiwan, and Yunnan Province of China, is described as a new genus and new species: Purpureocorticium microsporum (Agaricomycetes, Basidiomycota). Morphological study and phylogenetic analyses based on sequence data respectively derived from the large subunit nuclear ribosomal RNA gene (LSU nrDNA) alone and the combined dataset of LSU nrDNA and translation elongation factor 1-α gene (tef1-α) indicated that Purpureocorticium does not belong to any clade of the Agaricomycetes. Purpureocorticium and P. microsporum are characterized by having a resupinate basidiocarp with smooth hymenial surface which turns purple in KOH, and becomes purplish after storage, microscopically having compact texture of subiculum, nodose-septate thin-walled generative hyphae, absence of cystidia, basidia subclavate with a median constriction, or utriform, bearing ovate-ellipsoid small-sized basidiospores, which are smooth and thin-walled, inamyloid, and nondextrinoid. The new combination Rhizochaete rubescens is proposed, based on morphological and phylogenetic evidences.     

Three new species and one new combination of <Emphasis Type="Italic">Gypsoplaca</Emphasis> (lichenized Ascomycota) from the Hengduan Mountains in China

Three new species are described as follows: Gypsoplaca alpina H. X. Shi and Li S. Wang, G. bullata H. X. Shi and Li S. Wang, and G. rosulata H. X. Shi, Li S. Wang, and Timdal sp. nov. Gypsoplaca alpina is characterized by a small thallus, upper cortex with very thick gelatinized layer, ascocarp warty with a cerebriform ridging, and by growing on soil in alpine meadows. Gypsoplaca bullata characterized by having bullate ascocarp, uneven to bullate thallus. Gypsoplaca rosulata is characterized by rosulate thallus and 4–6-spored asci. The new combination Gypsoplaca blastidiata (Zhurb) H. X. Shi and Li S. Wang comb. & stat. nov. is proposed. A phylogenetic tree is established, based on combined sequences of ITS and nrLSU, and all species formed monophyletic clades. Two main chemical compounds, brialmontin and sesterterpenes, are reported for the first time from Gypsoplaca by analysis of NMR and MS data. Triterpenoids are absent in Chinese Gypsoplaca specimens.     

A new species of the pufferfish <Emphasis Type="Italic">Eotetraodon</Emphasis> (Tetraodontiformes,Tetraodontidae) from the Eocene of the Northern Caucasus

The Eocene pufferfish genus Eotetraodon (Tetraodontidae) has previously been known only on the basis of E. pygmaeus (Zigno, 1887) from the lowermost Middle Eocene of Monte Bolca, Italy. To Eotetraodon we now add E. gornylutshensis sp. nov. from the uppermost Middle Eocene of the Kuma Horizon of the northern Caucasus (Gorny Luch locality). E. gornylutshensis sp. nov. differs from E. pygmaeus by having much longer ribs and one less vertebra in the caudal peduncle.     

<Emphasis Type="Italic">Dagysina</Emphasis>—A new nodosariid genus (foraminifera) from the Upper Triassic of Kotel’ny Island,New Siberian Islands

A new nodosariid genus Dagysina gen. nov. with the type species Dagysina novosibirica sp. nov. is described from the Norian deposits of Kotel’ny Island, New Siberian Islands. A close phylogenetic relationship between Dagysina and the Early Liassic Frondiculinita is revealed based on morphological resemblance and an identical geographic range.     

<Emphasis Type="Italic">Calcarisporium xylariicola</Emphasis> sp. nov. and introduction of <Emphasis Type="Italic">Calcarisporiaceae</Emphasis> fam. nov. in Hypocreales

During a survey of fungicolous fungi, a novel taxon from the surface of stroma of an unidentified Xylaria species was collected. Phylogenetic analyses showed that this taxon clustered with Calcarisporium sp. and C. arbuscula isolates, but was resolved as a distinct species. A detailed morphological examination coupled with phylogenetic analysis indicated that the taxon represented a new species. Calcarisporium xylariicola sp. nov. is thus introduced. The new taxon is characterized by short conidiophores with swollen bases and less length/width ratio of conidia that distinguish it from other Calcarisporium species. Calcarisporium is presently placed in Hypocreales genera, incertae sedis genus. Species in the genus are largely fungicolous, or occasionally caulicolous or foliicolous, and have hyaline, erect, verticillate conidiophores and sympodial, polyblastic conidiation. A phylogenetic analysis of combined SSU, ITS, LSU, TEF and RPB2 sequence data from Calcarisporium species and other taxa in Hypocreales indicate that Calcarisporium is a distinct lineage from other families. Therefore, a new family, Calcarisporiaceae, in Hypocreales is introduced.     

Taxonomic revisions in the Microstromatales: two new yeast species,two new genera,and validation of <Emphasis Type="Italic">Jaminaea</Emphasis> and two <Emphasis Type="Italic">Sympodiomycopsis</Emphasis> species

Environmental sampling yielded two yeast species belonging to Microstromatales (Exobasidiomycetes, Ustilaginomycotina). The first species was collected from a leaf phylloplane infected by the rust fungus Coleosporium plumeriae, and represents a new species in the genus Jaminaea, for which the name Jaminaea rosea sp. nov. is proposed. The second species was isolated from air on 50% glucose media and is most similar to Microstroma phylloplanum. However, our phylogenetic analyses reveal that species currently placed in Microstroma are not monophyletic, and M. phylloplanum, M. juglandis and M. albiziae are not related to the type species of this genus, M. album. Thus, Pseudomicrostroma gen. nov. is proposed to accommodate the following species: P. glucosiphilum sp. nov., P. phylloplanum comb. nov. and P. juglandis comb. nov. We also propose Parajaminaea gen. nov. to accommodate P. albizii comb. nov. and P. phylloscopi sp. nov. based on phylogenetic analyses that show these are not congeneric with Jaminaea or Microstroma. In addition, we validate the genus Jaminaea, its respective species and two species of Sympodiomycopsis and provide a new combination, Microstroma bacarum comb. nov., for the anamorphic yeast Rhodotorula bacarum. Our results illustrate non-monophyly of Quambalariaceae and Microstromataceae as currently circumscribed. Taxonomy of Microstroma and the Microstromataceae is reviewed and discussed. Finally, analyses of all available small subunit rDNA sequences for Jaminaea species show that J. angkorensis is the only known species that possess a group I intron in this locus, once considered a potential feature indicating the basal placement of this genus in Microstromatales.     

<Emphasis Type="Italic">Orientosirenites</Emphasis>, a New Ammonoid Genus (Sirenitidae; Ammonoidea) from the Upper Carnian of the Boreal Realm

The ammonoid family Sirenitidae from the Upper Carnian yakutensis Zone of northern Middle Siberia and Northeastern Asia is revised. A new genus Orientosirenites gen. nov. with the type species O. bytschkovi sp. nov. is established based on the study of the main morphological characters of the shell. The new genus and the species O. bytschkovi are described and the species O. yakutensis (Kiparisova) is redescribed. The new data allow the taxonomic composition and the distribution of the Carnian ammonoids of the Boreal Realm to be updated.     

A new species of the conodont genus <Emphasis Type="Italic">Polygnathus</Emphasis> from the Tournaisian of the northern Urals,Chernyshev Ridge and Pai-Khoi

A new conodont species, Polygnathus postvogesi sp. nov., from the Tournaisian deepwater deposits of the northern Urals, southeastern part of the Chernyshev Ridge, and central Pai-Khoi is described. The new species continue the phylogenetic lineage of the Late Devonian polygnathid P. marginvolutus Gedik, P. vogesi Ziegler.     

Phylogeny and morphology of the <Emphasis Type="Italic">Peziza ammophila</Emphasis> complex (Pezizales,Ascomycota), with description of two new species and a new form

This study was focused on species of Peziza belonging to the “P. ammophila” complex, using both morphological and molecular approaches. Molecular and morphological analyses showed that several taxa are hidden under the name “ammophila” and, as a consequence, two additional species and one form are established: P. hellenica sp. nov., P. oceanica sp. nov. and P. ammophila f. megaspora f. nov. On the basis of the data that we have, these taxa seem to be related to some geographical areas; P. ammophila appears to be prevalent in northern, central and southern Europe, its f. megaspora is distributed in France and in the Netherlands, P. hellenica comes from Greece and P. oceanica from New Zealand. A cryptic species, not yet circumscribed satisfactorily, is described as P. deceptiva ad int. Moreover, the problem concerning the identification of P. ammophila is raised, the species is epitypified with a sequenced collection from Sicily (Italy) and a key to the species of the complex is provided.     

Review of the genus <Emphasis Type="Italic">Banjos</Emphasis> (Perciformes: Banjosidae) with descriptions of two new species and a new subspecies

A taxonomic review of the genus Banjos (Perciformes: Banjosidae), previously restricted to a single species, Banjos banjos (Richardson 1846), recorded from the northwestern Pacific Ocean from the South China Sea north to Japan, as well as Lombok (Indonesia), New Caledonia and Australia, resulted in the recognition of three species, including B. banjos (northwestern Pacific Ocean, Indonesia and western Australia), Banjos aculeatus sp. nov. (eastern Australia) and Banjos peregrinus sp. nov. [northern Australia (Timor Sea)]. Records of B. banjos from New Caledonia probably also represent B. aculeatus, which is clearly distinct from other congeners in having a relatively long, strongly serrated spine at the posteroventral angle of the preopercle and an entirely dusky membrane on the spinous dorsal fin in juveniles < ca. 70 mm SL, in addition to slightly longer first and second dorsal-fin spines. Banjos peregrinus is characterized by a relatively greater head length, orbit diameter, postorbital length and pre-pelvic-fin length, as well as poorly developed serration of the exposed margin of the cleithrum. Within B. banjos, a population from the southeastern Indian Ocean, including Indonesia and western Australia, is regarded as a distinct subspecies (Banjos banjos brevispinis ssp. nov.), distinguishable from B. b. banjos from the northwestern Pacific Ocean by a relatively narrow least interorbital width, and shorter second and eighth dorsal-fin spines. Ontogenetic morphological changes within the genus and the status of the holotype of Anoplus banjos Richardson 1846 are discussed in detail.
