Strain variability of <Emphasis Type="Italic">Irpex Lacteus</Emphasis> basidiomycetes in the synthesis of specific milk-clotting proteinases

The ability to synthesize milk-clotting (rennet) proteinases was studied in eight strains of Irpex Lacteus basidiomycetes. It was found that the studied I. lacteus strains are characterized by different enzyme activities in their culture liquid. For I. lacteus strains 2425, 2426, and 2427, the maximum milk-clotting activity was detected during the exponential growth phase on the 15th day of cultivation on glucose–peptone medium. These I. lacteus strains are the most prospective milk-clotting enzyme producers for further research and practical application. I. lacteus strains 2421, 2422, 2423, 2424, and 2428 showed lower values of the enzyme activity and require additional research to determine the optimal culture conditions.     

Morphology and molecules reveal the alien <Emphasis Type="Italic">Posthodiplostomum centrarchi</Emphasis> Hoffman, 1958 as the third species of <Emphasis Type="Italic">Posthodiplostomum</Emphasis> Dubois, 1936 (Digenea: Diplostomidae) in Europe

Metacercariae of two species of Posthodiplostomum Dubois, 1936 (Digenea: Diplostomidae) were subjected to morphological and molecular studies: P. brevicaudatum (von Nordmann, 1832) from Gasterosteus aculeatus (L.) (Gasterosteiformes: Gasterosteidae), Bulgaria (morphology, cox1 and ITS1-5.8S-ITS2) and Perca fluviatilis L. (Perciformes: Percidae), Czech Republic (morphology, cox1, ITS1-5.8S-ITS2 and 28S); and P. centrarchi Hoffman, 1958 from Lepomis gibbosus (L.) (Perciformes: Centrarchidae), Bulgaria (morphology, cox1 and ITS1-5.8S-ITS2) and Slovakia (cox1 and ITS1-5.8S-ITS2). In addition, cercariae of P. cuticola (von Nordmann, 1832) from Planorbis planorbis (L.) (Mollusca: Planorbidae), Lithuania (morphology and cox1) and metacercariae of Ornithodiplostomum scardinii (Schulman in Dubinin, 1952) from Scardinius erythrophthalmus (L.) (Cypriniformes: Cyprinidae), Czech Republic, were examined (morphology, cox1, ITS1-5.8S-ITS2 and 28S). These represent the first molecular data for species of Posthodiplostomum and Ornithodiplostomum Dubois, 1936 from the Palaearctic. Phylogenetic analyses based on cox1 and ITS1-5.8S-ITS2, using O. scardinii as the outgroup and including the three newly-sequenced Posthodiplostomum spp. from Europe and eight published unidentified (presumably species-level) lineages of Posthodiplostomum from Canada confirmed the distinct status of the three European species (contrary to the generally accepted opinion that only P. brevicaudatum and P. cuticola occur in the Palaearctic). The subspecies Posthodiplostomum minimum centrarchi Hoffmann, 1958, originally described from North America, is elevated to the species level as Posthodiplostomum centrarchi Hoffman, 1958. The undescribed “Posthodiplostomum sp. 3” of Locke et al. (2010) from centrarchid fishes in Canada has identical sequences with the European isolates of P. centrarchi and is recognised as belonging to the same species. The latter parasite, occurring in the alien pumpkinseed sunfish Lepomis gibbosus in Europe, is also supposed to be alien for this continent. It is speculated that it colonised Europe long ago and is currently widespread (recorded in Bulgaria, Slovakia and Spain); based on the cox1 sequence of an adult digenean isolate from the Ebro Delta, Spain, only the grey heron (Ardea cinerea L.) (Ciconiiformes: Ardeidae) is known to be its definitive host in Europe.     

Polyphasic characterisation of three novel species of <Emphasis Type="Italic">Paraboeremia</Emphasis>

Paraboeremia was recently introduced for a distinct lineage in the family Didymellaceae. Currently, three species are included, i.e. P. adianticola, P. putaminum and P. selaginellae, all of which are plant pathogens. Paraboeremia is morphologically similar to Phoma but phylogenetically distinct. In this paper, three new species, i.e. Paraboeremia camelliae isolated from Camellia sp., P. litseae from Litsea sp., and P. oligotrophica from cave limestone, are described, illustrated and compared with closely related taxa. Phylogenetic analysis based on the multi-locus sequences of the internal transcribed spacer regions 1 and 2 and 5.8S nuclear ribosomal RNA gene (ITS), partial large subunit 28S nrDNA region (LSU), partial β-tubulin (TUB2) gene and RNA polymerase II (RPB2) gene regions confirmed the distinction of these species in Paraboeremia. These three new species were discovered from habitats and hosts that are previously unknown from this genus.     

Morphological and molecular taxonomy of novel species <Emphasis Type="Italic">Pleurotheciaceae</Emphasis> from freshwater habitats in Yunnan,China

The diversity of lignicolous freshwater fungi of the Greater Mekong Subregion are currently being studied. In this paper, 18 fresh collections of Pleurotheciaceae from submerged wood in freshwater are characterized based on morphological characters and analyses of ITS, LSU, SSU and RPB2 sequence data. Six new species of Pleurotheciella (P. aquatica, P. fusiformis, P. guttulata, P. lunata, P. saprophytica, P. submersa), one new Phaeoisaria species (Ph. aquatica) and one new Pleurothecium species (Pl. aquaticum) are introduced based on their distinct morphology and evidence from molecular phylogeny. Pleurotheciella uniseptata, Phaeoisaria clematidis and Pleurothecium pulneyense are also redescribed and phylogenetic relationships assessed herein, these species are the first records for China.     

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.     

Two new species of <Emphasis Type="Italic">Pseudopyricularia</Emphasis> from Iran

Two new species, Pseudopyricularia hyrcaniana and P. iraniana, are described, illustrated, and discussed in this paper. Phylogenetic analyses of the large subunit of the ribosomal RNA gene cluster and their internal transcribed spacer regions, and protein encoding gene introns and exons, including the largest subunit of the RNA polymerase II and calmodulin, confirmed their placement in Pseudopyricularia. Pseudopyricularia hyrcaniana was isolated as a pathogen from leaves of Cyperus alternifolius, while P. iraniana was from Juncus sp. Conidia of P. hyrcaniana are obclavate and 1-septate; those of P. iraniana are fusiform or cylindrical and 2-septate. Analyses of multigene sequences confirm the distinction between P. hyrcaniana and P. iraniana, and reveal their relationship with their allies in Pyriculariaceae.     

Revision of the shield-bug genera <Emphasis Type="Italic">Holcostethus</Emphasis> Fieber and <Emphasis Type="Italic">Peribalus</Emphasis> Mulsant et Rey (Heteroptera,Pentatomidae) of the Palaearctic Region

A complex of the heteropteran genera centering around Peribalus Mulsant et Rey and Holcostethus Fieber is considered. The genus Dryadocoris Kirkaldy reveals no relationship with the above genera and is believed to represent a separate clade of the family Pentatomidae. The genera Peribalus and Holcostethus are revised. The former includes three subgenera: Peribalus s. str. with two species, Asioperibalus subgen. n. (type species Cimex inclusus Dohrn) with six species, and Tianocoris subgen. n. (type species Holcostethus manifestus Kiritshenko) with two species. Holcostethus embraces two subgenera: Holcostethus s. str. and the monotypic Enigmocoris subgen. n. (type species H. fissiceps Horváth). Two new species are described: Peribalus tianshanicus sp. n. from the Tien Shan Mts. and P. przewalskii sp. n. from the northern part of China (Huan He River). P. capitatus Jakovlev and P. vernalis (Wolff) are downgraded to subspecies of P. strictus (F.). P. ovatus Jakovlev is synonymized with P. inclusus (Dohrn). Two new monotypic genera related to the revised complex of genera are established, Paraholcostethus gen. n. (type species Peribalus breviceps Horváth) and Himalayastethus gen. n. (type species H. pilosus sp. n. from Kashmir). A key to, and morphometric characters for all the taxa considered are provided. The key characters, including both male and female genitalia, are illustrated, and distributional maps are given.     

Revision of <Emphasis Type="Italic">Protohydnum</Emphasis> (Auriculariales,Basidiomycota)

Three species currently addressed to Protohydnum (Auriculariales) are studied with morphological and DNA methods. The genus Protohydnum is retained for the type species only, P. cartilagineum, recently re-collected in Brazil. The European species, P. piceicola, is not congeneric with P. cartilagineum and, therefore, placed in its own genus, Hyalodon, gen. nov. Another Hyalodon species, H. antui, is described from East Asia. The third member of Protohydnum sensu lato, P. sclerodontium from South-East Asia, is transferred to Elmerina.     

Local Knowledge on the Uses,Habitat, and Change in Abundance of Multipurpose <Emphasis Type="Italic">Mimusops</Emphasis> Species in Benin

Multipurpose NTFP species typically experience higher harvest demand because of their multiple uses, which, when combined with unsustainable land use practices, may threaten population viability. We assessed local knowledge on the uses, habitat, and population status of Mimusops andongensis and Mimusops kummel, both multipurpose NTFP species in Benin, to promote their valorization and conservation and thus sustain local knowledge on their uses for domestication issues. One hundred households were randomly selected for structured interviews for M. andongensis and 500 for M. kummel. The relationship between age, sex, and ethnic groups and the species uses was assessed using comparison and correspondence analyses. Nearly all organs of the species were used. Both species were mainly exploited for medicinal purposes but also in construction and as firewood. We found similarities in some uses of the species organs, although the species occur in different ecological zones and are used by different ethnic groups. This result should be considered for the valorization of the species. Most informants reported that populations of M. andongensis were decreasing, although some felt that they were increasing, whereas less than one-third said that M. kummel was decreasing. There were strong relationships between gender, age, and ethnic affiliation of the users and the exploited organs of both species. Potential uses exist based on both the past and current uses of the species and in comparison to other countries where they are exploited. Local ethnoecological knowledge and practices will help to valorize and conserve the species. However, further research on the species’ seed germination and propagation ability are also necessary.     

The first record of <Emphasis Type="Italic">Pronotalia</Emphasis> Gradwell, 1957 (Hymenoptera,Eulophidae) Wasps from Georgia

Four species of Pronotalia Gradwell (Hymenoptera, Eulophidae: Tetrastichinae) are recorded from the Lagodekhi Reserve (Georgia). Formerly, only P. carlinarum (Szelényi et Erdös) was known from Transcaucasia (Armenia) (Kostjukov, 1978). Pronotalia fiorii (Domenichini), P. orobanchiae Graham, and P. trypetae Gradwell are recorded for Georgia and Transcaucasia for the first time. In addition to these species, only 4 species are known from Europe and Anatolia: P. erzurumica Doganlar, P. hungarica (Erdös), P. inflata Graham, and P. tortumensis Doganlar; thus, 50% of Pronotalia species from Europe and Anatolia occur in the Lagodekhi Reserve.     

Induction of Sexual Reproduction in Single A<Superscript>2</Superscript> Isolates of <Emphasis Type="Italic">Phytophthora</Emphasis> Species by <Emphasis Type="Italic">Trichoderma viride</Emphasis>

ABOUT half the species of Phytophthora, including many important plant pathogens such as P. palmivora, P. cinnamomi and P. infestans, are heterothallic. Consistent induction of sexual reproduction in agar cultures of heterothallic species requires the pairing of isolates of the two compatibility groups, A¹ and A² (refs. 1–3). Although sex organs are occasionally formed in cultures of single isolates, such isolates though intrinsically bisexual are normally self-sterile^2–3. In consequence it has been assumed that in nature the presence of both compatibility types is required for the formation of oospores.     

Uncovered Diversity of a Predominantly Andean Butterfly Clade in the Brazilian Atlantic Forest: a Revision of the Genus <Emphasis Type="Italic">Praepedaliodes</Emphasis> Forster (Lepidoptera: Nymphalidae,Satyrinae, Satyrini)

The genus Praepedaliodes Forster, 1964, the only representative of the mega-diverse mostly Andean Pedaliodes complex lineage in the Brazilian Atlantic Forest, is revised. Prior to this study, four species were known, P. phanias (Hewitson, 1862), P. granulata (Butler, 1868), P. amussis (Thieme, 1905) and P. exul (Thieme, 1905). Here, a further six are described, all from SE Brazil, expanding to 10 the number of species in this genus. Lectotypes are designated for P. phanias, P. granulata and P. amussis. The genus is most diverse in the Serra da Mantiqueira (São Paulo, Rio de Janeiro, Minas Gerais) and in the Serra Geral (Paraná, Santa Catarina) with seven species occurring in both ranges. Praepedaliodes phanias is the most widespread species and the only one found in the western part of the Atlantic Forest; only this species and P. duartei Dias, Dolibaina & Pyrcz n. sp. occurring to near sea level. Other species, P. zaccae Dolibaina, Dias & Pyrcz n. sp., P. francinii Freitas & Pyrcz n. sp., P. sequeirae Pyrcz, Dias & Dolbaina n. sp., P. landryi Pyrcz & Freitas n. sp. and P. pawlaki Pyrcz & Boyer n. sp. are strictly montane and the highest species richness is reached at 1400–1800 m. One species, P. sequeirae n. sp., is a narrow endemic found only at timberline in the Agulhas Negras massif above 2300 m. Immature stages are described for two species, P. phanias and P. landryi n. sp. Molecular data (barcode region of cytochrome oxidase, subunit I) and adult morphology, including male and female genitalia, support the genus as monophyletic, belonging to a predominantly Andean clade of the Pedaliodes Butler, 1867 complex. Morphological evidences, in particular female genitalia comparative analysis, indicate the genera Physcopedaliodes Forster, 1964 and Panyapedaliodes Forster, 1964 as possibly the closest relatives to Praepedaliodes. Molecular data are inconclusive in this respect.     

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.     

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.     

A global survey of <Emphasis Type="Italic">Puccinia</Emphasis>-rust on Cucurbitaceae

In this paper, all known autoecious Puccinia species (rust fungi, Uredinales) on Cucurbitaceae are described and most of them illustrated. A key and information on their host range and distribution is presented. Four species, Puccinia antennata, P. arbor-miraculensis, P. hieroglyphica, and P. rhytidioderma are proposed as new. P. momordicae and P. trochomeriae are recognised as valid species different from P. cephalandrae. Uredo melothriae is a new combination for Uromyces melothriae. P. cucumeris is a new report for Namibia, P. momordicae for Zimbabwe and P. vanderystii for Kenya. The species appear to be host specific with regard to host tribes, but P. citrulli and P. cucumeris may pass tribal boundaries. Most species are morphologically very similar and are characterised by a unique set of teliospore characters. They are therefore regarded as a natural group. The distribution of this group in semiarid habitats, mainly from southern Africa to India, is discussed.     

Morphological and molecular data for a new species of <Emphasis Type="Italic">Pomphorhynchus</Emphasis> Monticelli, 1905 (Acanthocephala: Pomphorhynchidae) in the Mexican redhorse <Emphasis Type="Italic">Moxostoma austrinum</Emphasis> Bean (Cypriniformes: Catostomidae) in central Mexico

Pomphorhynchus purhepechus n. sp. is described from the intestine of the Mexican redhorse Moxostoma austrinum Bean (Catostomidae) in central Mexico. The new species can be distinguished from the other seven described species of Pomphorhynchus Monticelli, 1905 in the Americas by a subspherical proboscis and 14 longitudinal rows with 16–18 hooks each; the third and the fourth row of hooks are alternately longest. Sequences of the mitochondrial cytochrome c oxidase subunit 1 (cox1) gene and the large subunit (LSU) rDNA (including the domains D2-D3) were used to corroborate the morphological distinction between the new species and Pomphorhynchus bulbocolli Linkins in Van Cleave, 1919, a species widely distributed in several freshwater fish species across Canada, USA, and Mexico. The genetic divergence estimated between the new species and the isolates of P. bulbocolli ranged between 13 and 14% for cox1, and between 0.6 and 0.8% for LSU. Maximum likelihood and Bayesian inference analyses of each dataset showed that the isolates of P. bulbocolli parasitising freshwater fishes from three families, the Catostomidae, Cyprinidae and Centrarchidae, represent a separate lineage, and that the acanthocephalans collected from two localities in central Mexico comprise an independent lineage. In addition, our analysis of the genetic variation of P. bulbocolli demonstrates that individuals of this acanthocephalan from different host species are conspecific. Finally, the distribution, host-association, and phylogenetic relationship of the new species, when placed in the context of the region’s geological history, suggest that both host and parasite underwent speciation after their ancestors became isolated in Central Mexico.     

A New record of four <Emphasis Type="Italic">Penicillium</Emphasis> species isolated from <Emphasis Type="Italic">Agarum clathratum</Emphasis> in Korea

Agarum clathratum, brown algae, play important ecological roles in marine ecosystem, but can cause secondary environment pollution when they pile up on the beach. In order to resolve the environment problem by A. clathratum, we focus to isolate and identify Penicillium because many species are well known to produce extracellular enzymes. A total of 32 Penicillium strains were isolated from A. clathratum samples that collected from 13 sites along the mid-east coast of Korea in summer. They were identified based on morphological characters and phylogenetic analysis using β-tubulin DNA sequences as well as a combined dataset of β-tubulin and calmodulin. A total of 32 strains were isolated and they were identified to 13 Penicillium species. The commonly isolated species were Penicillium citrinum, P. roseomaculatum, and Penicillium sp. Among 13 Penicillium species, four species – P. bilaiae, P. cremeogriseum, P. madriti, and P. roseomaculatum – have not been previously recorded in Korea. For these four new species records to Korea, we provide morphological characteristics of each strain.     

Karyological features of the genus <Emphasis Type="Italic">Planorbarius</Emphasis> (Gastropoda,Pulmonata, Bulinidae) of the Ukrainian fauna

The absence of significant distinctions between the species of the genus Planorbarius in the narrow sense (P. corneus, P. banaticus, P. purpura, and P. grandis) has been established. All investigated species had identical chromosomal formulas (2n = 30m + 6sm = 36) and fundamental numbers (FN = 72). Reproducible distinctions between them were not found by total complement length (TCL), relative length of chromosomes (RL), and centromeric indexes. The species selected on the basis of genetic marking differed clearly by centromeric index of chromosome 12, which confirms the allospecies frame of P.corneus s. lato.     

The species composition and ecological features of pea crabs of the genus <Emphasis Type="Italic">Pinnixa</Emphasis> White, 1846 (Brachyura: Pinnotheridae) in Peter the Great Bay,the Sea of Japan

This paper provides an overview of pea crabs of the genus Pinnixa White, 1846 (Brachyura: Pinnotheridae) that occur along the Russian coast of the Sea of Japan. Three species of the genus have been recorded for this area: P. tumida Stimpson, 1858, P. rathbuni Sakai, 1934, as well as P. banzu Komai, Nishi & Taru, 2014, which is the first record for the fauna of Russia. All species clearly differ ecologically: P. tumida was found in Posyet Bay in the intestine of the burrowing holothurian Paracaudina chilensis (Müller, 1850); P. rathbuni, in burrows of the echiuroid Urechis unicinctus (von Drasche, 1881); and P. banzu, in tubes of the polychaete Chaetopterus cautus Marenzeller, 1879. The paper also provides a definitive key to Pinnixa species and data on the size, behavior, symbionts, and parasites of P. rathbuni and P. banzu.
