<Emphasis Type="Italic">Cantharellus</Emphasis> sect. <Emphasis Type="Italic">Amethystini</Emphasis> in Asia

In this contribution on the genus Cantharellus in Asia, C. subvaginatus is described from the Republic of Korea as a close relative to the Chinese C. vaginatus, which is here reported for the first time from India. Both species are here placed in Cantharellus subg. Cantharellus sect. Amethystini, together with the Indian C. pseudoformosus (syn.: C. umbonatus) and the Malayan C. subamethysteus. As such, Asia has suddenly become the continent with the highest diversity for Amethystini. Species delimitation in sect. Amethystini is molecularly supported by a combined phylogenetic analysis of rDNA sequences obtained for LSU and ITS and additionally suggests the existence of a still undescribed species in North America. Character variability is discussed for all known members of Amethystini, including atypical specimens of the North American C. lewisii that are morphologically more reminiscent of the South Korean C. subvaginatus.     

<Emphasis Type="Italic">Phylloporia minutipora and P. radiata</Emphasis> spp. nov. (Hymenochaetales,Basidiomycota) from China and a key to worldwide species of <Emphasis Type="Italic">Phylloporia</Emphasis>

Phylloporia is a monophyletic genus within the Hymenochaetaceae as recovered by nuclear large subunit ribosomal DNA (nLSU) sequences. According to the summarization of 38 species accepted in this genus, Phylloporia is characterized by an absence of setae and the presence of abundant thick-walled, colored and tiny basidiospores, although its other morphological characters are highly diverse. Nine herbarium specimens from China, fitting the morphological concept of Phylloporia, were morphologically and phylogenetically studied in detail. The phylogeny inferred from nLSU sequences shows that the nine specimens formed three terminal lineages within the Phylloporia clade. Two lineages being composed of four specimens from Hainan and three from Guizhou were newly described as Phylloporia minutipora and P. radiata, respectively. In Phylloporia, P. minutipora is distinct by a combination of annual, sessile and imbricate basidiocarps, distinctly concentrically sulcate pileal surface with obtuse margin, angular pores of 12–15 per mm, duplex context separated by a black zone, a dimitic hyphal system, and broadly ellipsoid basidiospores of 2.5–3?×?2–2.5 μm, while P. radiata is distinct by a combination of annual, sessile and imbricate basidiocarps, faintly sulcate and radially striate pileal surface, sharp pileal margin, angular pores of 8–10 per mm, duplex context separated by a black zone, a monomitic hyphal system, and broadly ellipsoid basidiospores of 2.5–3.5?×?2–2.5 μm. The third lineage, comprising two specimens from Hainan, was morphologically determined as Phylloporia pulla. This species was recently combined to Phylloporia based on only morphological characters, and the current study for the first time generated its molecular sequences for phylogenetic reference. A key to all 40 species of Phylloporia is provided.     

More white verticillium-like anamorphs with erect conidiophores

This study focuses on the former Verticillium section Albo-erecta that included white or whitish species with verticillium-like, erect conidiophores. Its type species was Verticillium fungicola, which was transferred to Lecanicillium, a genus that otherwise contains species with prostrate conidiophores. Phylogenetic analysis of ITS, 18S and 28S rDNA sequences revealed that this group is heterogeneous and its members belong to at least three families. The present study is a first step to its resolution. Supported by analyses of 68 sequences of ITS, 23 sequences of 18S and 43 sequences of 28S ribosomal DNA, the species are distributed over three families. In the Cordycipitaceae, Leptobacillium gen. nov. is described with L. leptobactrum comb. nov. and its new variety, calidius. In the Hypocreaceae, Hypomyces is treated with one new combination from former Nectriopsis, H. tubariicola, and two new anamorphic species, H. ellipsosporus and H. subglobosus; in Sphaerostilbella, one new anamorphic species, S. parabroomeana, is described. In the Bionectriaceae, anamorphic isolates of Nectriopsis requiring a new combination, N. lindauiana, and a new species, N. fuliginicola, are described. Parsimony analysis of the LSU suggests that Ovicillium gen. nov. with four new species, O. attenuatum, O. oosporum, O. subglobosum and O. napiforme, is a member of the Bionectriaceae by 93 % bootstrap support. Of uncertain family classification are Chlamydocillium gen. nov. with one new soil-borne species, C. cyanophilum, and Chlorocillium gen. nov. based on Acremonium griseum Petch. A few further white verticillium-like anamorphs, particularly V. biguttatum, could not yet be reclassified.     

<Emphasis Type="BoldItalic">Barrmaelia</Emphasis> and <Emphasis Type="BoldItalic">Entosordaria</Emphasis> in Barrmaeliaceae (fam. nov., Xylariales) and critical notes on <Emphasis Type="BoldItalic">Anthostomella</Emphasis>-like genera based on multigene phylogenies

Phylogenetic analyses of a combined DNA data matrix containing ITS, LSU, rpb2 and tub2 sequences of representative Xylariales revealed that the genus Barrmaelia is a well-defined monophylum, as based on four of its described species (B. macrospora, B. moravica, B. oxyacanthae, B. rhamnicola) and the new species B. rappazii. The generic type of Entosordaria, E. perfidiosa, is revealed as the closest relative of Barrmaelia, being phylogenetically distant from the generic type of Clypeosphaeria, C. mamillana, which belongs to Xylariaceae sensu stricto. Entosordaria and Barrmaelia are highly supported and form a distinct lineage, which is recognised as the new family Barrmaeliaceae. The new species E. quercina is described. Barrmaelia macrospora, B. moravica and B. rhamnicola are epitypified and E. perfidiosa is lecto- and epitypified. Published sequences of Anthostomella and several Anthostomella-like species from the genera Alloanthostomella, Anthostomelloides, Neoanthostomella, Pseudoanthostomella and Pyriformiascoma are evaluated, demonstrating the necessity of critical inspection of published sequence data before inclusion in phylogenies. Verified isolates of several species from these genera should be re-sequenced to affirm their phylogenetic affinities. In addition, the generic type of Anthostomella should be sequenced before additional generic re-arrangements are proposed.     

Distribution of arbuscular mycorrhizal fungi in four semi-mangrove plant communities

To better understand the diversity and species composition of arbuscular mycorrhizal fungi (AMF) in mangrove ecosystems, the AMF colonization and distribution in four semi-mangrove plant communities were investigated. Typical AMF hyphal, vesicle and arbuscular structures were commonly observed in all the root samples, indicating that AMF are important components on the landward fringe of mangrove habitats. AMF spores were extracted from the rhizospheric soils, and an SSU rDNA fragment from each spore morph-type was amplified and sequenced for species identification. AMF species composition and diversity in the roots of each semi-mangrove species were also analyzed based on an SSU-ITS-LSU fragment, which was amplified, cloned and sequenced from root samples. In total, 11 unique AMF sequences were obtained from spores and 172 from roots. Phylogenetic analyses indicated that the sequences from the soil and roots were grouped into 5 and 14 phylotypes, respectively. AMF from six genera including Acaulospora, Claroideoglomus, Diversispora, Funneliformis, Paraglomus, and Rhizophagus were identified, with a further six phylotypes from the Glomeraceae family that could not be identified to the genus level. The AMF genus composition in the investigated semi-mangrove communities was very similar to that in the intertidal zone of this mangrove ecosystem and other investigated mangrove ecosystems, implying possible fungal adaptation to mangrove conditions.     

European <Emphasis Type="Italic">Hodophilus</Emphasis> (Clavariaceae,Agaricales) species with yellow stipe

Phylogenetic reconstruction of Hodophilus species with a yellow colour on the stipe based on nrITS, nrLSU and rpb2 sequences revealed six European species. All these species correspond to the widely accepted European concept of a single species Hodophilus micaceus. Four of these species are described and illustrated. H. micaceus and H. phaeoxanthus are recognised as two separate species and H. albofloccipes as a synonym of the latter. Two species, H. anatinus and H. cambriensis, are described as new. Possible endemism of H. micaceus and H. cambriensis to the British Isles is discussed. All analysed North American samples represent different species to those found in Europe. The North American species Hygrophorus rugulosus is combined in the genus Hodophilus. The preliminary key uses position and development of the yellow colour during maturation as the most important distinguishing character. The presence of the yellow colour is discussed as a possible synapomorphic character.     

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.     

Relationships within <Emphasis Type="Italic">Capitotricha bicolor</Emphasis> (Lachnaceae,Ascomycota) as inferred from ITS rDNA sequences,including some notes on the <Emphasis Type="Italic">Brunnipila</Emphasis> and <Emphasis Type="Italic">Erioscyphella</Emphasis> clades

DNA sequences of Capitotricha bicolor from Quercus, Fagus sylvatica, Alnus alnobetula, and Nothofagus, and C. rubi from Rubus idaeus were obtained from apothecia to establish whether specimens from different hosts belong to separate species. The obtained ITS1–5.8S–ITS2 rDNA sequences were examined with Bayesian and parsimony phylogenetic analyses. Intra- and interspecific variation was also investigated based on molecular distances in the ITS region. The phylogenetic analyses supported the specific distinctness of Capitotricha rubi and the Capitotricha from Nothofagus, but also suggest specific distinctness between samples from Quercus, Fagus, and Alnus. The interspecific distances were larger than intraspecific distances for all examined units. The smallest distance was found between the “Alnus alnobetula” and “Fagus sylvatica” units. Two new sequences of Brunnipila are published. Capitotricha, Lachnum, and Erioscyphella are compared to each other based on hair and excipulum characteristics.     

Composition and diversity of the bacterial community in snow leopard (<Emphasis Type="Italic">Uncia uncia</Emphasis>) distal gut

Intestinal microflora influences many essential metabolic functions, and is receiving increasing attention from the scientific community. However, information on intestinal microbiota, especially for large wild carnivores, is insufficient. In the present study, the bacterial community in the feces of snow leopards (Uncia uncia) was described based on 16S rRNA gene sequence analysis. A total of 339 near-full-length 16S rRNA gene sequences representing 46 non-redundant bacterial phylotypes (operational taxonomical units, OTUs) were identified in fecal samples from four healthy snow leopards. Four different bacterial phyla were identified: Firmicutes (56.5 %), Actinobacteria (17.5 %), Bacteroidetes (13 %), and Proteobacteria (13 %). The phylum Actinobacteria was the most abundant lineage, with 40.4 % of all identified clones, but Clostridiales, with 50 % of all OTUs, was the most diverse bacterial order. The order Clostridiales was affiliated with four families: Clostridiaceae I, Lachnospiraceae, Peptostreptococcaceae, and Ruminococcaceae. Lachnospiraceae was the most diverse family with 17 OTUs identified. These findings were basically consistent with previous reports on the bacterial diversity in feces from other mammals.     

Genetic analysis of Japanese and American specimens of <Emphasis Type="Italic">Scirpus hattorianus</Emphasis> suggests its introduction from North America

Scirpus hattorianus is a possible alien species in Japan, and a clarification of its unclear taxonomy is required to reveal its origin. It is not known whether the plants initially described from Japan represent the same species distributed in North America. To clarify the origin of the species, we attempted to sequence old specimens collected about 80 years ago using newly designed primer pairs specific for short sequences, including the variable sites. Chloroplast sequences of ndhF were compared among Japanese and North American S. hattorianus, and the closely related species, S. atrovirens, S. flaccidifolius, and S. georgianus. We succeeded in sequencing all samples, and two haplotypes were detected in S. hattorianus: one was unique to the species and the other, detected from specimens potentially collected from the same population as the types, was shared by both North American S. hattorianus and two closely related species, S. atrovirens and S. flaccidifolius. Our results suggest that Japanese S. hattorianus is an alien species that was introduced from North America at least twice.     

Taxonomy and phylogeny of <Emphasis Type="Italic">Cryptocoryneum</Emphasis> (Pleosporales,Dothideomycetes)

Species of Cryptocoryneum were taxonomically reassessed on the basis of morphological observations and the results of molecular phylogenetic analysis. Eighteen isolates of Cryptocoryneum species, namely two strains from Africa, three from Europe, and 13 from Japan, were phylogenetically analysed using sequences of nuclear rDNA internal transcribed spacers (ITS) and the partial sequence of the translation elongation factor 1α gene (TEF1). The phylogenetic analysis indicated that Cryptocoryneum species formed a monophyletic clade and were closely related to Lophiotrema (Lophiotremataceae) and Aquasubmersa (incertae sedis) in the Pleosporales (Dothideomycetes). We examined holotype specimens of C. fasciculatum, C. hysterioides, and Torula uniformis and concluded that these species are conspecific, with C. hysterioides having priority. Although C. hysterioides has long been regarded as a synonym of C. condensatum, we consider C. hysterioides to be a distinct species within the genus. We found several cryptic species that were morphologically similar to C. condensatum sensu lato, but that could be separated on the basis of conidial size and the number of conidial arms and conidial septa, characters that seem to be informative for species delimitation within Cryptocoryneum. A total of seven new species, namely C. akitaense, C. brevicondensatum, C. congregatum, C. japonicum, C. longicondensatum, C. paracondensatum, and C. pseudorilstonei, are described and illustrated. A key to species accepted in Cryptocoryneum is provided.     

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.     

Notes on <Emphasis Type="Italic">Teskeyellus</Emphasis> Philip &amp; Fairchild (Diptera: Tabanidae: Diachlorini) and Description of <Emphasis Type="Italic">T</Emphasis>. <Emphasis Type="Italic">cyanommatus</Emphasis> Sp. Nov., a Non-blood Sucking Horsefly from the Amazon Basin

The monotypic genus Teskeyellus was described for T. hirsuticornis Philip & Fairchild 1974, from Mexico. After more than 40 years, another species is described in the genus, T. cyanommatus sp. nov., based on two females and one male specimens from Amazon basin. The type specimens of T. hirsuticornis were studied and we concluded that there are enough similarities to include the new species in Teskeyellus.     

<Emphasis Type="Italic">Helicocollum</Emphasis>, a new clavicipitalean genus pathogenic to scale insects (Hemiptera) in Thailand

A new genus pathogenic to scale insects (Coccidae, Hemiptera), Helicocollum, is described from Thailand. It includes the three species, H. chanthaburiensis, H. krabiensis and H. surathaniensis. Phylogenetic inferences on the basis of partial sequences of the large subunit of the nuclear ribosomal DNA, translation elongation factor 1-α and RNA polymerase II subunit 1 place the new genus in the Clavicipitaceae, although morphological features of the phialides resemble Hirsutella in the Ophiocordycipitaceae. Within the Clavicipitaceae, Helicocollum is closely related to Aschersonia, Moelleriella, Regiocrella, and Samuelsia, all known as pathogens of scale insects. Helicocollum differs from other scale insect pathogens in having phialides with helical necks and synnematous or sporodochial conidiomata, but pycnidia. Morphological characteristics are evaluated and compared with other asexual morphs producing twisted, undulated phialidic necks or occurring on scale insects.     

The species of <Emphasis Type="Italic">Lentaria</Emphasis> (Gomphales,Basidiomycota) from China based on morphological and molecular evidence

Lentaria Corner is a widespread basidiomycetous genus composed of 17 known species. Most members of this genus are lignicolous and play important roles as decomposers in forest ecosystems. Lentaria specimens collected from China were studied using morphological and molecular methods. Five species were recognized, two of which, L. bambusina and L. uncispora, were described as new species. In addition, L. patouillardii was confirmed to be a new record from China. The remaining two species, L. byssiseda and L. surculus, were previously found in China. The two new species were described in detail, illustrated with line drawings and photographs, and compared with similar species. The other three species were redescribed to clarify their morphological characters and distribution patterns. Phylogeny of this genus was analyzed based on internal transcribed spacer sequences. Additionally, a key to Lentaria species in China is provided. Holotypes of the two new species are deposited in the Mycological Herbarium of Hunan Normal University.     

Novel <Emphasis Type="Italic">Collophorina</Emphasis> and <Emphasis Type="Italic">Coniochaeta</Emphasis> species from <Emphasis Type="Italic">Euphorbia polycaulis</Emphasis>, an endemic plant in Iran

During a study on the biodiversity of yeasts and yeast-like ascomycetes from wild plants in Iran, four strains of yeast-like filamentous fungi were isolated from a healthy plant of Euphorbia polycaulis in the Qom Province, Iran (IR. of). All four strains formed small hyaline one-celled conidia from integrated conidiogenous cells directly on hyphae and sometimes on discrete phialides, as well as by microcyclic conidiation. Two strains additionally produced conidia in conidiomata that open by rupture. The internal transcribed spacer (ITS) sequences suggested the placement of these strains in the genera Collophorina (Leotiomycetes) and Coniochaeta (Sordariomycetes), respectively. Blast search results on NCBI GenBank and phylogenetic analyses of ITS, the glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and the translation elongation factor 1α (EF-1α) sequences, and the nuclear large subunit ribosomal gene (LSU), partial actin (ACT), and β-tubulin (TUB) sequences, respectively, revealed the isolates to belong to three new species, that are described here as Collophorina euphorbiae, Coniochaeta iranica, and C. euphorbiae. All three species are characterised by morphological, physiological, and molecular data.
