Taxonomy and multi-gene phylogeny of Micropsalliota (Agaricales, Agaricaceae) with description of six new species from China.

ABSTRACT: Micropsalliota is a relatively small genus containing only 62 previously identified species. Here, we describe six new taxa of Micropsalliota based on morphological and phylogenetic analyses: M. minor, M. ovalispora, M. pseudodelicatula, M. rufosquarrosa, M. tenuipes, and M. wuyishanensis and a new record taxon to China. The first Maximum likelihood and Bayesian analyses of a three-gene dataset (ITS, LSU, and rpb2) separated the genus into 18 weakly to strongly supported major clades and subclades, but only a few subclades were synapomorphies. According to phylogenetic analyses, M. cornuta does not belong in Micropsalliota. A key to 20 species of Micropsalliota in China is provided.

Taxonomy and Multi-Gene Phylogeny of Poroid Panellus (Mycenaceae, Agaricales) With the Description of Five New Species From China.

Project description:Panellus is an Agaricales genus with both lamellate and poroid hymenophore. The poroid species are readily overlooked because of their tiny basidiocarps. The Chinese samples of poroid Panellus are studied, and five species, namely Panellus alpinus, Panellus crassiporus, Panellus longistipitatus, Panellus minutissimus, and Panellus palmicola are described as new species based on morphology and molecular phylogenetic analyses inferred from an nrITS dataset and a multi-gene dataset (nrITS + nrLSU + mtSSU + nrSSU + tef1). Panellus alpinus is characterized by its round to ellipsoid pores measuring 4-6 per mm and oblong ellipsoid basidiospores measuring 4.8-6 μm × 2.8-3.6 μm; P. crassiporus differs from other poroid species in the genus by the irregular pores with thick dissepiments and globose basidiospores measuring 8-9.8 μm × 6.9-8 μm; P. longistipitatus is distinguished by its long stipes, pyriform cheilocystidia, and broadly ellipsoid to subglobose basidiospores measuring 7-9.8 μm × 5-7 μm; P. minutissimus is characterized by its tiny and gelatinous basidiocarps, 5-20 pores per basidiocarp, and ellipsoid basidiospores measuring 6-8 μm × 3.2-4.2 μm; P. palmicola is characterized by its round pores measuring 2-4 per mm, the presence of acerose basidioles, and globose basidiospores measuring 7-9.5 μm × 6.2-8.2 μm. An identification key to 20 poroid species of Panellus is provided.

Taxonomy and Phylogeny of Cystolepiota (Agaricaceae, Agaricales): New Species, New Combinations and Notes on the C. seminuda Complex.

Project description:Species of Cystolepiota are known as diminutive lepiotaceous fungi with a worldwide distribution. Previous studies revealed that Cystolepiota is not monophyletic and preliminary DNA sequence data from recent collections suggested that several new species exist. Based on multi-locus DNA sequence data (the nuc rDNA internal transcribed spacer region ITS1-5.8S-ITS2, ITS; the D1-D2 domains of nuc 28S rDNA, LSU; the most variable region of the second-largest subunit of RNA polymerase II, rpb2 and a portion of the translation-elongation factor 1-α. tef1), C. sect. Pulverolepiota forms a distinct clade separating from Cystolepiota. Therefore, the genus Pulverolepiota was resurrected and two combinations, P. oliveirae and P. petasiformis were proposed. With the integration of morphological characteristics, multi-locus phylogeny, and information on geography and habitat, two new species, viz. C. pseudoseminuda and C. pyramidosquamulosa, are described and C. seminuda was revealed to be a species complex containing at least three species, viz. C. seminuda, C. pseudoseminuda, and Melanophyllum eryei. In addition, C. seminuda was re-circumscribed and neo-typified based on recent collections.

Two new species of Micropsalliota (Agaricales, Agaricaceae) from subtropical regions of China.

Project description:Micropsalliota is a relatively small genus, with 97 names recorded in previous research. In this study, two new species of Micropsalliota, M.bispora and M.vulgaris, have been identified based on morphological and phylogenetic evidence from subtropical regions of China. Morphologically, M.bispora is characterized by very small basidiomata, cymbiform basidiospores up to 9.0 μm long, white to cream pileus with fawn to dull red center, and tibiiform cheilocystidia; M.vulgaris is recognized by small basidiomata, medium-sized spores, white to cream pileus, covered with reddish brown to dark brown fibrils, various cheilocystidia that are up to 60 μm long, and hyphae of fibrils exhibiting pale brown vacuolar pigmentation. Their distinct taxonomic status is confirmed by the positions of the two new species in 4-locus (ITS, LSU, rpb2, tef-1α) phylogenetic trees. Detailed descriptions and morphological photographs of two new species are presented. To aid in diagnosis, a key to 35 species of Micropsalliota in China is provided.

Two new species of genus Leucoagaricus (Agaricaceae, Agaricales) from Pakistan.

Project description:The genus of basidiomycetous fungi, Leucoagaricus, occurs worldwide, from subtropical to boreal latitudes. Several collections of Leucoagaricus were made during mycological field trips conducted in different forests of Margalla, Pakistan. An integrative framework combining morphological and phylogenetic data was employed for their study. As a result, the two species La.margallensis and La.glareicolor are here described as new to science. Detailed macro- and micro-morphological descriptions, and a molecular phylogenetic reconstruction based on nrITS and LSU sequence data are provided and used to discriminate the new species from morphologically and phylogenetically close taxa. Whereas, our phylogenetic tree inference gave unequivocal support for the inclusion of these two species within the section Leucoagaricus.

Taxonomy and Phylogeny of Cystostereaceae (Agaricales, Basidiomycota): A New Genus, Five New Species, and Three New Combinations.

Project description:This paper aims to understand the species diversity, taxonomy, and phylogeny of Cystostereaceae (Agaricales), which is based primarily on material from East and Southeast Asia. Cystostereaceae is a small, understudied family of saprobes of woody plants with a worldwide distribution. Phylogenetic analyses of the LSU and ITS sequences revealed four distinct clades in the Cystostereaceae, representing the genera Crustomyces, Cystostereum, Effusomyces gen. nov., and Parvodontia. In addition, phylogenetic analyses showed that Cystidiodontia and Rigidotubus are synonyms of Crustomyces for their type of species nested within the Crustomyces clade. The new monotypic genus Effusomyces, based on specimens from Thailand, lacks any distinctive morphological features. Parvodontia, originally erected for a species from South America, is reported for the first time from Asia. The widely distributed and morphologically well-characterized Cystostereum is represented in East Asia by two new species: Cystostereum crassisporum and C. submurrayi. In addition, three new species, viz., Crustomyces albidus, Effusomyces thailandicus, and Parvodontia austrosinensis, are described and illustrated. Finally, three new combinations are proposed: Crustomyces isabellinus, C. laminiferus, and C. tephroleucus. A key to the genera and species of Cystostereaceae is provided. Our results proved that the species diversity of wood-decaying fungi in East and Southeast Asia is rich and suggested that more investigations and studies should be carried out in the future.

Taxonomy and phylogeny of the Leptographium olivaceum complex (Ophiostomatales, Ascomycota), including descriptions of six new species from China and Europe.

Project description:The Leptographium olivacea complex encompasses species in the broadly defined genus Leptographium (Ophiostomatales, Ascomycota) that are generally characterized by synnematous conidiophores. Most species of the complex are associates of conifer-infesting bark beetles in Europe and North America. The aims of this study were to reconsider the delineation of known species, and to confirm the identity of several additional isolates resembling L. olivacea that have emerged from recent surveys in China, Finland, Poland, Russia, and Spain. Phylogenetic analyses of sequence data for five loci (ACT, TUB, CAL, ITS2-LSU, and TEF-1α) distinguished 14 species within the complex. These included eight known species (L. cucullatum, L. davidsonii, L. erubescens, L. francke-grosmanniae, L. olivaceum, L. olivaceapini, L. sagmatosporum, and L. vescum) and six new species (herein described as L. breviuscapum, L. conplurium, L. pseudoalbum, L. rhizoidum, L. sylvestris, and L. xiningense). New combinations are provided for L. cucullatum, L. davidsonii, L. erubescens, L. olivaceum, L. olivaceapini, L. sagmatosporum and L. vescum. New Typifications: Lectotypes are designated for L. olivaceum, L. erubescens and L. sagmatosporum. Epitypes were designated for L. olivaceapini and L. sagmatosporum. In addition to phylogenetic separation, the synnematous asexual states and ascomata with almost cylindrical necks and prominent ostiolar hyphae, distinguish the L. olivaceum complex from others in Leptographium.

A multi-gene phylogeny of Chlorophyllum (Agaricaceae, Basidiomycota): new species, new combination and infrageneric classification.

Project description:Taxonomic and phylogenetic studies of Chlorophyllum were carried out on the basis of morphological differences and molecular phylogenetic analyses. Based on the phylogeny inferred from the internal transcribed spacer (ITS), the partial large subunit nuclear ribosomal DNA (nrLSU), the second largest subunit of RNA polymerase II (rpb2) and translation elongation factor 1-α (tef1) sequences, six well-supported clades and 17 phylogenetic species are recognised. Within this phylogenetic framework and considering the diagnostic morphological characters, two new species, C. africanum and C. palaeotropicum, are described. In addition, a new infrageneric classification of Chlorophyllum is proposed, in which the genus is divided into six sections. One new combination is also made. This study provides a robust basis for a more detailed investigation of diversity and biogeography of Chlorophyllum.

Taxonomy and Phylogeny of Meruliaceae with Descriptions of Two New Species from China.

Project description:Two new wood-inhabiting fungi Hermanssonia fimbriata sp. nov. and Phlebia austroasiana sp. nov. in the Meruliaceae family are described and illustrated from southwestern China based on molecular and morphological evidence. The characteristics of H. fimbriata include annual, resupinate basidiomata, the absence of cystidia and cystidioles, oblong ellipsoid basidiospores of 5-6 × 2.4-3 μm, and growth on rotten gymnosperm wood in the east Himalayas. Its basidiomata change drastically upon drying, from being a light-coloured, juicy, papillose-to-wrinkled hymenophore, to a dark-coloured, corky-to-gelatinous, and more or less smooth hymenophore. The characteristics of Ph. austroasiana include annual, resupinate basidiomata, a hydnoid hymenophore, 2-3 spines per mm, the presence of tubular cystidia of 20-25 × 3-3.5 µm, oblong ellipsoid basidiospores of 4.4-5.2 × 2.1-3 μm, and growth on angiosperm wood in tropical forests in the southern Yunnan Province. The phylogenetic analyses based on the combined 2-locus dataset (ITS1-5.8S-ITS2 (ITS) + nuclear large subunit RNA (nLSU)) confirm the placement of two new species, respectively, in Hermanssonia and Phlebia s. lato. Phylogenetically, the closely-related species to these two new species are discussed.

Molecular phylogeny and taxonomy of the remarkable genus Leptoporus (Polyporales, Basidiomycota) with description of a new species from Southwest China.

Project description:Leptoporus is a rare and remarkable genus, mainly occurring in coniferous forests in the Northern Hemisphere. Recent phylogenetic studies showed that Leptoporus belongs to Irpicaceae in the phlebioid clade. It is worth noting that most species in the phlebioid clade can cause white-rot decay, except for the Leptoporus species, which can cause a brown-rot decay. In this study, we performed phylogenetic and taxonomic studies of Leptoporus and related genera. Molecular phylogenetic analyses were conducted based on sequences from multiple loci including the internal transcribed spacer (ITS) regions, the large subunit of nuclear ribosomal RNA gene (nLSU), the largest subunit of RNA polymerase II gene (RPB1), the second largest subunit of RNA polymerase II gene (RPB2), and the translation elongation factor 1-α gene (TEF1). Combined with morphological characteristics, a new species, Leptoporus submollis sp. nov., is discovered and illustrated from Southwest China.
