A new species of the genus Aleurodiscus sensu lato (Russulales, Basidiomycota) from Hachijo Island, Japan.

ABSTRACT: Aleurodiscus sagittisporus sp. nov. is described and illustrated. This species is characterized by producing basidiomata with a monomitic hyphal system, clampless-septate hyphae, arrowhead-shaped, amyloid, finely verrucose basidiospores, gloeocystidia, dendrohyphidium-like branched paraphysoid hyphae, and variously shaped swelling cells in the hymenium. Phylogenetic analyses based on nuclear rDNA LSU and ITS sequences revealed that the species is distinct from the lineage of Aleurodiscus s. str. and related genera in the Aleurodiscus s. lat. clade. Basidiomata of A. sagittisporus have been collected only from dead petioles attached to living trees of Livistona chinensis var. subglobosa on Hachijo Island, Japan.

Hypochnicium sensu lato (Polyporales, Basidiomycota) from Japan, with descriptions of a new genus and three new species.

Project description:Species of Hypochnicium (Polyporales, Basidiomycota) collected from Japan were studied on their taxonomy by morphological and phylogenetic approaches. Phylogenetic analyses based on a nrDNA LSU and ITS dataset including the Japanese specimens and other publicly available ones show that Hypochnicium is polyphyletic. Since the clade containing the type species H. bombycinum was well-supported, we defined this clade as Hypochnicium s. str., and emended Hypochnicium to include restricted taxa with only smooth basidiospores. The new genus Neohypochnicium is proposed to accommodate the remaining taxa excluded from the genus Hypochnicium s. str., which includes both species with smooth basidiospores and ornamented ones. Three new species, Gyrophanopsis japonica, N. asiaticum and N. perlongicystidiosum are described and illustrated based on morphological and phylogenetic analyses using an ITS region dataset. In addition, the following 15 new combinations are proposed: N. albostramineum, N. aotearoae, N. capitulateum, N. cremicolor, N. cystidiatum, N. geogenium, N. guineense, N. huinayense, N. michelii, N. microsporum, N. patagonicum, N. pini, N. punctulatum, N. subrigescens and N. wakefieldiae. An identification key to Japanese species of Bulbillomyces, Gyrophanopsis, Hypochnicium and Neohypochnicium is provided.

Taxonomy and phylogeny of Resinicium sensu lato from Asia-Pacific revealing a new genus and five new species (Hymenochaetales, Basidiomycota).

Project description:Resinicium, belonging to Hymenochaetales, Agaricomycetes, is a worldwide genus of corticioid wood-inhabiting fungi. To improve the knowledge of species diversity within the Hymenochaetales, two dozen specimens from Asia-Pacific preliminarily identified to be members of Resinicium sensu lato were carefully studied from morphological and phylogenetic perspectives. From these specimens, a new monotypic genus Skvortzoviella, and five new species, viz. Resinicium austroasianum, R. lateastrocystidium, Skvortzovia dabieshanensis, S. qilianensis and Skvortzoviella lenis are described; moreover, a new basal lineage of Resinicium represented by a Vietnam specimen and three Chinese specimens of S. pinicola are identified. The six newly proposed taxa are morphologically compared with related genera and species, while the family positions of Resinicium, Skvortzovia, and Skvortzoviella within the Hymenochaetales are still ambiguous. In addition, the ancestral geographic origin of Resinicium, even though inconclusive, is now thought to be Asia-Pacific instead of tropical America as previously assumed.

Species diversity and taxonomy of Scytinostroma sensu stricto (Russulales, Basidiomycota) with descriptions of four new species from China.

Project description:Scytinostroma is species-rich genus in Peniophoraceae, Russulales and has been shown to be polyphyletic. In this study, we performed phylogenetic analyses on the core clade of Scytinostroma based on concatenated ITS1-5.8S-ITS2-nrLSU sequence data. Fifteen lineages including four new species from China, Scytinostromabeijingensis, S.boidinii, S.subduriusculum, and S.subrenisporum, were recognized. The genus Michenera was nested within the Scytinostroma s.s. clade in the phylogenetic tree of Peniophoraceae. Sequences of S.portentosum (type species) and S.hemidichophyticum from Europe formed a strongly supported lineage sister to the S.portentosum sample from Canada. It is supposed that the European "S.portentosum" is S.hemidichophyticum, and the former species is restricted in distribution to North America. Scytinostromaduriusculum is supposed to be a species complex. Samples from Sri Lanka (the type locality) formed a lineage sister to those from China, Thailand and Vietnam (described herein as S.subduriusculum) and two samples from France that might represent an undescribed species. The four new species are described and illustrated, and an identification key to all the 14 Scytinostroma s.s. species worldwide is provided. Until now, seven species of Scytinostroma s.s. have been found in China. Our results increased the knowledge of species diversity and taxonomy of corticioid fungi in China.

Two new species of Exidia sensu lato (Auriculariales, Basidiomycota) based on morphology and DNA sequences.

Project description:In the present study, fourteen Exidia-like specimens were collected from China, France, and Australia. Based on morphological characteristics and phylogenetic analyses using the internal transcribed spacer regions (ITS) and the large subunit of nuclear ribosomal RNA gene (nLSU), four species in Exidia sensu lato, including Exidia saccharina and Tremellochaete atlantica, and two new species, Exidia subsaccharina and Tremellochaete australiensis, were identified. The four species are described and illustrated in detail. E. saccharina and T. atlantica, two known species from China are reported for the first time. E. subsaccharina and T. australiensis, two new species from France and Australia, respectively are also described. E. subsaccharina is characterized by its reddish brown to vinaceous brown basidiomata, slightly papillate hymenial surface, and narrowly allantoid basidiospores without oil drop measuring 12.5-17.5 × 4.2-5.5 μm. It differs from the similar species, E. saccharina, by distinctly larger basidiospores (12.5-17.5 × 4.2-5.5 vs. 10-14.2 × 3.2-4.5 μm). Tremellochaete australiensis is characterized by its white to grayish blue basidiomata, obviously and densely papillate hymenial surface, and allantoid basidiospores with oil drop measuring 13.8-16.2 × 4.8-6.5 μm. It also can be distinguished from the similar species, T. atlantica and T. japonica, by its distinctly larger basidiospores (13.5-17.8 × 4-5.2 vs. 10-11.8 × 4-4.8 μm in T. atlantica; 9.4-11.8 × 3.5-4.2 μm in T. japonica).

The genus Lactarius s. str. (Basidiomycota, Russulales) in Togo (West Africa): phylogeny and a new species described.

Project description:Lactarius s. str. represents a monophyletic group of about 40 species in tropical Africa, although the delimitation of the genus from Lactifluus is still in progress. Recent molecular phylogenetic and taxonomic revisions have led to numerous changes in names of tropical species formerly referred to Lactarius. To better circumscribe the genus Lactarius in Togo, we combined morphological data with sequence analyses and phylogeny inference of rDNA ITS sequences. Morphological and molecular data were generated from specimens sampled in various native woodlands and riverside forests; Lactarioid- and Russula sequences from public GenBank NCBI, and UNITE are included for phylogenetic analysis. The Maximum likelihood phylogeny tree inferred from aligned sequences supports the phylogenetic position of the studied samples from Togo within the subgenera Piperites, and Plinthogali. Lactarius s. str. includes about 13 species described from West Africa, of which eight were not previously known from Togo, including one new species: Lactarius subbaliophaeus identifiable by the presence of winged basidiospores, a pallisadic pileipellis with a uprapellis composed of cylindrical cells, inconspicuous pleurocystidia, and fusiform or tortuous, often tapering apex marginal cells. It can also be recognised by a transparent white latex that turns pinkish and then blackish, and a bluish reaction of the flesh context with FeSO4. These features mentioned do not match any of the morpho-anatomically most similar species, notably L. baliophaeus and L. griseogalus.

Three New Species of Russulaceae (Russulales, Basidiomycota) from Southern China.

Project description:The characterization of natural fungal diversity impacts our understanding of ecological and evolutionary processes and can lead to novel bioproduct discovery. Russula and Lactarius, both in the order Russulales, represent two large genera of ectomycorrhizal fungi that include edible as well as toxic varieties. Based on morphological and phylogenetic analyses, including nucleotide sequences of the internal transcribed spacer (ITS), the 28S large subunit of ribosomal RNA (LSU), the second largest subunit of RNA polymerase II (RPB2), the ribosomal mitochondrial small subunit (mtSSU), and the translation elongation factor 1-α (TEF1-α) gene sequences, we here describe and illustrate two new species of Russula and one new species of Lactarius from southern China. These three new species are: R. junzifengensis (R. subsect. Virescentinae), R. zonatus (R. subsect. Crassotunicatae), and L. jianyangensis (L. subsect. Zonarii).

Three new species of Aleurodiscus s.l. (Russulales, Basidiomycota) from southern China.

Project description:Three new species of Aleurodiscus s.l. with corticioid basidiomata are described and illustrated from southern China based on morphological evidence and phylogenetic analyses of ITS and nrLSU sequence data. Aleurodiscusbambusinus was collected from Jiangxi Province on bamboo and is distinct by having a compact texture, simple-septate generative hyphae, abundant acanthophyses, basidia with acanthophysoid appendages and smooth basidiospores. Aleurodiscusisabellinus was collected from Yunnan Province on both angiosperm wood and bamboo and is distinct by having soft basidiomata with yellow to yellowish-brown hymenophore, yellow acanthophyses, simple-septate generative hyphae and smooth basidiospores. Aleurodiscussubroseus was collected from Guangxi Autonomous Region and Guizhou Province on angiosperm wood and is distinct by having pinkish basidiomata when fresh, clamped generative hyphae, clavate acanthophyses and echinulate basidiospores. In the phylogenetic tree, A.bambusinus and A.isabellinus were nested within the A.cerussatus group, whilst A.subroseus was clustered with A.wakefieldiae. An identification key to 26 species of Aleurodiscus s.l. in China is provided.

Two new species of Scytinostroma (Russulales, Basidiomycota) in Southwest China.

Project description:Two new species of Scytinostroma viz. S. acystidiatum and S. macrospermum, are described from southwest China. Phylogeny based on ITS + nLSU dataset demonstrates that samples of the two species form two independent lineages and are different in morphology from the existing species of Scytinostroma. Scytinostroma acystidiatum is characterized by resupinate, coriaceous basidiomata with cream to pale yellow hymenophore, a dimitic hyphal structure with generative hyphae bearing simple septa, the absence of cystidia, and amyloid, broadly ellipsoid basidiospores measuring 4.7-7 × 3.5-4.7 μm. Scytinostroma macrospermum is characterized by resupinate, coriaceous basidiomata with cream to straw yellow hymenophore, a dimitic hyphal structure with generative hyphae bearing simple septa, numerous cystidia embedded or projecting from hymenium, and inamyloid, ellipsoid basidiospores measuring 9-11 × 4.5-5.5 μm. The differences between the new species and morphologically similar and phylogenetically related species are discussed.

Phylogenetic and microscopic studies in the genus Lactifluus (Basidiomycota, Russulales) in West Africa, including the description of four new species.

Project description:Despite the crucial ecological role of lactarioid taxa (Lactifluus, Lactarius) as common ectomycorrhiza formers in tropical African seasonal forests, their current diversity is not yet adequately assessed. During the last few years, numerous lactarioid specimens have been sampled in various ecosystems from Togo (West Africa). We generated 48 ITS sequences and aligned them against lactarioid taxa from other tropical African ecozones (Guineo-Congolean evergreen forests, Zambezian miombo). A Maximum Likelihood phylogenetic tree was inferred from a dataset of 109 sequences. The phylogenetic placement of the specimens, combined with morpho-anatomical data, supported the description of four new species from Togo within the monophyletic genus Lactifluus: within subgen. Lactifluus (L. flavellus), subgen. Russulopsis (L. longibasidius and L. pectinatus), and subgen. Edules (L. melleus). This demonstrates that the current species richness of the genus is considerably higher than hitherto estimated for African species and, in addition, a need to redefine the subgenera and sections within it.
