Wood-inhabiting fungi can decompose wood materials and play a crucial role in the natural world by maintaining equilibrium of Earth's ecosystems. In present study, five new wood-inhabiting fungal species belonging to order Hymenochaetales, Hymenochaeteweishanensis, Lyomycesalbofarinaceus, Lyomycesalbomarginatus, Tubulicrinisalbobadius Xylodonmusicola, collected from southern China, are proposed based on combination morphological features molecular evidence. Hymenochaeteweishanensis is characterized coriaceous, tuberculate hymenial surface, monomitic hyphal system with simple-septate generative hyphae, ellipsoid narrow basidiospores (4.0-5.0 × 2.0-3.0 µm); Lyomycesalbofarinaceus pruinose clamped broadly (6.0-7.0 5.0-6.0 Lyomycesalbomarginatus cracked elliposoid (4.0-5.5 2.7-3.5 an arachnoid hyphae cylindrical allantoid (4.0-6.0 1.5-2.2 µm) Xylodonmusicola globe 3.5-5.0 µm). Sequences internal transcribed spacers (ITS) large subunit (nrLSU) nuclear ribosomal DNA (rDNA) markers studied samples were generated.

Catalogue of fungi in China 3. New taxa of macrofungi from southern Xizang, China

Mycology&#58 An International Journal on Fungal Biology, Год журнала: 2024, Номер 16(1), С. 91 - 123

Опубликована: Сен. 12, 2024

This is the third paper in series Catalogue of fungi China that aims to systematically and promptly publish Chinese fungal species. In this series, we focus on macrofungi from southern border area Xizang, a previously less concerned region. A total 15 new species six orders, 11 families, 12 genera Agaricomycetes, Basidiomycota are described. Both morphological phylogenetic analyses support identity these their taxonomic placements. addition, one combination Trechispora cryptomerioides proposed. We hope will draw more attention reporting diversity areas Xizang other special geographic regions besides aim itself.

Rostrupomyces, a new genus to accommodate Xerocomus sisongkhramensis, and a new Hemileccinum species (Xerocomoideae, Boletaceae) from Thailand

MycoKeys, Год журнала: 2024, Номер 103, С. 129 - 165

Опубликована: Март 28, 2024

A new genus, Rostrupomyces is established to accommodate Xerocomus sisongkhramensis based on multiple protein-coding genes ( atp 6, cox 3, tef 1, and rpb 2) analyses of a wide taxon sampling Boletaceae. In our phylogeny, the genus was sister Rubinosporus in subfamily Xerocomoideae, phylogenetically distant from , which highly supported as Phylloporus same Xerocomoideae. different other genera Boletaceae by following combination characters: rugulose subrugulose pileus surface, white pores when young becoming pale yellow age, subscabrous stipe surface scattered with granulose squamules, basal mycelium, unchanging color any parts, yellowish brown spore print, broadly ellipsoid ellipsoid, smooth basidiospores. addition, Hemileccinum inferius also newly described.

Three new wood-inhabiting fungi of Botryobasidium (Cantharellales, Basidiomycota) from subtropical forests of Southwestern China

MycoKeys, Год журнала: 2024, Номер 109, С. 337 - 354

Опубликована: Окт. 22, 2024

The basidiomycete genus Botryobasidium is a resupinate saprotrophic with global distribution range from coniferous to broad-leaved forest ecosystems. Though numerous species have been reported Eurasia and North America, few described China. In the current work, phylogenetic analyses of in China were conducted based on dataset internal transcribed spacer (ITS) regions large subunit (LSU) nuclear ribosomal RNA gene. Maximum likelihood Bayesian used reconstruct tree, three new species, namely acanthosporum , B. leptocystidiatum subovalibasidium subtropical forests Yunnan Province, Southwestern characterized by having yellowish white dark yellow basidiome, clavate tubular cystidia, subglobose globose basidiospores obtuse spines. fluffy arachnoid, greyish ivory generative hyphae clamped, subnavicular navicular basidiospores. While, subovoid basidia, suburniform basidiospores, thick-walled chlamydospores. These are illustrated, discriminating characters between their closely related discussed. A key known provided.

Cortinarius species are widely distributed in the world and constitute a diverse group of ectomycorrhizal fungi that associated with broad range plant hosts. The diversity this genus has been investigated China, but it remains poorly understood, especially subtropical region. In study, one new section, six novel species, combination, name, record reported from China based on morphological molecular evidences. lilacinicarpus, C. sinocalaisopus, sinosalor, vividus spp. nov., orientisalor nom. illibatus typical section Delibuti. macroflavicapus sp. nov. belongs to Macroflavicapi sect. subgenus Dermocybe. tianbaoyanensis dryadicola comb. belong Spilomei. Detailed descriptions, basidiocarps, microscopic photographs provided for these species. addition, leptospermorum Pauperae Dermocybe is proposed.

Four New or Newly Recorded Species from Freshwater Habitats in Jiangxi Province, China

Journal of Fungi, Год журнала: 2025, Номер 11(1), С. 79 - 79

Опубликована: Янв. 19, 2025

Freshwater fungi consist of a highly diverse group organisms in freshwater habitats worldwide. During survey fungal diversity across different regions Jiangxi Province, China, four were collected. To study their phylogenetic relationships, the internal transcribed spacer (ITS1-5.8S-ITS2), large subunit (28S, LSU), small (18S, SSU), and RNA polymerase II (RPB2) genes selected for analyses. Based on morphology coupled with analysis, these strains confirmed to belong Phaeoisaria, Pleurothecium, Pseudodactylaria. Among them, three as new species, namely, Pleurothecium lignicola (Pleurotheciaceae), Pseudodactylaria jiangxiensis (Pseudodactylariaceae), Ps. (Pseudodactylariaceae). One species was identified Phaeoisaria filiformis record this China. All compared other similar detailed descriptions, illustrations, data provided.

Wood-decaying fungi represent a vital group of higher that drive the cycling matter and energy in forest ecosystems, they have been focus thorough investigation. In this study, five new species, viz. Botryobasidiumdaweishanense, Inonotussubglobisporum, Kneiffiellabubalina, Xylodongranulanoides, X.granulans from China, are described illustrated based on morphological characteristics molecular phylogenetic analyses, which sequences ITS+nLSU genes were used for analyses by maximum likelihood Bayesian inference methods. The phylogeny revealed Botryobasidiumdaweishanense groups with three taxa, viz., B.intertextum, B.leptocystidiatum, B.subcoronatum. Inonotussubglobisporum is closely related to I.radiatus. Kneiffiellabubalina clustered sister K.subalutacea. Xylodongranulanoides close relationship X.bambusinus, X.fissuratus, X.subclavatus, X.montanus, X.wenshanensis. Additionally, together. characterized an araneose hymenial surface, fusiform, cyanophilous basidiospores (6.1-7.3 × 3.3-3.9 μm). perennial basidiomata lateral stipes, polygon pores measuring 4-6 per mm, subglobose, (3.6-4.3 2.8-3.5 cream cylindrical slightly allantoid (8.0-8.9 1.8-2.3 grandinioid surfaces, various cystidia, broadly ellipsoid, thick-walled (4.7-5.3 3.6-4.1 Xylodongranulans capitate clavate ellipsoid (3.8-4.2 2.9-3.3 Phylogenetic analysis internal transcribed spacer (ITS) nuclear large subunit RNA (nLSU) shows four species members Hymenochaetales, one belongs Cantharellales.
