Abstract

A new species, Agrocybe himalayensis (Strophariaceae), from Uttarakhand Himalaya, India, is described based on macro- and micro-morphological characters and molecular phylogenetic analyses. This species is characterised by its pale-orange to yellow-brown pileus with distinct umbo, wavy cream margin, crowded pale-salmon to fleshy brown lamellae (often anastomosing), and ellipsoid basidiospores 8.7–11.4 × 6.6–7.8 μm. A phylogenetic tree, line drawings and photographs are provided, as is a table of morphological characters of the new and closely related species.

Abstract

Species of Gymnopus sect. Levipedes are challenging to delimitate due to the morphological similarity among different taxa. In this study, morphological characteristics, molecular phylogenetic data, and ecological traits were integrated to investigate the species diversity of this section of southwestern China. A total of 17 species were documented in the region, including three new species, namely G. sinobrevipes, G. flavoalbus, G. yunnanensis, and two species new to the studied area—G. bicolor and G. ocior. Detailed descriptions and illustrations of the three new species are presented, along with comparisons to closely related or morphologically similar species. The remaining species included five that were originally described from southwestern China, four that were first identified from Europe, two from the Republic of Korea, and one from North America. Six of these species, originally described outside of China, currently lack molecular evidence to support their distributions in southwestern China. Finally, 11 species with morphological and molecular evidence were recognized in southwestern China. A key to these species is also provided.

Abstract

Two new species of Leucoinocybe from southern China are described, illustrated, and compared with phenotypically similar and phylogenetically related species. Morphologically, L. danxiashanensis sp. nov. is characterized by its mycenoid basidiomata, light brown to brownish orange pileus with faintly yellow striations, decurrent lamellae, abundant lageniform to obclavate and thin-walled cystidia on pileus and stipe surface, and broadly ellipsoid to subamygdaliform basidiospores; and L. haizhuensis sp. nov. is characterized by its mycenoid basidiomata, brown, light brown to yellowish white pileus with pubescent, 2-spored basidia, ovoid, diverse cheilocystidia and elliptical to broadly elliptical basidiospores. Phylogenetic analyses based on sequences of the nuclear ribosomal large subunit (nrLSU) and the nuclear ribosomal internal transcribed spacer (nrITS) supported them as two distinct species of Leucoinocybe.

Abstract

In this article, we describe a new fungal species, Leucocoprinus roseus, collected in Canal View Park, District Mandi Bahauddin, Punjab, Pakistan. The species is proposed as new based on detailed morphological observations and molecular phylogenetic analysis using nuclear ribosomal DNA internal transcribed spacer (nrITS) sequences. In a phylogenetic reconstruction, L. roseus forms a distinct clade clearly separated from related taxa. It is characterized by small basidiomata, a plano-convex pileus with dark red center becoming pale reddish toward the margins, center covered with squarrose scales, broadly ellipsoid amygdaliform basidiospores and versiform cheilocystidia. A comprehensive description, illustrations, and results of the phylogenetic analysis are provided, along with a comparison with morphologically and genetically related species.

Abstract

An interesting species of lepiotaceous fungi, Leucoagaricus callainitinctus sp. nov., is described from Kerala State, India based on morphology and molecular phylogeny. This species is distinguished by basidiocarps that turn dark turquoise on bruising/handling or reacting with NH4OH. A phylogenetic study was conducted based on Maximum likelihood analysis of nrITS sequences. In the phylogram, the new species nested as a distinct lineage in a group, which consisted predominantly of members of section Piloselli of the genus Leucoagaricus. A comprehensive description, photographs of the basidiocarps and the microscopic structures, comparisons with phenetically similar and phylogenetically related species and a phylogram showing the placement of the new species are provided.

Abstract

This study investigates sequestrate boletes from southern Thailand and presents a morphologically distinctive specimen with a strong cantaloupe-like odor. Detailed morphological and molecular phylogenetic analyses, utilizing the internal transcribed spacer (ITS), large subunit ribosomal RNA (LSU) and RNA polymerase II second largest subunit (RPB2) genes were performed to determine its taxonomic position. Nonetheless, the new sequestrate bolete exhibited a distinctive morphological features, including a scaly peridium, a characteristic cantaloupe-like odor at maturity. Together with molecular evidence, these characteristics clearly distinguish it from other sequestrate boletoid (Chamonixia, Durianella, Octaviania, Rossbeevera, and Turmalinea). These findings support the recognition of a novel genus within the subfamily Leccinoideae. Therefore, we propose a new genus and new species, Sirindhornea siamensis, for this sequestrate bolete species.

Abstract

Four yeast strains representing three novel species were isolated from two sources in Thailand, one from the leaf surface of a tall-stilt mangrove (Rhizophora apiculata, strain DMKU-RG45) and three from the fruiting bodies of wild mushrooms (strains DMKU-TM03, DMKU-SM11, and DMKU-SM28) collected in Thailand. Sequence analysis of the D1/D2 domain of the large subunit (LSU) rRNA gene and the internal transcribed spacer (ITS) region revealed that these four strains differed by 0.87–8.68% and 2.07–13.55% in their nucleotide divergence from their closest described species in the sequences of the D1/D2 domain of the LSU rRNA gene and the ITS region, respectively. In phylogenetic analyses, the strain DMKU-RG45 belonged to the genus Cyberlindnera and was distinct from other recognized species in this genus, whereas the strains DMKU-TM03, DMKU-SM11, and DMKU-SM28 were members of the genus Blastobotrys. However, they were in two different positions, each of which was distinct from closely related species. Based on molecular analyses and phenotypic characteristics, the strain DMKU-RG45 is proposed as Cyberlindnera sirindhorniae f.a., sp. nov. (the holotype is TBRC 19863T; MycoBank No. is MB 858763). The other three strains (DMKU-TM03, DMKU-SM11, and DMKU-SM28) are proposed as two novel Blastobotrys species. Blastobotrys princeps f.a., sp. nov. is proposed to accommodate the strain DMKU-TM03 (the holotype is TBRC 19382T; MycoBank No. is MB 858764). Blastobotrys siamensis f.a., sp. nov. is proposed to accommodate both strains DMKU-SM11 and DMKU-SM28 (the holotype is TBRC 19380T; MycoBank No. is MB 858765).

Abstract

A novel cupulate basidiomycete fungus was discovered during a survey of mangrove-associated fungi in Chanthaburi and Phetchaburi Provinces, Thailand. This species, found exclusively on decaying Rhizophora mucronata hypocotyls in intertidal zones, forms minute fruiting bodies and shows close morphological and molecular resemblance to Calathella mangrovei Jones & Agerer, 1992. Phylogenetic analyses of ITS and LSU rDNA regions confirmed its placement within Calathella, as a distinct sister lineage to C. mangrovei. Therefore, these isolates represent a novel species, for which the name Calathella sirindhorniae sp. nov. is proposed.

Abstract

Laccaria is a large genus within the family Hydnangiaceae, and many potential species remain to be discovered in China. The present study describes three new species, L. carminostipes, L. mangshanensis and L. sinolateritia, and reports two new records, L. japonica and L. versiforma, which were originally discovered in Japan and Korea, respectively. These species were collected from subtropical mixed forests and identified based on morphological and phylogenetic evidence. Our phylogenetic analysis of the concatenated nucleotide sequences of ITS, LSU, TEF1 and RPB2 demonstrated that the three new species each formed a distinct clade, clearly separated from other known Laccaria species. A detailed description and illustrations of these species are also provided.

Abstract

Based on morphological and molecular evidence, 12 specimens have been identified as belonging to three previously unrecognized species of Clavaria, which are here described as C. divergens, C. orientalis, and C. tongdaoensis. Clavaria divergens is characterized by its branched, white basidiomata. Clavaria orientalis and C. tongdaoensis are very similar to C. zollingeri in the field. However, C. orientalis is distinguished by its more robust branches, while C. tongdaoensis differs by its varied or paler color of basidiomata. A concatenated sequence dataset (ITS-nrLSU-RPB2) was used for multi-locus phylogenetic analysis. The phylogenetic tree of Clavaria showed that the three branched species each formed a distinct lineage with strong support. A key to the known branched species of Clavaria in China is provided.

Abstract 

Phellodon is a globally distributed genus of stipitate hydnoid fungi recognised by a white spore print and an ectomycorrhizal life strategy. In Europe, many Phellodon species have declining populations and are used as indicators of forests with high conservation values. However, their use in this context and the correct assessment of their extinction risk, according to IUCN guidelines, are currently hampered by inconsistent name usage and unclear species delimitations, primarily within the species complexes of P. melaleucus, P. niger and P. tomentosus. We analysed 286 ITS sequences of Phellodon, of which 51 were also analysed in conjunction with the corresponding LSU regions. This work included 102 newly sequenced collections, primarily sourced from Sweden and the UK. Our phylogenetic results show that four species are new to science and hence we formally describe P. castaneoleucus within the P. melaleucus morphological complex, P. aquiloniniger and P. frondosoniger within the P. niger complex and P. dititomentosus as a sister species to P. tomentosus. The combination P. melilotinus is made to accommodate an additional, previously described, species that belongs in the P. niger complex. We designate lectotypes and epitypes for P. melaleucus, P. niger and P. tomentosus as well as an epitype for P. melilotinus. Phellodon ellisianus is recorded as new to Europe and the ecological amplitude of P. secretus and P. violaceus is revealed to be wider than previously believed. We provide a key to all 13 species currently known in Europe and assign them to three habitat-based assemblages based on data from the Nordic countries and the UK. We hope this will facilitate the assessment of such habitats for legal protection and other conservation-related actions.

Abstract

A new species of Pseudosperma is described based on collections recently made in Benin in West Africa. Pseudosperma brunneopilosum sp. nov. occurs in forests dominated by ectomycorrhizal Fabaceae Isoberlinia and Phyllanthaceae Uapaca trees. Phylogenetic analysis of combined ITS-LSU-RPB2-TEF1 gene regions shows that P. brunneopilosum is unrelated and distinct from several recently described species of Pseudosperma also from West Africa. Complete descriptions and illustrations, including photographs and line drawings are presented.

ABSTRACT

Two new Psilocybe species (Hymenogastraceae), P. ingeli and P. maluti, are described from southern Africa. Morphology and phylogeny were used to separate the two novel fungi from their closest relatives in the genus. Psilocybe ingeli was found fruiting on bovine manure–enriched grasslands in the Kwa-Zulu Natal Province of South Africa and differs from its closest relative P. keralensis and others in the internal transcribed spacer ITS1-5.8S-ITS2, partial 28S nuc rDNA, and translation elongation factor 1-alpha regions, distribution, and having larger basidiospores. Similarly, P. maluti was collected from the Free State Province of South Africa and observed in the Kingdom of Lesotho, growing on bovine manure. A secotioid pileus, geographic distribution, and differences in the same DNA regions distinguish P. maluti from its closest relative P. chuxiongensis. Furthermore, the spore dispersal and traditional, spiritualistic use of P. maluti are discussed here.
