Abstract

In this study, maximum likelihood and Bayesian inference phylogenetic trees were reconstructed for Pholiotina based on the phylogenetic framework of the genus established by Song and Bau and on a concatenated dataset of internal transcribed spacer (ITS), nuclear large subunit ribosomal DNA (28S), and translation elongation factor 1-alpha (tef1-α) sequences. The phylogenetic trees resolved Pholiotina into two monophyletic clades: one containing sect. Pholiotina and the other comprising sect. Vestitae together with sect. Intermediae. The infrageneric subdivision of the genus was also reviewed, and the taxonomic issues that remain to be addressed were proposed. By further integrating morphological evidence, three new species of Pholiotina were discovered from Jilin Province and the Xizang Autonomous Region: P. constrictibasidiata (characterized by basidia with a median constriction), P. raribasidiata (notable for its rare basidia and basidiospores), and P. jilinensis (distinguished by the absence of pileocystidia and germ pores, with its type locality in Jilin City). In addition, this study provides an identification key to the new species, together with morphological descriptions and line drawings.

Scale bars: 1 cm; T = holotype.

Pholiotina constrictibasidiata H.B. Song & J.L. Deng, sp. nov.

 

Etymology. The specific epithet “constrictibasidiata” refers to basidia that are subutriform to cylindrical, with a median constriction.

Diagnosis. The cheilocystidia of this species are predominantly utriform, making it easily confused with species of ser. Teneroides, however, most of its basidia are subutriform to cylindrical with a median constriction, which distinguishes it from other species in ser. Teneroides.

Pholiotina raribasidiata H.B. Song & J.L. Deng, sp. nov.

 

Etymology. The specific epithet “raribasidiata” refers to basidia being rare.

Diagnosis. The main distinguishing features of this species are basidiospores and basidia both rare (ratio of basidia to basidioles less than 1/20), pileus applanate when mature, cheilocystidia long-necked lageniform to nettle hair-shaped, some with swollen apex, sub-lecythiform. Based on these features, it can be distinguished from other species in sect. Vestitae.

Pholiotina jilinensis H.B. Song & J.L. Deng, sp. nov.

 

Etymology. The epithet “jilinensis” refers to the type locality, Jilin City, where the holotype of this species was collected.

Diagnosis. The basidiospores of this species are without germ pore, and the species was collected from Jilin Province. It is easily confused with P. serrata, which also comes from Jilin Province and lacks a germ pore, but P. serrata has non-lecythiform cheilocystidia, basidiospores 7–9 μm, and grows in moss layers in grasslands, thus can be distinguished from it.

Abstract

The genus Inocybe (Inocybaceae, Agaricales) is a globally diverse fungal lineage with significant ecological importance. In China, species belonging to Inocybe are widely distributed and exhibit exceptionally high diversity. However, the overall diversity of this genus in the country, particularly in the complex mountainous landscapes of southwestern China, remains severely underestimated. Here, based on morphological evidence and multi-locus (ITS, LSU, and rpb2) phylogenetic analyses, we describe three new species from the area, namely Inocybe subtropicocinnamomea, I. biformis, and I. fulvobasalis. Phylogenetically, I. subtropicocinnamomea is assigned to sect. Inocybe and occurs in subtropical broad-leaved or mixed forests. Inocybe biformis belongs to the smooth-spored temperate boreal clade (STBC) and is uniquely adapted to high-altitude subalpine coniferous habitats above 4000 m. Inocybe fulvobasalis is nested within the I. geophylla group and occurs in temperate broad-leaved and coniferous mixed forests. Detailed morphological descriptions, macroscopic photographs, line drawings, scanning electron micrographs of basidiospores, and taxonomic comparisons with allied taxa are provided for the novel species.

Abstract

Micropsalliota is a genus of small to relatively medium-sized saprotrophic mushrooms, with fibrillose-squamulose pileus surface, ellipsoid to amygdaliform or cymbiform basidiospores, usually with capitate cheilocystidia, and encrusted pileus hyphae. In this study, two new species, namely Micropsalliota latiumbonata and M. striata are described from Oman, based on morphology and multigene (ITS-28S-rpb2-tef1-α) phylogenetic analysis. Micropsalliota latiumbonata is characterized by a broadly umbonate pileus disc with fibrillose-squamulose surface, fibrils dark-brown and more or less recurved, cheilocystidia capitate with olivaceous capitulum, broadly fusiform to amygdaliform basidiospores measuring 6.0–7.0 × 4.0–4.5 µm, and occurring gregariously around termite mounds. Micropsalliota striata is another small-sized species with an acute papillate pileus disc with appressed fibrils, striate-appendiculate pileus margins, utriform cheilocystidia without a capitate apex, clavate to subglobose pileocystidia, and comparatively larger basidiospores (6.5–7.5 × 3.7–4.1 µm). Both the new species belong to Clade megaspora. A detailed description, photographs of basidiomata, illustrations of anatomical characteristics, a multigene phylogenetic tree, and morphological comparison with similar species are provided. With the description of these two species, the number of known species in Micropsalliota rises to 108.

Abstract

Southwest China is extremely rich in fungal resources, and a large number of new taxa have been discovered in recent years. In the present study, we examined 26 specimens of the genera Hydnum and Lentaria sensu lato, most of which were obtained in Yunnan Province. Through ITS-nrLSU-tef1 phylogenetic analysis, combined with morphological studies and geographic analyses, five new species were described, viz. Hydnum cremeum, H. flavoquamosum, H. roseoalbum, H. roseotangerinum, and L. subalpina. Furthermore, we also supplied new information on some known species, including host plants and new distribution records. We re-examined the holotype sequences of two known taxa, H. flabellatum and H. pallidomarginatum, treating H. flabellatum as a synonym of H. pallidomarginatum. Additionally, a key to Lentaria s.l. in China was provided.

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

As ectomycorrhizal fungi, the species in Hydnellum can form a mutualistic symbiosis with plant roots to promote the restoration of forest vegetation and the stability of forest ecosystems. Some Hydnellum fungi also have edible and medicinal values generating considerable economic benefits. In this study, a new species of Hydnellum collected from Hangzhou, eastern China, was described by utilizing morphological and phylogenetic analyses. Morphologically, Hydnellum hangzhouense was characterized by its light-colored and relatively thick pileus, simple septated generative hyphae, and subglobose to ellipsoid basidiospores. The phylogenetic analysis was conducted based on the combined sequences dataset (ITS + nLSU + nSSU + rpb2). The results indicated that H. hangzhouense formed an independent lineage which is closely related to H. crassipileatum and H. chocolatum. The detailed description, illustrations and phylogenetic tree for demonstrating the taxonomic positions of H. hangzhouense were provided.

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.

Abstract

Two new species, Phaeoclavulina aurea and P. fulva, were discovered and described from North China. Identification was based on morphological observations combined with phylogenetic analysis of nrITS–nrLSU sequences. Phaeoclavulina aurea is characterized by its pale yellow to golden yellow basidiomata, brownish black coloration with dark tips at maturity, and basidiospores bearing truncate spines. Phaeoclavulina fulva is distinguished by its dirty orange basidiomata, pale yellow stipe surface, and basidiospores ornamented with rounded warts. This study enriches the species diversity of Phaeoclavulina in North China.

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

A new edible Lentinus species, described herein as L. saisamorniae, was collected from local markets and natural habitats in northern Thailand between 2019 and 2021. This species is characterized by its small to medium-sized basidiomata, white to yellowish-white pileus, broadly ellipsoid to elongate-shaped basidiospores, dimitic hyphal system, and hyphal pegs. Nonetheless, its longer basidia and smaller basidiospores make it distinguishable from L. cladopus. A molecular phylogenetic analysis of the combined internal transcribed spacer (ITS) large subunit (nrLSU) of nuclear ribosomal DNA, and RNA polymerase II large subunit (rpb1) sequences supported the monophyly of L. saisamorniae as a distinct lineage within the genus Lentinus. Therefore, this new species was introduced based on both morphological characteristics and molecular phylogeny. A full description, illustrations, color photographs, and a phylogenetic tree to show the placement of L. saisamorniae are provided. Comparisons between the new species and morphologically similar and related species are discussed.

Abstract 

Xerocomus garhwalensis and Xerocomus rishikeshinus (Boletales, Basidiomycota) are described as species new to science from specimens collected in the Himalayas of northwestern India. Both were found in forests dominated by banj oak (Quercus leucotrichophora A. Camus), and they presumably form ectomycorrhizal associations with this tree species. Xerocomus has been variously defined morphologically, and a number of the species now assigned to the genus are sometimes considered to be members of the genus Boletus. The two new species were placed in Xerocomus largely on the basis of DNA sequence data, which are still rather limited for the assemblage of macrofungi present in northwestern India.

Abstract

Pseudosperma citrinostipes sp. nov. from southwestern China is described and illustrated based on morphological, ecological, and molecular data. The new species is characterized by a medium-sized slender habit, straw yellow to golden yellow pileus, crowded lamellae without olive tinges, an equal stipe with lemon yellow to golden fibrils, large ellipsoid to subphaseoliform basidiospores, subfusiform to lageniform cheilocystidia, and the presence of caulocystidia at the stipe apex. Phylogenetically, P. citrinostipes is placed in the P. rimosum complex and is sister to the rest of the taxa of the species complex.
