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

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

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

During field surveys conducted in various regions of Thailand, several fungal specimens parasitising flies were discovered. These fungi exhibited morphological characteristics consistent with the broad concept of Ophiocordyceps dipterigena, including yellow to orange-brown cylindrical stromata bearing fertile ascomata at the tip. Multi-locus phylogenetic analyses based on ITS, LSU, TEF1, and RPB2 sequences revealed that these specimens belong to a well-supported monophyletic clade, referred to as the 'O. dipterigena' complex, which forms a distinct subclade within the hymenostilboid clade. This complex comprises four newly described species with clearly defined host associations: O. floriformis, found on robber flies (Asilidae), particularly on Clephydroneura sp.; O. muscae, isolated from the housefly (Musca domestica); O. tabani, parasitising horse flies (Tabanus sp.); and O. thilosuensis, infecting fruit flies (Anastrepha obliqua) and soldier flies (Sarginae). Additionally, several strains clustered with the previously described O. philippinensis, which was also collected from Clephydroneura sp. This marks the first record of O. philippinensis in Thailand.

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.

Background: As a genus within the Clavicipitaceae, Metarhizium exhibits rich morphological and ecological diversity, with a wide distribution and a variety of hosts. Currently, sixty-eight species of Metarhizium have been described.

New information: A new species of Metarhizium, M. puerense (Hong Yu bis), was described in Pu'er City, Yunnan Province, south-western China. Based on morphological characteristics and multilocus phylogenetic analyses, Metarhizium puerense was confirmed to be phylogenetically related to M. album, but was clearly separated and formed a distinct branch. In contrast, the host of Metarhizium album was plants and leafhoppers and that lepidopteran larvae were the host of M. puerense. The diagnostic features of M. puerense were solitary to multiple stromata and smooth-walled, cylindrical with rounded apices conidia.

Abstract

The present study introduces a novel fungus, Cystoderma yongpingense, which was identified in the southwestern region of China. The new species is characterized by a pileus that ranges in color from light orange-red to orange-red; the pileus has a wrinkled surface and is accompanied by a persistent annulus that is membranous and floccose-scaly. Above the annulus, the color transitions from white to yellowish brown. This proposal is substantiated through analyses encompassing both morphological characteristics and phylogenetic relationships. The phylogenetic position of the newly discovered species has been further corroborated through comprehensive maximum likelihood and Bayesian sequence analyses of the ITS + nrLSU DNA regions. Additionally, the technical description of C. yongpingense is enhanced by detailed illustrations and comparative studies with species that are closely related.

Abstract

An updated description of the genus Atheniella, combining macro- and micromorphological characters that elaborate on the original generic characterisation, is presented. Atheniella is characterised by a brightly coloured pileus, all tissues inamyloid and pileipellis covered with simple to branched excrescences. Previously, nine Atheniella species were known globally, of which three species were accepted in China. Three newly-recognised species classified in the genus are here formally described from Yunnan Province: Atheniella flavida sp. nov., A. rutila sp. nov. and A. taoyao sp. nov. The new species are characterised by a yellow, orange, pink or red pileus, fusiform cheilocystidia and pleurocystidia, non-smooth pileipellis, stipitipellis smooth or with cylindrical ornamentation, caulocystidia fusiform or subglobose, if present and all tissues inamyloid. Morphological descriptions, photographs, line drawings and comparisons with closely-related taxa are presented for the new species. A phylogenetic analysis of sequence data for the rDNA internal transcribed spacer region and nuclear large ribosomal subunit (ITS + nLSU) supported that Atheniella is resolved as monophyletic and also supported the taxonomic recognition of the new species. A key to the 12 species of Atheniella is also provided.

Abstract

The genus Favolaschia within the family Mycenaceae is characterised by the gelatinous basidiomata with poroid hymenophore and most species inhabit monocotyledonous plants. In this study, many samples covering a wide geographic range in China were examined morphologically and phylogenetically using concatenated ITS1-5.8S-ITS2-nLSU sequence data. Three new species clustering in Favolaschia sect. Anechinus, namely Favolaschia imbricata, F. miscanthi and F. sinarundinariae, are described. Favolaschia imbricata is characterised by imbricate basidiomata with pale grey to greyish colour when fresh and broadly ellipsoid basidiospores measuring 7–9 × 5–6.8 µm; F. miscanthi is characterised by satin white basidiomata when fresh, broadly ellipsoid basidiospores measuring 7.5–10 × 5.5–7 µm and inhabit rotten Miscanthus; F. sinarundinariae is characterised by greyish-white basidiomata when fresh, dark grey near the base upon drying, broadly ellipsoid to subglobose basidiospores measuring 7–9 × 5–7 µm and inhabit dead Sinarundinaria. The differences amongst the new species and their morphologically similar and phylogenetically related species are discussed. In addition, an updated key to 19 species of Favolaschia found in China is provided.

Abstract

Molecular phylogenetic and chemical analyses, and morphological characterization of collections of North American Paraisaria specimens support the description of two new species and two new combinations for known species. P. cascadensis sp. nov. is a pathogen of Cyphoderris (Orthoptera) from the Pacific Northwest USA and P. pseudoheteropoda sp. nov. is a pathogen of cicadae (Hemiptera) from the Southeast USA. New combinations are made for Ophiocordyceps insignis and O. monticola based on morphological, ecological, and chemical study. A new cyclopeptide family proved indispensable in providing chemotaxonomic markers for resolving species in degraded herbarium specimens for which DNA sequencing is intractable. This approach enabled the critical linkage of a 142-year-old type specimen to a phylogenetic clade. The diversity of Paraisaria in North America and the utility of chemotaxonomy for the genus are discussed.
