A new species of Papiliomyces (Clavicipiteae, Hypocreales) from China

Papiliomyces (Hypocreales, Sordariomycetes) was introduced to accommodate two species: Papiliomyces liangshanensis and Papiliomyces shibinensis. Later, Papiliomyces liangshanensis was renamed Ophiocordyceps liangshanensis. However, the Papiliomyces liangshanensis molecular data (Nepalese) used to establish the Papiliomyces genus was different from Ophiocordyceps liangshanensis (China) strains.This paper describes a new species, Papiliomyces longiclavatus, found in Yangchang District, Guiyang City, Guizhou Province, China. It is proposed, based on morphology and multilocus phylogeny (ITS, SSU, LSU, TEF1, RPB1 and RPB2). The new species is phylogenetically most closely related to Papiliomyces liangshanensis (Nepalese collections). However, Papiliomyces liangshanensis (Nepalese collections) requires morphological details and additional detection. The new species differs from other Papiliomyces species in having robust stroma with completely immersed perithecia, multi-septate ascospores, cylindrical secondary ascospores, two types of phialides and two types of conidia:longer α-conidia and longer β-conidia

Ophiocordyceps aphrophoridarum sp. nov., a new entomopathogenic species from Guizhou, China

Ophiocordyceps is the largest genus in the family Ophiocordicipitaceae, including many entomopathogenic species. In recent years, many species have been described in this genus, with a wide range of host insects. Entomopathogenic fungi include ecologically, economically and medicinally important species, but a large portion of their diversity remains to be discovered and described.In this study, a new species, Ophiocordyceps aphrophoridarum sp. nov, parasitising Aphrophoridae sp. (Hemiptera) is proposed from China, based on evidence from morphology and molecular phylogenetic analyses. This species is characterised by fibrous, pigmented stromata, cylindrical asci and filiform ascospores. Compared to its closest relative, O. tricentri, the new species has wider perithecia and longer asci. Molecular phylogenetic analyses of a multilocus dataset (consisting of SSU, ITS, LSU, TEF1, RPB1 and RPB2) confirm its placement in Ophiocordyceps. Ophiocordyceps aphrophoridarum is morphologically described and illustrated with colour photographs. Morphological comparisons with closely-related species are also presented in tabulated format

Identification of two new species and a new host record of Distoseptispora (Distoseptisporaceae, Distoseptisporales, Sordariomycetes) from terrestrial and freshwater habitats in Southern China

During our investigation of saprophytic fungi in Guizhou and Hainan provinces, China, three hyphomycetes were collected from terrestrial and freshwater habitats. Based on morphological characteristics and phylogenetic analyses of combined ITS, LSU, tef1-α, and rpb2 sequence data, two new species are introduced: Distoseptispora hainanensis and D. lanceolatispora. Additionally, one known species, D. tectonae, previously unreported from Edgeworthia chrysantha, is newly reported. Detailed descriptions, illustrations, and a phylogenetic tree to show the two new species and the new host record of Distoseptispora are provided. In addition, a checklist of Distoseptispora species with their locations, lifestyles, habitats, and hosts is provided

Exploring the microbial ecosystem of Berchemia polyphylla var. leioclada: a comprehensive analysis of endophytes and rhizospheric soil microorganisms

Endophytic and rhizospheric microorganisms associated with plants play a crucial role in plant health, pest and disease defense, and fruit yield by actively participating in the plant’s adaptation to its environment. In this study, high–throughput sequencing technology was employed to analyze the community structure and diversity of endophytic and rhizospheric soil microorganisms in Berchemia polyphylla var. leioclada. The results revealed significant differences in microbial diversity and community structure between the soil and plant compartments within the same geographic region. Microbial diversity and species composition varied among different geographic locations. The dominant bacteria in plants were Cyanobacteria and Proteobacteria, with dominant genera including Methylobacterium-Methylorubrum, Escherichia-Shigella and Sphingomonas. In contrast, the dominant bacteria in soil were Proteobacteria, Acidobacteriota, and Actinobacteriota, with dominant genera such as Sphingomonas, Conexibacter and Vicinamibacteraceae, with Sphingomonas was considered core groups present in all plant and soil samples. As for fungi, the dominant phyla in both plants and soil were Ascomycota, Basidiomycota, and Mortierellomycota, with different dominant genera between the two compartments, including Fusarium, Septoria, and Mortierella, totaling 59 genera. Linear discriminant analysis at the genus level identified 102 bacterial and 54 fungal indicator taxa associated with plants and soil. Co-occurrence network analysis indicated close interactions among soil bacterial microorganisms. Functional prediction of the top 10 microbial genes revealed three bacterial metabolic pathways shared between soil and plants, while the predominant fungal metabolic types were similar between the two compartments but with varying abundances. This study elucidates the diversity and interplay of endophytic and rhizospheric microorganisms in Berchemia polyphylla var. leioclada across diverse geographical regions, providing insights crucial for the plant’s conservation and development
