Additions to the Entoloma (Agaricales, Entolomataceae) from China: Description of five species with one new to science

Summary

Researchers from China identified five species of Entoloma mushrooms in the Qilian Mountains, including one previously unknown species named E. griseopileum. This new mushroom species is distinguished by its gray color, textured cap, and ability to grow on wood. This discovery contributes to understanding the fungal diversity of this ecologically important mountain region in northwest China.

Background

Entoloma is one of the three most diverse genera in Agaricomycotina with over 1800 species worldwide. However, species diversity in China remains relatively poorly known compared to American and European regions. The Qilian Mountains represent a critical biodiversity corridor in northwest China connecting northern and southern regions.

Objective

To document and describe five Entoloma species collected from the Qilian Mountains in China, including morphological characterization and phylogenetic analysis. To formally describe one new species to science based on integrated morphological and molecular data.

Results

Five Entoloma species were identified and documented from the Qilian Mountains. One new species, E. griseopileum, was described in subgenus Leptonia, characterized by gray basidiomes, fibrillose pileus, and wood-decaying habit. Four known species were confirmed: E. glaucobasis, E. incanum, and E. verae in subgenus Cyanula, and E. fuligineocinereum in subgenus Nolanea.

Conclusion

This study adds significantly to knowledge of Entoloma diversity in China through the description of one new species and four additional records from the Qilian Mountains. The region demonstrates high macrofungal diversity and warrants continued exploration. All species are documented with descriptions, photographs, and molecular sequences for future reference.
