Abstract
Cystoderma comprises the species with heavily universal veil remnants on basidiomes, weakly to strongly amyloid basidiospores, evanescent floccose-scaly ring zone or persistent membranous ring, which were often encountered in forests and grassland. However, they were less studied than other mushroom groups mainly because of its unclearly phylogenetic position. In this study, we gathered 16 specimens from Southwest and Northwest China, where were the richest biodiversity areas in China, and produced their ITS and nrLSU sequences. The related morphological examinations and molecular phylogenetic analysis showed they belonged to eight species, of which four were new species, and named as Cystoderma lilaceum, C. pseudoamianthinum, C. rugosolateritium, C. subglobisporum, and of which two were new records from China, and they were C. granosum, C. subvinaceum. New species and new records were described in details and discussed with other species. This study not only showed the novel geographical distributions as well as high species diversity of Cystoderma in China, but also provided more research data for the further studies in mushrooms systematics.
