Fungicolous on mushrooms: One novel species and six host records from southwest China and northern Thailand.

species are a group of common soil-borne fungi, known to cause infections on humans and animals, interfere in food production, and act as useful agents in biotechnological applications. This study reports one new species, , which was found to be fungicolous on an sp. from southwest China. Further, on sp., on sp. and sp., on sp., on sp., and on sp. are reported as new host records. and have been collected from Yunnan Province in China, whereas , and have been collected from Chiang Mai and Chiang Rai Provinces in Thailand. All the taxa reported herein were identified based on both morphology and phylogenetic analyses of a combined nuc rDNA internal transcribed spacer region ITS1-5.8S-ITS2 (ITS) and partial nuc 28S rDNA (28S) sequence matrix. Comprehensive descriptions, illustrations, and a phylogenetic tree are provided for all the taxa reported in the study to show the placements of taxa, and the new taxon is compared with its sister taxa.
