Abstract
Two new species from northern Thailand, Asterostroma bambusicola and A. vararioides, are described and illustrated. Asterostroma bambusicola is characterized by globose, echinulate, and amyloid basidiospores and growing on rotten bamboo. Asterostroma vararioides is distinguished by the presence of Vararia-like dichohyphae, subglobose, smooth, and amyloid basidiospores and growing on bark of living angiosperm trees. In the phylogenetic tree inferred from a combined dataset of ITS and nLSU sequence data of Peniophoraceae, A. bambusicola forms a distinct lineage in the sect. Asterostroma clade, whereas A. vararioides and A. laxum form the sect. Laevispora clade. Asterostroma andinum, reported from China for the first time, forms a distinct lineage sister to Gloiothele spp. and Scytinostroma portentosum group. Asterostroma muscicola is reported from Thailand and China for the first time. A key to the species of Asterostroma from Thailand and China is provided.
