Abstract
A new record of Auricularia thailandica was archived and described from the Langbiang World Biosphere Reserve, Vietnam. The new record is foundto be a very likely to be in the same clade as in Thailand and China vouchers based on its gelatinous basidioma, pinkish-brown to reddish-brown pileus, and short, loose hairs on the abhymenium. These features, along with phylogenetic analyses using the combined ITS-nrLSU marker, strongly support this placement. For the cultivation, the suitable medium was YMB, and the optimal temperature and pH were 30oC and pH 5. Rubber sawdust supplemented with other nutrients was found to be suitable for forming fruiting bodies of A. thailandica with a biological efficiency of 16%.
