In this paper, a combination of traditional morphological features and modern molecular phylogenetic analysis was used to identify and describe a gasteroid fungus collected from Guangdong. The studied specimens is Asperosporus subterraneus Karlsen-Ayala, Gazis & M.E. Sm., a member of the new genus Asperosporus Karlsen-Ayala, Gazis & M.E. Sm. of Agaricaceae which newly reported from Florida, USA, and firstly reported from China. A. subterraneus was mainly characterized by its irregular spherical basidiomata, white to grayish white at first, then becoming brownish when mature, rapidly stain pinkish-red when cut or bruised, earthy smell, Basidiospores, 14-18 μm×11-16 μm, broadly elliptical to subglobose and thick-walled basidiospores ornamented with larger pyramidal to irregular warts, turn to orange brown in 5% KOH solution and dark brown when added to Melzer solution, and the spores were often attached with sterigma remnants. Specimens were deposited in the Fungarium of Guangdong Institute of Microbiology (GDGM).
