A sequestrate, truffle-like bolete species, Rossbeevera yunnanensis was described in 2012 based on a single specimen collected from Chuxiong Yi Autonomous Prefecture, Yunnan Province, China. I collected a second specimen from Hiroshima Prefecture, Japan. This is the first report of this truffle in Japan. The overall morphology of the Japanese specimen was identical to the holotype from China, and the internal transcribed spacer region and 28S of the nuclear ribosomal RNA gene between the Japanese and Chinese specimens showed 99.6% and 99.9% similarity, respectively. I discuss the possibility of long-distance spore dispersal of the species.
