Takah. & Taneyama, The fungal flora in southwestern Japan, agarics and boletes 1: 45, 2016 Tylopilus callainus N. K. Zeng, Zhi Q. Liang & M.S. Su, Phytotaxa 343 (3): 271, 2018 Habitat. Solitary or gregarious on the ground in forests dominated by fagaceous trees including Lithocarpus spp. or Castanopsis kawakamii Hay. Distribution. Southeastern and southern China; Japan ( Terashima et al. 2016 ). Note. Tylopilus callainus N.K. Zeng et al. was described from the south of China ( Liang et al. 2018 ). This taxon was previously thought to be different from B. virescens Har. Takah. & Taneyama, a species described from Japan ( Terashima et al. 2016 ). After a careful re-evaluation of specimens, we now know that the two taxa are conspecific, and T. callainus is synonymized with B. virescens . Clarifying the taxonomic relationship between the two taxa also indicated that the B. virescens is a member of Tylopilus , and thus the new combination is proposed. Illustrations and a full description have been provided by Liang et al. (2018) . Specimens examined. CHINA.
