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).
