Habitat.

Solitary or gregarious on the ground in forests dominated by fagaceous trees including Lithocarpus spp.

Distribution.

Southern and southwestern China; Japan ( Hongo 1968).

Note.

Boletus obscureumbrinus Hongo was originally described from Japan ( Hongo 1968) and later reported from Guangdong Province of southern China and Yunnan Province of southwestern China ( Wu et al. 2016a). It was transferred to the genus Sutorius by Wu et al. (2016a); in the present study, we place the species in Neoboletus according to the evidence referred to above (Fig. 2). It is new to Hainan Province. The fruit body of this species is eaten by the Li people who live in the region (our own investigations).
