Boletus umbrinipileus is an edible basidiomycete mushroom, of the genus Boletus in the family Boletaceae. Morphologically similar to Boletus phaeocephalus and belonging to the porcini group (Boletus sect. Boletus), it was first described in 2015, and is known to be found only in China, Yunnan.[2]

The pores are stuffed with white when young, becoming pallid yellow with slightly olivaceous tinge, unchanged when bruised.

Stipe

From 8.5 to 10 cm long; 0.8–1.5 cm thick; subcylindrical shape; upper two-thirds colored brownish to grayish brown and covered with whitish reticulations which become more enlongated downward; lower one-third colored dirty white to white and not reticulated.
