Cerioporus leptocephalus, commonly known as blackfoot polypore, is an inedible species of mushroom in the genus Cerioporus.

Taxonomy

Formerly placed in the genus Polyporus, the species was moved into Cerioporus in 2016.[1]

Description

The cap is convex when young, and soon flattens out into a mostly irregular shape. It is red-brown when young, yellowish grey when old and up to about 4 centimetres (1+12 in) in diameter.[2] The pores are white, turning slightly brown when bruised, and the spores are white. The stem is light yellowish brown, often with a black base.

Similar species

There are two other polypores with a black stem at the base, Polyporus badius with a shiny red-brown to purple-black cap which can grow up to 20 cm (8 in) across, and the dark brown, velvety Polyporus melanopus, which grows up to 10 cm across and can be found on dead wood.

Distribution and habitat

It can be found in North America, from January to April on the West Coast and May–July in the east. It usually grows on hardwood twigs and branches.[2]
