Polyporus leprieurii has basidiomata annual to biannual, centrally to laterally stipitate; pileus flabelliform to spathulate, often partly imbricate, 2-5 cm wide, up to 2 mm thick, coriaceous when fresh, hard when dry, upper surface pale tan when fresh, isabelline to tobacco brown when dry, glabrous, azonate to radially striate; pore surface tan to typically greyish brown, pores round to angular, small, 5-8 per mm, strongly delimited towards the stipe; context ochraceous to beige, less than 1 mm thick; stipe up to 2 cm long and 2-3 mm wide, round, black and glabrous, usually elongating to form rhizomorphs up to 12 cm long (Núñez et al. 1995). Polyporus guianensis is a similar species, but differs by having larger pores and smaller basidiospores [8-12 x 2.5-4 µm in P. guianensis and 4.5-7 x 2-2.5(3) µm in P. leprieurii (Gomes-Silva et al. 2012).

The species occurs in several countries, with most records in Brazil.

There are about 898 reports of this species in GIBF, most of them in Brazil.

This species occurs in three Brazilian biomes: Amazon, Caatinga, Cerrado and Atlantic Forest.

It presents no evident threat, being very common at least in Brazil. However, it is found in the Atlantic Forest, a hotspot, in the Amazonia (currently being deforested at the highest rates in the last decades) and Cerrado (also a hotspot).

Some records are in unprotected areas.

Other countries should be better surveyed for a better understanding of distribution of the species.
