Assessment Notes

Taxonomic notes

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).
