Tropicoporus stratificans G.Coelho & Yurchenko

Phytotaxa 245 (2): 147 (2016).

SPECIMEN EXAMINED. — Brazil, Alagoas State, Quebrangulo City, REBIO de PedraTalhada, on dead wood, 09°14’57.7”S, 36°25’39.7”W, 724 m, 14.VII.2019, V. R. T. Oliveira, (URM[URM94063]).

REMARKS

The specimens from Northeast (URM94063) ( Fig. 9 E-H) and Southern Brazil (SMDB14731 and SMDB14732) clustered with good support in the ITS tree (PP = 1, bootstrap = 93%). Our collection differs from the original description and holotype illustrations mostly by the somewhat lanceolate setae (however dimensions are identical), and the presence of abundant rhomboid crystals immersed in the tube trama. The stratified basidioma, tendency to form elongated pores in vertical parts and the velutinate margin make T. stratificans a distinct species in the region.
