Notes

The small vinaceous to purple basidiome are characteristic of this species, the allantoid to cylindrical spores separate it from species in Nigrofomes Murrill. The species present a Pantropical distribution. This is the first record of the species for Tolima.

Diagnosis

Basidiomes annual, effused-reflexed to pileate with contracted base. Pileus dimidiate to flabelliform, applanate, upper surface velutinate, vinaceous to purplish-brown, azonate (Fig. 3 H). Pore surface greyish-brown. Pores circular to irregular, 6-10 per mm (Fig. 3 G). Tubes concolorous with the pore surface or slightly greyish. Context dark brown, up to 3 mm thick. Hyphal structure dimitic; generative hyphae with clamps, thin-walled, skeletal hyphae thick-walled. Basidiospores allantoid to cylindrical, smooth, hyaline, negative in Melzer’s Reagent, 2.9-3.5 × 1.2-1.8 µm.
