Notes

The septate basidia and the size of the spores make the species distinct. This is the first record of the species for Tolima.

Diagnosis

Basidiome annual, resupinate and effused, soft when fresh, up to 1 mm thick (Fig. 1 D). Margin narrow to absent, white to pale brownish. Pore surface reddish-white. Pores angular 4-6 per mm. Hyphal system dimitic; generative hyphae, thin-walled, hyaline, with clamps, 1.9-2 μm in diam., skeletal hyphae dominating in the trama, thick-walled, 2.8-4.3 μm in diam. Basidia longitudinally septate. Basidiospores allantoid to cylindrical, hyaline, smooth, thin-walled, negative in Melzer’s Reagent, 4.8-5.8 × 2-2.9 μm.
