Notes

The species is characterised by the small, thick, glabrous pilei and large truncate spores. Originally, the species was described from Australia, but currently presents a worldwide distribution. In South America, it has been recorded in Brazil. This is the first record of the species in Colombia.

Basidiome perennial, solitary or imbricate, sessile, attached by a narrow or broad lateral base. Pileus ungulate, glabrous, upper surface pale yellow, concentrically zonate (Fig. 2 E). Margin thick, round, slightly lobed. Pore surface cream. Pores round, 4-6 per mm. Tubes and context dull yellow. Hyphal structure trimitic, generative hyphae thin-walled, hyaline, with clamps, skeletal hyphae hyaline and thick-walled, binding hyphae hyaline and thick-walled. Basidiospores ellipsoid, truncate at the apex, hyaline to golden, thick-walled and dextrinoid 10.9-16.1 × 6.2-8.6 µm.
