Notes

The size and shape of the spores, as well as the colour change from whitish to dark rusty brown are characteristic of this species. It is known from South America. This is the first record of the species for Tolima.

Diagnosis

Basidiomes gregarious, infundibuliform to flabelliform; upper surface glabrous, pale yellow when fresh, darker at the base, yellowish-brown when dry, with concentric and darker circles at the base (Fig. 3 C and 7). Stipe short and hirsute. Hymenophoral surface smooth, ochraceous buff. Hyphal structure dimitic, generative hyphae hyaline, branched, with clamps; skeletal hyphae thick-walled, unbranched, 2.4-4.2 μm wide. Gloeocystidia abundant, undulant, thin-walled, with highly refractive contents, 34-78 × 6.8-8.6 µm. Pileocystidia subcylindrical, with strongly thickened walls, up to 64 μm long and 110 μm wide. Basidiospores broadly ellipsoid, hyaline, thin-walled, negative in Melzer’s Reagent, 3.5-4.6 × 3-4 μm.
