Notes

This species is recognised by the hydnoid or incised pore surface and the woolly tomentum under which there is a distinct black zone. In Colombia, this is the first record of the species for Tolima.

Diagnosis

Basidiome pileate, applanate, broadly attached. Pileus upper surface pale tan or dark ochraceous, tomentose to hirsute, with green shades in the basal tomentum because of algal growth (Fig. 3 J). Pore surface white to pale yellowish-brown. Pores slightly daedaloid, 1-2 per mm, dissepiments with an irregular hydnoid surface. Tubes concolorous with pore surface. Context dense, white to ochraceous, 2-7 mm thick, separated from the upper distinctly darker and looser upper tomentum by a distinct black zone. Hyphal structure trimitic, generative hyphae clamped, hyaline and thin-walled, skeletal hyphae abundant, hyaline and thick-walled, binding hyphae present. Basidiospores oblong ellipsoid, smooth, hyaline, negative in Melzer’s Reagent, 3.9-4.6 × 2.3-2.5 µm.
