Notes

It is a saprotrophic species growing on decaying wood. It is used to treat medical disorders and as a food ( Niño et al. 2017). Morphologically, this species differs from others of the genus by the presence and position of the medullary layer, as well as the size of the basidiospores. The species has been recorded in Antioquia, Amazonas, Boyacá, Caquetá, Cauca, Chocó, Cundinamarca, Norte de Santander, Quindío and Valle del Cauca. This is the first record of the species for Tolima.

Diagnosis

Basidiome pileate to substipitate, gelatinous, grey to reddish-brown, hairy surface, abhymenial hairs of 35-87 µm, with medullary layer closer to the abhymenium (Fig. 1 C). Hymenophore smooth to plicate. Generative hyphae with clamps, hymenium with crystals. Basidiospores cylindrical, hyaline, thin-walled and smooth, 13.9 × 5.3 µm.
