Notes

The species is microscopically separated by the dendrohyphidia and larger basidiospores from similar species. It is distributed in Puerto Rico and Honduras (type locality), but certainly has a wider distribution in the Caribbean ( Ryvarden 2000). This is the first record of the species for Tolima.

Diagnosis

Basidiomes resupinate, brittle when dry (Fig. 3 D). Pore surface white when fresh and pale orange when dry. Pores angular to irregular, 2-4 per mm. Context very thin and white. Hyphal structure dimitic, generative hyphae hyaline, with clamps, skeletal hyphae predominant, thick-walled, hyaline. Dendrohyphidia present, in some cases with apical protuberances. Basidia with four sterigmata. Basidiospores cylindrical, smooth, thin-walled, negative in Melzer’s Reagent, 4.6-6.2 × 2.8-3.4 μm.
