Remarks (internal):This species is previously known from Argentina (Rajchenberg, 2002) and reported from Venezuela by Hjortstam, Ryvarden & Iturriaga (2005). It is worth noticing that Rick (1933) described Odontia rosea from Brazil, which could be the same as S. fimbriatum (see Hjortstam & Ryvarden, 1982).
Specimen: Estado Aragua, Parque Nacional Henri Pittier, Rancho Grande Research Station, 21.II.2000, L. Ryvarden 42280.

Basidiome resupinate, adnate. Hymenophore odontioid, fairly tough, usually with a violaceous tint or especially when dried sometimes greyish, aculei somewhat conical, penicillate, about 0.2-0.3 mm long and 4-5 per mm, subiculum concolorous or slightly paler, 0.1-0.2 mm thick, margin more or less filamentous with several cm long threads. Hyphal system dimitic: generative hyphae thinwalled, 3.5-4 µm wide, with clamp-connections and sparse ramifications, in the aculeal trama intermingled with skeletals, skeletal hyphae thick-walled, (2.5-)3 µm wide, without clamp-connections, subhymenial hyphae short-celled, always with clamp-connections. Cystidia numerous, thin to moderately thick-walled, sometimes sinuous, usually strongly incrusted towards the obtuse apex, normally with the incrusted part 40-50 x 8-10 µm. Basidia subclavate, slightly sinuous, 18-20 x 4-4.5 µm, with four sterigmata and a basal clamp-connection. Spores ellipsoid, smooth, thin-walled, 3.25-4 x (2-)2.25-2.5 µm.
