Brief Description:

Fruiting Body: Goblet shaped to cup shaped, with a stem; to about 1 cm wide and 4 cm high; upper surface bald, bright red; outer surface red, covered with dense white hairs; margin fringed with white hairs that aggregate into pointed bundles; stem 1-3 cm high, 2-5 mm thick, whitish to grayish, densely hairy; flesh thin and reddish.

Microscopic Features: Spores 20-35 × 14-17 µ; smooth; narrowly ellipsoid; when fresh sheathed with a thick hyaline perispore. Asci 8-spored; hyaline in KOH; inamyloid; cylindric. Paraphyses branched and networked, forming meshes and reticulate patterns; sometimes enclosing or encasing asci (and then sometimes creating the impression of asci with apical projections); septate; individual arms generally 1-3 µ wide; hyaline to, en masse, reddish in KOH. Hairs on excipular surface dissolving in KOH mounts to a central fragmented core of thin-walled, septate cells 4-5 µ wide—but in Melzer’s reagent clearly visible as long, thick-walled elements up to 1,000 µ long and 20 µ wide.
