The North American Species of Crepidotus

34. Crepidotus quitensis Pat., Bull. Soc. Myc. France 9: 128. 1893.

Illustration: Fig. 87.

Pileus 1-6 mm broad, sessile, resupinate to reflexed, semiorbicular, reniform, to conchate, at first white, then brown, margin fuscous, floccose, puberulent, villose at the point of attachment. Context thin.

Lamellae narrow, close, radiating, fuscous-brown.

Spores 5-6(7), in diameter, globose or slightly subglobose, conspicuously punctate, usually appearing verruculose. Basidia 16-20 x 6-7 µ, 2-4 -spored. Pleurocystidia none; cheilocystidia 26-36 x 6-10 µ, irregularly clavate or ventricose, at times subcapitate or with a slight neck. Cuticle of repent hyphae, bearing a turf of colorless, thick-walled, branched hyphae, 3-7 µ broad. Clamp connections present.

Habit, Habitat, and Distribution: Ecuador, February.

Material Studied: ECUADOR: Patouillard, type (FH), collected by Lagerheim, near Quito, Feb., 1892.

Observations: The notes on microscopic characters above are drawn from a study of the type. We have found no report of it from North America, but since it might occur in southern Florida or in the West Indies, we include it here. Its larger spores and distant gills separate it from applanatus. Its gill-spacing and floccose-puberulent pileus distinguish it from malachius.
