Crepidotus applanatus var. applanatus (Pers.) P. Kumm.

Picture of <i>Crepidotus applanatus var. applanatus</i>

Gregarious (3) among mosses on rotting log of Acer sp.? (wood sample included with specimen), Spednic Lake Protected Natural Area, 600 m NW of Bolton Lake, York Co., New Brunswick (17-08-17/02).

Basidiospores brown in spore print, spherical or nearly so, finely verruculose, 3.8-4.9 X 3.6-4.7 μm, D/d = 1.00-1.08 (average[31]: 4.4 X 4.3 μm, D/d = 1.02). Cheilocystidia somewhat irregular in shape, clavate to ventricose-capitate, not branched, about 27-40 X 7-11 μm.

A nearly pure white species, including the lamellae, which may mislead a collector to believe it belongs to one of the Pleurotus look-alikes. The strong brown spore print will confirm its identity. The arguably distinct variety C. applanatus var. diversus differs in having the cheilocystidia branched or lobed at the apex.
