Camarophyllus borealis (Peck) Singer). Clemencon (1982) reported this North American species from central Europe. It resembles Hygrocybe virginea, but according to Clemencon’s description it differs in having a dry pileus.
Pileus hemispherical, about 1 cm. across, white, smooth, non-viscid; flesh thin, white, odourless; gills broad, thick, equal, arched, adnato-decurrent, white, stipe equal, smooth, dry, white, solid.
(from the “Twenty-sixth Report on the State Museum”):
“Pileus thin, convex or expanded, smooth, moist, white, sometimes striatulate;
lamellae arcuate-decurrent, distant, white; stem smooth, equal or tapering downwards, stuffed, white.
Plant 2’ (5 cm) high, pileus 8”-12" (2-3 cm) broad, stem 1" (2,5 mm) thick.
Ground in woods. Croghan and Copake. September and October.
The species is related to H. niveus but the pileus is not viscid."
