There are several similar species of Clitocybe, and I wouldn't swear that the illustrated mushrooms are undoubtedly, definitively, decidedly Clitocybe eccentrica specimens--but what do you want me to be, a "mushroom expert?" I'm just an English teacher with a rather unfortunately named Web site. If "MushroomEquivocator.Com" weren't so hard to spell . . .
At any rate, Clitocybe eccentrica is characterized by its clustered growth on wood or woody debris (including wood chips) in eastern North America; the presence of numerous white rhizomorphs at the base of the stem; its small, whitish to pale brownish cap; its early-summer appearance (though it often continues to fruit until fall); and microscopic features (see below).
Clitocybe albirhiza is a larger, western species that also has numerous rhizomorphs. It is usually collected in early spring under Engelmann Spruce at high elevations.
Ecology: Saprobic; growing gregariously or, more often, in clusters on wood (primarily the wood of hardwoods) or woody debris; late May through fall; widely distributed east of the Rocky Mountains.
Cap: 1-6 cm; convex, becoming flat or shallowly vase-shaped; dry; smooth; whitish to pale brownish; usually changing color markedly as it dries out; the margin frequently inrolled.
Gills: Running down the stem; fairly crowded; white or buff.
Stem: 3-5 cm long; up to 7 mm thick; often somewhat off-center (hence the species name); more or less equal; dry; smooth or finely hairy above, densely hairy ("strigose") at the extreme base; with white rhizomorphs attached.
Flesh: Thin; watery or pale.
Odor and Taste: Taste not distinctive or bitter; odor not distinctive or somewhat fragrant.
Spore Print: White to creamy.
Chemical Reactions: KOH on cap surface yellowish to yellow.
Microscopic Details: Spores 4.5-6 x 2.5-3.5 µ; elliptical; smooth; inamyloid. Clamp connections present.
