Clitocybe subconnexa and its close relatives (see the discussion below) are apparently widely distributed on our continent. The tendency to grow in tight clusters is an identifying feature, as is the white cap and stem, and the densely crowded gills, which are broadly attached to the stem or begin to run down it. The spore print is pinkish, and the spores are finely warty--features that lead some mycologists to place this species in a separate genus as "Lepista subconnexa."
Clitocybe fasciculata differs only in its "rancid farinaceous" odor and "disagreeable" taste (Bigelow, 1982), and Clitocybe densifolia differs only in spore size (4-4.5 x 2.5-3.5 µ). These slight differences in features seem unlikely to predict actual genetic difference, in my humble opinion.
Ecology: Saprobic; growing scattered or, more commonly, in clusters in leaf debris or conifer duff; appearing under hardwoods or conifers in a variety of diverse ecosystems; summer and fall--or over winter in warm climates; apparently widely distributed in North America.
Cap: 3-9 cm; convex with an inrolled margin, becoming planoconvex or flat, with an even margin; bald or with a satiny whitish sheen; dry; soft; white to buff, sometimes developing watery spots with age; the margin sometimes becoming lined and ridged with maturity.
Gills: Broadly attached to the stem or beginning to run down it; crowded; buff.
Stem: 2-8 cm long; up to 1.5 cm thick; more or less equal; bald or with a satiny whitish sheen; buff to grayish or watery brownish where handled; basal mycelium white, often copious.
Flesh: Whitish; not changing when sliced; fairly brittle.
Odor and Taste: Odor fragrant or not distinctive. Taste mild or slightly bitterish.
Chemical Reactions: KOH on cap surface negative.
Spore Print: Pinkish (sometimes nearly white).
Microscopic Details: Spores 4.5-6 x 3-3.5 µ; ellipsoid; finely warted; inamyloid. Cystidia absent. Pileipellis a cutis of elements 4-6 µ wide. Clamp connections present.
