Summary: Features include an orange brown cap, decurrent whitish gills, a stem colored about as the cap, strong farinaceous odor and taste, habitat in the open, and a white or cream spore deposit. The description is derived from Bigelow(5) except where noted.
Gills: short-decurrent, close, moderately broad (0.4-0.7cm), rather brittle when old, forked at times; whitish to cream; often interveined, (Bigelow), decurrent, close; light pink, (Schalkwijk-Barendsen), +/- decurrent, 29-39 reaching stem, 5-7 subgills between each pair of neighboring gills, broad; whitish when young, later yellow-ocher; edges entire, (Breitenbach)
Stem: (1.5)3-5cm x 0.3-0.7(0.9)cm at top, eccentric [off-center] at times, equal or the top enlarged, stuffed, becoming hollow in large specimens; colored as cap or brown to orange brown; appressed-fibrillose striate or +/- bald-appearing, "base with white tomentum and white rhizomorphs at times", (Bigelow), 3.0-5.0(6.0) x 0.5-1.1(1.5)cm, equal, "stuffed, solid, corticate"; colored as cap; smooth, "longitudinally fibrillose, finely white-pruinose, apex somewhat floccose and grooved"; sometimes with rhizoids at base, (Breitenbach)
Veil: [presumably none]
Odor: strongly farinaceous (Bigelow), mealy or of cucumber (Schalkwijk-Barendsen), strongly farinaceous-rancid (Breitenbach)
Taste: strongly farinaceous (Bigelow), mild and farinaceous (Breitenbach)
Microscopic spores: spores (6)7-9(11) x 4-6 microns, elliptic to broadly elliptic or sometimes elliptic-oblong, smooth, inamyloid; basidia 4-spored or 2-spored, 25-40 x 6-8 microns; clamp connections present, (Bigelow), spores 6.7-8.9 x 4.2-6.2 microns, elliptic, smooth, iodine negative, colorless, with droplets; basidia 4-spored, 30-45 x 7-9 microns, narrowly clavate, with basal clamp connection; pleurocystidia and cheilocystidia not seen; septa with clamp connections
Spore deposit: white or cream (Bigelow), almost white (Breitenbach)

Habitat and Range
SIMILAR SPECIES
Clitocybe subsocialis has pinker colors, a more prominently squamulose cap, distant gills, a pallid stem, and most distinctively a different odor and taste which are disagreeable but not farinaceous, (Bigelow).
Habitat
single, scattered, sometimes gregarious, on sandy soil, frequently in the open along road shoulders and paths, occasionally in open woods, sometimes on recently burned areas, rarely on wood, "April to November but most frequently in June and early July", (Bigelow), "may be found at almost any time of year, often on bare soil", (Trudell), single to gregarious, "Along pathsides, on street embankments, under shrubbery, in coniferous forests on bare ground or among grasses or herbs, also in burned places", spring to summer, (Breitenbach), spring, summer, fall
