Inocybe geophylla [Basidiomycetes > Agaricales > Cortinariaceae > Inocybe . . . ] by Michael Kuo There aren't a lot of white Inocybe species, and Inocybe geophylla is by far the most commonly collected species in the group. Distinguishing features also include the small size, the spermatic odor (crush a piece of the cap between your fingers--but read this if you're having trouble figuring out that olfactory description), and the smooth, elliptical spores. Inocybe geophylla var. lilacina has a purple cap. Description: Ecology: Mycorrhizal with hardwoods and conifers; growing alone, scattered, or gregariously; summer and fall (and winter in warm climates); widely distributed in North America. Cap: 1-4 cm; conical at first, becoming broadly bell-shaped or broadly convex; dry; silky or almost smooth; whitish; the margin often splitting when mature. Gills: Attached to the stem, sometimes by a notch; close; whitish, becoming grayish brown and eventually medium brown; covered at first by a cob-webby white cortina. Stem: 1-6 cm long; up to about .5 cm thick; more or less equal; dry; silky; whitish; fairly firm. Flesh: Whitish; insubstantial. Odor: Spermatic or sometimes not distinctive. Chemical Reactions: KOH on cap surface negative. Spore Print: Dull brown. Microscopic Features: Spores 8-10 x 4.5-6 µ; more or less elliptical; smooth. Cystidia up to 70 x 20 µ; fusoid or fusoid-ventricose, often with a flattened apex; abundant; thick-walled; apically encrusted. REFERENCES: (Persoon, 1801) Kummer, 1871.
