When fresh and unfaded, Clitocybe odora is a gorgeous shade of bluish green and smells strongly of anise (like black licorice or ouzo), making it a fairly unmistakable mushroom. Whitish specimens are not uncommon, however, as a result of fading or lack of moisture (or sometimes simply because they're whitish)--and if these have lost the anise odor they can be rather difficult to separate from a host of similar Clitocybe species.
Ecology: Saprobic; growing scattered or gregariously on hardwood litter in eastern North America and on the debris of conifers (or hardwoods) from the Rocky Mountains westward; summer and fall (or winter in warmer climates); widely distributed in North America.
Cap: 2-11 cm; convex with an inrolled margin at first, becoming flat or shallowly vase-shaped; dry; finely hairy or smooth; blue-green to greenish, sometimes with a paler central area; fading quickly; in dry weather sometimes whitish; the margin often lined at maturity.
Gills: Attached to the stem or running down it; close or crowded; whitish to pinkish buff (or, in the Pacific Northwest's var. pacifica, green like the cap).
Flesh: Thin; whitish.
Odor and Taste: When fresh, strongly of anise.
Chemical Reactions: KOH on cap surface erasing green to pale orange.
