Inocybe geophylla is a small white mushroom that is mycorrhizal with both conifers and hardwoods. The cap is campanulate to conical, dry and smooth. It initially has a cob-webby veil which serves to protect the immature whitish gills and developing spores. As the spores mature and are released, the gills turn brownish. The margin frequently splits as the cap opens. This mushroom has a spermatic odor that can be detected by squishing the flesh with your fingers. The stem, like the cap, is dry and smooth. Not edible.
