This genus resembles Tricholoma, which belongs to the white-spored Agarics and Hebeloma, which is rosy-spored. The species grow on the ground, and are found chiefly after rain. The stem is fleshy or fibrous, soft, sometimes waxy. The cap has the margin incurved, the gills have a tooth (sinuate), and are adnexed to the stem. Some species smell of fresh meal.

Section 3. OCHROSPORÆ, BROWN OR OCHRACEOUS SPORES.
CORTINARIUS = a veil.

This genus has a veil resembling a cobweb. The gills generally become cinnamon-colored. They grow on the ground in woods, during late summer and autumn. Some of our most beautiful mushrooms belong to this group. The veil is not persistent, and soon disappears.

PHOLIOTA = a scale.

This genus mostly grows on trunks. The partial or secondary veil takes the form of a ring. The cap is often covered with scales.

INOCYBE = fibre and head.

This genus is distinguished by the silky fibrilose covering of the cap, which never has a distinct pellicle, and by the veil which is lasting and of like nature to the fibrils of the cap. All grow upon the ground.

HEBELOMA = youth and fringe.
