Description |
||
Viscid Violet Cort is a small gilled mushroom. It occurs in Europe, eastern Asia, North America, Central America, and northern South America. In the United States it occurs east of the Great Plains and on the West Coast. It is found from July to September, usually scattered or in groups, sometimes alone. It grows on the ground under hardwoods attached to the roots of a host tree. It has a mutually beneficial relationship (mycorrhizal) with the tiny rootlets of trees, absorbing sugars and amino acids while helping the tree absorb water. When it first appears, the cap is bell-shaped and dark lilac to purple. The upper surface is slimy and bald, with no hairs or scales. As it ages the cap expands, it develops yellowish spots, and the color fades. Mature caps are broadly convex or broadly bell-shaped, yellowish-tan or grayish-tan, and ¾″ to 2⅜″ (2 to 6 cm) in diameter. The margin is not lined. The gills are closely spaced and attached to the stalk. When young, the gills are protected with a partial veil that is cobwebby or silky in texture (cortina). They are pale purple to lilac at first, becoming grayish-cinnamon as the spores mature. Between the main gills there are one or two series of short gills that do not reach the stalk. The stalk is solid, slimy, 1½″ to 2¾″ (4 to 7 cm) long, and 3⁄16″to ⅝″ (5 to 15 mm) thick. It is club-shaped when young, enlarged near the bottom, becoming nearly equal from top to bottom at maturity. It is whitish to purplish or lilac, sometimes whitish toward the base. There is no ring but there is often a thin, fibrous, rust-colored zone near the top where the partial veil was attached to the stalk. The flesh is whitish to lilac. It does not change color when sliced. Eating it is not recommended. The spore print is rusty brown. |

Glossary
Cortina
On mushrooms: A thin, silky or cobwebby veil, attached to the cap and the stalk, that protects the developing gills.
Mycorrhizal
A symbiotic, usually beneficial relationship between a fungus and the tiny rootlets of a plant, usually a tree.
Partial veil
A protective covering over the gills or pores of a developing mushroom. At maturity it disappears, collapses into a ring around the stalk, or wears away into a cobwebby covering and ring zone.
