Cortinariaceae

Cortinariaceae

The Cortinariaceae is a large family of gilled mushrooms found worldwide. The family takes its name from its largest genus, the varied cortinars of the genus Cortinarius. Other notable genera include Hebeloma ,Gymnopilus, Galerina and Inocybe. Several genera, such as the skin-heads (Dermocybe) and Rozites appear to lie within Cortinarius as it now stands.

The deadly toxin orellanine has been found in at least 34 Cortinariaceae.

Taxonomic details

This is a family of mushrooms which has a hymenium on gills, a pileipellis which is a cutis, and spores which are brown in deposit. For most the genera in this family the spores will also be ornamented.

Differences in Genera

Cortinarius are mushrooms with warted spores, which are rusty-brown in deposit. Mushrooms in this genus have partial veil which is a cortina. These mushrooms will be terrestrial and mycorrhizal, and can range from small to large and fleshy.

Galerina are mushrooms with ornamented spores, where the ornamentation comes from a spore covering the breaks up on maturity. These mushrooms are small, and Mycena like, and are saprotrophic on mosses, grass and wood.

Gymnopilus are mushrooms with warted spores, which are orange-brown in deposit and are saprotrophic on wood. The caps of these will have a dry surface.

Hebeloma are mushrooms with dull brown colors, lightly warted (almost smooth) spores that are brown in deposit (not rusty-brown). These mushrooms will be terrestrial and mycorrhizal, and can range from small to large and fleshy just like Cortinarius, but are separated by always having cap with a gelatinous surface, the presense of cheilocystidia, and the absence of pleurocystidia.

Inocybe are mushrooms with a dry silky, radially fibrous cap surface, and spores with are nodulose or ellipsoid smooth and brown in deposit. These mushrooms will be terrestrial and mycorrhizal, and most tend to be small, with only a few that are large and fleshy.

Melonomphalia

Naucoria are mushrooms with warted spores, where the spores are lemon-shaped with pointed warts. These mushrooms tend to be small and non-descript little brown jobs.

Phaeocollybia are mushrooms that are umbonate with long rooting stipes, and spores that are brown in deposit. These are associated with the roots of trees (different trees for different species).
