Genus Cortinarius


This genus contains many species which are distinguished by the rusty yellow colour of their spores and by the webby character of the veil. It is of the utmost importance in identifying species of Cortinarius to know the colour of the gills of the young plant, as the gills of the old plants are almost uniform in colour, owing to their being dusted with the rusty yellow spores.

In addition, one should carefully note the colour of the young plant compared with the old; the surface, whether sticky or dry, smooth or hairy; the taste; and the markings left on the stem by the retreating veil.

All species have their gills attached to the stem, and some have them notched at the stem end. They may be looked for along the borders of woods and groves in hilly regions, during the latter part of the summer.
