Cortinarius croceus

This Cortinarius belongs to a group of species with dry, fibrillose to silky fibrillose caps and brightly colored gills. Despite their beauty, they are not easily separated due to similar colors that often change with age. An example is Cortinarius croceus. The young caps are yellowish-brown to olivaceous brown but become reddish brown in age, while the gills are yellowish in youth, dark orange at maturity. For many years it has been confused with Cortinarius cinnamomeus. Both species have brownish caps at maturity, but C. cinnamomeus has orange gills when young, while those of C. croceus are yellowish.
