Cortinarius camphoratus

Cortinarius camphoratus (Fr.) Fr., Epicrisis Systematis Mycologici: 280 (1838)

Discussion:
Cortinarius camphoratus is a relatively common species in the Pacific-Northwest, recognized by it’s larger size, lilac to almost-white color, non-viscid cuticle and heavy lilac to white veil. The species has a distinctive and unpleasant odor described as rotten potatoes. If you are able to detect it, this is a strong diagnostic feature. Cortinarius putorius, Niskanen, Limat. and Ammirati, is a closely related species, sharing this odor. Cortinarius putorius is described as showing brighter violet tones when young and having a white rather than lilac universal veil when young.

Both Cortinarius camphoratus and putorius are in Cortinarius section Camphorati, characterized by a pallid to purple appearance, abundant veil and distinctive cheilocystidia – which are uncommon in Cortinarius.
