=CLAU´DOPUS= Smith. _Claudus_—lame; _pous_—a foot. (Plate LXX.) [Illustration: CLAUDOPUS VARIABILIS. Natural size. ] =Pileus= eccentric, lateral or resupinate. =Spores= pinkish. The species of this genus were formerly distributed among the Pleuroti and Crepidoti, which they resemble in all respects except the color of the spores. The genus at first was made to include species with lilac-colored as well as pink spores, but Professor Fries limited it to species with pink spores. In this sense we have taken it. The spores in some species are even, in others rough or angulated. The stem is either entirely wanting or is very short and inconspicuous, a character indicated by the generic name. The pileus often rests upon its back and is attached by a point when young, but it becomes turned backward with age. The species are few and infrequent. All inhabit decaying wood.
