(From the pileus, which is frequently small and regular in form 

 like a small coin ; Gr. kollubos)

 floccose, or pruinose covering. Hymenophore confluent with, but

thin, margin at first involute. Stem central, wholly cartilaginous,, 

 or with a cartilaginous bark and stuffed with a pith ; often rooting, 

 simple. Gills membranous, soft, free or adnexed. Spores smooth.

Often small, frequently somewhat tough, maturing more slowly 

 and lasting longer than other Agarics. The species grow on stumps, 



branches and leaves, sometimes on 



other fungi 



or on the ground. 



Must be carefully distinguished from members of Afarasmius, where 

 the species are less fleshy, less putrescent, more leathery, and revive 

 with moisture after becoming dry. Species 225 — 286 



A. Gills white or brightly coloured, not ashy. Flesh white.
