The majority of the members of this group grow in grassland, hill-pastures and meadows and distinct communities containing members of this family and of the _Hygrophoraceae_ can be recognised. It is not proposed to deal in detail with any individual members because they can be so easily confused with each other by the specialist let alone by the amateur. However, the genera as at present accepted are as follows:-- 1. ~Entoloma~ in its original sense contains agarics with fleshy caps, fibrous stems and sinuate or adnexed gills, e.g. _Ent. clypeatum_ (Fries) Kummer with grey to yellow-brown cap, found growing with members of the apple and rose-family in the summer and early autumn. This genus corresponds to _Calocybe_ in the white-spored agarics (p. 110). 2. ~Leptonia~ contains those agarics with rather thin caps whose margin is incurved, cartilaginous stems and adnate to adnexed, rarely decurrent, gills and whose cap flesh is indistinct from that of the stem, e.g. _Lept. serrulata_ (Fries) Kummer with dark blue to violet-blue cap and dark blue edge to the gills. This genus approaches the tough-shanks (_Collybia_) in the white-spored genera (p. 90). 3. ~Nolanea~ is characterised by agarics with delicate caps, whose flesh is distinct from that of the stem and whose edge is straight and pressed against the fragile stem when young, and the adnexed or adnate, rarely decurrent, gills, e.g. _N. staurospora_ (see p. 122). _N. cetrata_ (Fries) Kummer with yellow-brown to tan-coloured cap is found from spring to autumn in conifer woodland, especially plantations. The genus corresponds to _Mycena_ in the white-spored agaric genera (p. 68). 4. ~Eccilia~ is a small genus containing agarics with thin, membranous caps and distinctly decurrent gills, e.g. _E. sericeonitida_ P. D. Orton with convex, then umbilicate, silky greyish brown cap. This genus corresponds to _Omphalina_ in the white-spored agarics (p. 232). 5. ~Claudopus~ has three British representatives, all of which have a very small stem which may even be absent, e.g. _C. depluens_ (Fries) Gillet grows on soil and _C. parasiticus_ (Quélet) Ricken grows on old decaying fruit-bodies of woody fungi. This genus corresponds to _Pleurotellus_ in the white-spored genera and to _Crepidotus_ in the brown-spored genera (p. 77). [Illustration: Plate 28. Fleshy fungi: Spores pinkish and angular and borne on gills - Rhodophyllaceae] ~Cystoderma amianthinum~ (Fries) Fayod _Cap_: width 15-35 mm. _Stem_: width 4-8 mm; length 15-30 mm. _Description_: Cap: pale ochraceous yellow to sand-colour, convex then expanded, with central umbo and often radially wrinkled-reticulate, covered completely in powdery granules when fresh but these gradually disappear with age or on excessive handling.
