Subgenus 8. CLYTOCYBE.[126] _Bot. Char._ _Veil_ none; _pileus_ at first convex, at length infundibuliform; _gills_ unequal. The characteristics of this subgenus are rather negative than positive; many of the contained species vary considerably amongst themselves, but the subdivisions founded on such variations are all well marked. Subdivision _Dasyphylli_.[127] _Gills_ in close juxtaposition, decurrent or acutely adnate. Esculent species: _Ag. nebularis_. Subdivision _Camarophylli_.[128] _Pileus_ subcompact, dry; _gills_ very distant, vaulted, decurrent. Esculent species: _Ag. virgineus_. Subdivision _Chondropodes_.[129] _Pileus_ tough, dry, _gills_ nearly free, close, white, external coat of stem subcartilaginous. Esculent species: _Ag. fusipes_. Subdivision _Scortei_. _Pileus_ subcoriaceous; _gills_ free, subdistant. Esculent species: _Ag. oreades_. Subgenus 9. COLLYBIA.[130] Esculent species: _none_. Subgenus 10. MYCENA.[131] Esculent species: _none_. Subgenus 11. OMPHALIA.[132] Esculent species: _none_. Subgenus 12. PLEUROPUS.[133] _Bot. Char._ _Pileus_ unequal, eccentric or lateral; _stem_, when present, solid and firm; _gills_ unequal, juiceless, unchangeable, acute behind, growing on trees or wood; for the most part innocuous, but two only generally eaten. Esculent species: _Ag. ostreatus_, in the subdivision _Concharia_; and _Ag. ulmarius_, in the subdivision _Ægeritaria_. Series 2. HYPORHODEUS.[134] _Sporules_ pale rose-colour. Subgenus 13. CLITOPILUS.[135] _Bot. Char._ _Veil_ none; _stem_ tolerably firm, subequal, distinct from the pileus; _pileus_ fleshy, campanulate or convex, at length somewhat plane, dry, regular; _gills_ unequal, changing colour as the fungus matures its seed, fixed, or free. Esculent species: _Ag. orcella_. Subgenus 14. LEPTONIA.[136] Esculent species: _none_. Subgenus 15. NOLANEA.[137] Esculent species: _none_. Subgenus 16. ECCILIA.[138] Esculent species: _none_. Series 3. CORTINARIA.[139] _Sporules_ reddish-ochre; _veil_ arachnoid. Subgenus 17. TELAMONIA.[140] Esculent species: _none_. Subgenus 18. INOLOMA.[141] _Bot. Char._ _Veil_ fugacious, marginal, consisting of free arachnoid threads; _stem_ solid, bulbous, fibrillose, more or less diffused into the pileus, fleshy; _pileus_ fleshy, convex when young, then expanded, fibrillose, or viscid, regular, juicy; _gills_ emarginato-adnexed, broad, changing colour; colour of the gills or pileus violet. Large autumnal funguses growing on the ground. Esculent species: _Ag. violaceus_. Subgenus 19. DERMOCYBE.[142] _Bot. Char._ _Veil_ dry, arachnoid, very fugacious; _stem_ not truly bulbous, fibrillose, stuffed when young; _pileus_ clothed with fibrillæ, rarely with gluten; _gills_ rather unequal, broad, close. Esculent species: _Ag. castaneus_. Series 4. DERMINUS.
