[In the nine subgenera following, from 20 to 28, viz. _Pholiota_, _Myxacium_, _Hebeloma_, _Flammula_, _Inocybe_, _Naucoria_, _Galera_, _Tapinia_, and _Crepidotus_, there are no esculent species.] Series 5. PRATELLA.[143] _Bot. Char._ _Veil_ not arachnoid; _gills_ changing colour, clouded, at length dissolving; _sporidia_ brown-purple. Subgenus 29. VOLVARIA. Esculent species: _none_. Subgenus 30. PSALIOTA.[144] _Bot. Char._ _Veil_ forming a partial ring-like investment, more or less persistent; _stalk_ robust, subequal, distinct from the pileus; _pileus_ fleshy, more or less campanulate when young, almost flat when fully expanded; sometimes sticky, sometimes scaly or else fibrillose, sometimes naked; _gills_ unequal, free, or connected with the stalk, broad and deepening in colour. In addition to the ring, some have a very fugacious _volva_ or _velum_, some both one and the other. Esculent species: _Ag. campestris_ and _Georgii_. [In the four next subgenera, from 31 to 34, _Hypholoma_, _Psilocybe_, _Psathyra_, and _Coprinarius_, there are no esculent species.] Subgenus 35. COPRINUS.[145] _Bot. Char._ _Gills_ free, unequal, thin, simple, changing colour, at length deliquescent. _Veil_ universal, floccose, fugacious; _stem_ fistulose, straight, elongated, brittle, subsquamulose, whitish; _pileus_ membranaceous, rarely subcarnose, when young ovato-conic, then campanulate, at length torn and revolute, deliquescent, distinct from the stem, clothed with the flocculose fragments of the veil. Fugacious funguses, growing in rich dungy places or on rotten wood. Esculent species: _Ag. comatus_ and _atramentarius_. Subgenus 36. GOMPHUS. No esculent species. GENUS 2. CANTHARELLUS.[146] _Bot. Char._ These are distinguished from Agarics, which at first sight they resemble, by having veins in place of gills; that is, by having the prolongations of the fibres of the pileus invested in an _undivided_, in place of a divided hymenium, as occurs in Agarics and in the genus _Boletus_. These veins are prominent, ramifying, seldom anastomosing; central, eccentric, or wanting; no investments; dust white. Esculent species: _C. cibarius_. [In the next three genera, _Merulius_, _Schizophyllum_, and _Dædalea_, there are no esculent species.] GENUS 6. POLYPORUS.[147] _Bot. Char._ _Hymenium_ concrete with the substance of the pileus, consisting of subrotund pores with thin simple dissepiments. Esculent species: _P. frondosus_. GENUS 7. BOLETUS.[148]
