The recorded edible species are found in Volvaria, Clitopilus, and Pluteus. The Volvariae are characterized by the very large and perfect volva which wraps the base of the stem in loose folds, the ringless stem, and the pink, soft, liquescent gills, which are free and rounded behind. The cap is not warted; in some species it is viscid, and in _bombycinus_, recorded by several authors as edible, and by some as doubtful, it is covered with a silky down. In Clitopilus the odor of the edible species is more or less mealy. The cap is fleshy, and the margin at first involute. Two edible species which closely resemble each other--viz., Clitopilus _prunulus_, "Plum mushroom," and Clitopilus _orcella_, "Sweetbread mushroom,"--are highly recommended for their delicacy of flavor. In Leptonia most of the species are small, thin, and brittle, corresponding with Mycena in the white-spored series, and with Psathyra and Psathyrella in the dark-spored series. Eccilia corresponds with Omphalia. Claudopus corresponds with Pleurotus in its habit of growth and lateral stem, differing in the color of the spores. Annularia includes only a few small species having a ringed stem, no volva, and free pink gills. Cooke says of this subgenus that no British species are known. The recorded species of Pluteus have their habitat on tree stumps, sawdust, or upon fallen timber. One species, Pluteus _cervinus_, is recorded as edible, but not specially commended. Of Entoloma, Worthington Smith says, "It is allied to Tricholoma, though most of the species are thinner and often brittle. It agrees also in structure with Hebeloma and Hypholoma." None of the species are recorded as having value as esculents. The genus Bolbitius is described by Cooke as a small genus intermediate between Agaricus and Coprinus on the one side, and Coprinus and Cortinarius on the other. The species are small and ephemeral. Saccardo places Bolbitius in his division Melanosporae, although the spores are ochraceous. In the section Pratelli Psalliota and Hypholoma contain mushrooms which are of exceptionally fine flavor. In the first of these is found the common field mushroom Agaricus campester and its allies. The black-spored section Coprinarii contains two genera which include a few recorded edible species, viz., Coprinus and Gomphidius. The Psathyrellas correspond in size to the Mycenas in the white-spored series and to the Psathyras in the purple-spored section; the gills are free or adnate and turn black when mature. None of the species are edible. In Paneolus the plants are somewhat viscid when moist, the gills are described as "clouded, never becoming purple or brown." They are usually found on manure heaps near cities. None are edible. Saccardo in his Sylloge combines the Pratellae and Coprinarii, making of them one section which he calls _Melanosporeae_.
