    smooth mai'p,'in or ragged from the remains of the veil; substance cit licr compact, spongy, slightly fleshy, or membranaceous ; stem mostly lateral (orjvanting), when present, confluent and homogeneous with the hymenophorum; gills with a sinus or broadly decurrent tooth.—Hab. Most of the species grow on wood, a few only on the ground. Pleurotus corresponds with Claiidopus, Plate II. fig. 15, and GrepU dotus, Plate III. fig. 22. The species are large, handsome, and polymorphic, but some are small and resiipinate; they generally appear late in the year, and return, year after year, to the same habitat more frequently than terrestrial fungi: all are harmless and some edible. All become putrid when old, and never coriaceous or woody; in this they dift'er from Lenlinits, Paniis, Xerotiis, Trogia, Scliizophyllum, and Lemitc's. The species figured is Ar/ariciis (PleurotiisJ spongiosus, Fr. Spores •OOOi x 'OOOIS. The elongated shape is characteristic of many species of this subgenus. Subgenus 7. Collybia, Fr. Epicr. p. 81 (Plate I. fig. 7).— Pileus at first convex, with an involute margin; stem with a carti- laginous bark, of a ditferent substance from the hymenophorum, but confluent with it; gills aduate or sli^iitly attached (not decurrent).— Hab. Most of the species are epiphytal. Usually small and tough, lasting far into the winter; few only are known to be edible, as A. fnsipes. Bull, A. esculentus, Wulf., etc. Marasiiuus is closely allied io C'oUijhia. Colhjh'm corresponds with Leptoiiia, Plate II. fig. 16; Naucoria, Plate III. fig. 23 ; and Psilocybe, Plate IV. fig. 30. The species figured is A. (Colhjbia) fusipes. Bull. Spores -0002 X-00013 ; the small section shows young plant of A. (Collybia) macalalus, A. and S., to show involute margin of pileus. Subgenus 8. Mycena, Pr. Syst. Myc. vol. i. p. 140 (Plate I. fig. 8). —Pileus more or less membranaceous, generally striate, with the margin always straight, and at first pressed to the stem (never involute), expanded, carapanulate, and generally umbonate (not depressed as in Ompltalia); stem externally cartilaginous, tubular, not stuff^ed when young, confluent with the hymenophorum, but heterogeneous from it; gills never decurrent, though some species have a broad sinus near the stem.—Hab. Mostly epiphytal. Most of the species are small, beautiful, and inodorous, but some which have a strong alkaline odour are probably poisonous; none are known to be edible. They appear after rain in summer and autumn.
