Galera with ochraceous (ochraceous ferruginous) spores corresponds to Mycena among the white-spored agarics. The pileus is usually bell-shaped, and when young the margin fits straight against the stem. The stem is somewhat cartilaginous, but often very fragile. The genus does not contain many species. Peck gives a synopsis of five American species in the 23rd Report N. Y. State Mus., p. 93, et seq., and of twelve species in the 46th Report, p. 61, et seq. One of the common species is Galera tenera Schaeff. It occurs in grassy fields or in manured places. The plants are 5-8 cm. high, the cap 8-16 mm. broad, and the stem 2-3 mm. in thickness. The pileus is oval to bell-shaped, and tawny in color, thin, smooth, finely striate, becoming paler when dry. The gills are crowded, reddish-brown, adnexed and easily separating. The stem is smooth, colored like the pileus but a little paler, sometimes striate, and with mealy whitish particles above. Galera lateritia is a related species, somewhat larger, and growing on dung heaps and in fields and lawns. Galera ovalis Fr., is also a larger plant, somewhat shorter than the latter, and with a prominent ovate cap when young. Galera antipoda Lasch., similar in general appearance to G. tenera, has a rooting base by which it is easily known. Galera flava Pk., occurs among vegetable mold in woods. The pileus is membraneous, ovate or companulate, moist or somewhat watery, obtuse, plicate, striate on the margin, yellow. The plants are 5-8 cm. high, the caps 12-25 mm. broad, and the stem 2-3 mm. in thickness. The plant is recognized by the pale yellow color of the caps and the plicate striate character of the margin. The plicate striate character of the cap is singular among the species of this genus, and is shared by another species, G. coprinoides Pk.
