This species is included in Amanita by Fries and Stevenson. Massee places it in Lepiota. In the dozen or more specimens I have found, there was no trace of a volva, even when very young. I tested it carefully and at one time ate three good-sized caps without experiencing any indications of poison. I have seen it during but one season and not then (at one time) in sufficient quantity to make a meal off it. Cooked it has a slight cheesy flavor which is pleasant. =L. illi´nita= Fr.—_illino_, to smear over. =Pileus= rather thin, soft, at first ovate, then campanulate or expanded, subumbonate, smooth, white, very viscid or glutinous, even or striate on the margin. =Gills= close, free, white. =Stem= equal or slightly tapering upward, stuffed or hollow, viscid, white. =Spores= broadly elliptical, 5×4µ broad. =Plant= 2–4 in. high. =Pileus= 1–2.5 in. broad. =Stem= 2–3 lines thick. Thin or open woods. Adirondack mountains. July to September. This is a smooth white species with the stem and pileus clothed with a clear viscid or glutinous veil. The margin of the pileus is often even, but the typical form of the species has it striate. The flesh is soft and white. The species may be distinguished from the viscid white species of Hygrophorus by the free, not adnate nor decurrent lamellæ. _Peck_, 35th Rep. N.Y. State Bot. Springton and Mt. Gretna, Pa., 1887–1897. _McIlvaine._ Not yet found by me in quantity. Several specimens eaten were of good flavor. =L. rugulo´sa= Pk. =Pileus= thin, submembranaceous, broadly convex or nearly plane, umbonate, rugulose, widely striate on the margin, whitish. =Lamellæ= thin, narrow, close, free, whitish. =Stem= short, equal, slightly silky, whitish, the annulus thin, persistent, white. =Spores= elliptic, 7.5µ long, 4µ broad. =Pileus= 12–20 mm. broad. =Stem= about 2.5 cm. long, 2 mm. thick. Moist grassy places under trees. Washington, D.C. July. _Mrs. E.M. Williams._ Perhaps in the fresh state the pileus is not as distinctly rugulose as when dry. _Peck_, Bull. Torrey Bot. Club, Vol. 27, January, 1900. [Illustration] =ARMILLA´RIA= Fr. _Armilla_, a ring. (Plate XVII.) [Illustration: ARMILLARIA MELLEA.] =Pileus= and =Stem= continuous. =Veil= partial, sometimes only indicated by the scales which clothe the stem terminating in the form of a ring. =Spores= white. On the ground or on stumps. In the young plant the veil extends from the stem to the pileus, sometimes forming scaly patches upon it; below the ring it is attached to the stem often in scales. But for the presence of the ring the species of this genus could be distributed in Tricholoma, Clitocybe and Collybia, with which they agree in all other characters. In Amanita and Lepiota, the other ringed genera of the white-spored series, the flesh of the stem and pileus is not continuous; and their stems are therefore easily separated. Amanita is also distinguished by its volva.
