LEPIOTA
Amanita virosa for it. For this reason no one should eat L. naucina or any pure
white mushroom until he is absolutely certain he knows and can recognize
A. virosa.
As with most of the older genera of agarics, modern investigators tend to
spHt Lepiota into a number of smaller genera composed of groups of closely
related species. Two of these segregated genera have been recognized here,
Limacella including the viscid species formerly placed in Lepiota, and Cystoderma
including the species with granulose covering of the pilei and with the
lamellae attached to the stipe.
Key
1. Spore print green L. molybdites
1. Spore print white 2
2. Pileus glabrous, white; lamellae faintly pinkish in age L. naucina
2. Pileus more or less scaly 3
3. Annulus movable, fruiting bodies very large 4
3. Annulus not movable, fruiting bodies small to medium 5
4. Stipe glabrous, striate, turning reddish when wounded;
fruiting body about as broad or broader than tall L. brunnea
4. Stipe furfuraceous, not reddening when wounded; fruiting body
much taller than broad L. procera
5. Stipe glabrous 6
5. Stipe clothed with a floccose or filamentous sheath, sometimes scaly 7
6. Stipe equal, mostly less than Va, in. thick L. cristata
6. Stipe bulbous or ventricose, mostly Va in. or more thick;
whole fruiting body staining reddish when bruised or in age L. americana
7. Scales of pileus erect, wart-like; spores 7-9 ju long L. acutaesquamosa
7. Scales of pileus more or less appressed, patch-like;
spores 10-6 ^ long L. clypeolaria

PILEUS 2-5 in. broad, convex expanding to almost plane, obtuse or
broadly umbonate, bright tawny, tomentose, covered with erect, beaked or
squarrose, tawny brown scales which gradually fall off and leave tawny, fibril-
lose, scar-hke patches with paler flesh showing between, flesh not very thick,
soft, white. LAMELLAE free, very crowded, unforked, moderately broad, white,
pruinose on the edge, minutely saw-toothed, stipe 2-4 in. long, about )4 ii^-
thick, bulbous at base, equal or tapering slightly to the apex, dingy white,
covered with a dense cottony-fibrillose sheath, stuffed or hollow, annulus
white, with brownish scales on the lower surface, membranous, hanging loosely
around the stipe, sometimes disappearing, spores smooth, white, long-ellip-
soid, 7-9 X 2.5-3 /z.
