The Mycologic Flora of the Miami Valley, O. 63 
blackish. Stipe hollow, fragile, rather equal, floccose-scaly; the anuu- 
lus fugacious. Lamelle approximate, white. Spores .0055>.0035 mm. 
In woods. Pileus 1-2 in. broad, stipe about 2in. long. This is a 
variety of A. clypeolarius, Bull, according to Fries. 
e’. Pileus with whitish or alutaceous scales. 
17. A. crtstatus, A. & S.—Pileus slightly fleshy, campanulate, obtuse; 
cuticle at first contiguous, then seceding in subgranulose scales. Stipe 
hollow, slender, equal, silky-fibrillose ; the annulus seceding. Lam- 
elle free, at length remote. 7 
In woods among the old leaves, Pileus 1-2 in. broad, stipe 2-3 in. 
high. This plant is remarkable for its offensive odor. The-piléus is 
whitish, alutaceous or yellowish, it is fragile, and often split and ir- 
regular ; the stipe is curved or crooked and floccose. 
18. A. MIAMENSIS, n. sp.—White. Pileus somewhat fleshy, convex 
then explanate, even, scaly. Stipe hollow, glabrous, nearly equal; the 
‘annulus fragile. Lamelle approximate. Spores .006.003 mm. (See 
Plate III.) ; 
In woods upon the old leaves, Pileus 1-14 in. in diameter, stipe 
about 2 in. long. This plant differs from <A. ermineus; Fr., in its 
habitat, and in the pileus being scaly, and the stipe glabrous. 
B. Pileus dry, granulose. 
19. A. Naucinus, Fr.—Whitish. Pileus fleshy, soft ; cuticle, thin, 
glabrous, crumbling into granules; the center umbonate, even. Stipe 
rather hollow, fibrillose, tapering upward from the thickened base ; 
annulus thin, seceding. Lamelle free, approximate. 
On slopes and grassy grounds. Pileus 4-5 in. broad, stipe 3-4 in. 
high, and nearly an inch thick at the base. I have seen very few speci- 
mens of this plant, and have not had an opportunity to examine the 
spores ; they are said by Fries to be globose. A similar plant is 
culled A. nawcinoides by Prof. Peck ; in it the’ spores are subelliptic, 
and .0080.0056 mm. 
20. A. CARCHARIAS, Pers.—Pileus fleshy, convex, then plane, umbon- 
ate, granulose, flesh-color. Stipe stuffed, then hollow, somewhat bulbous, 
scaly, concolorous. Lamellz attached, pure white. 
In woods among the old leaves, not common. Pileus 1-2 in. broad, 
the stipe about 2 in. long. 
21. A. GRANOsUs, n. sp.—Pileus fleshy, convex, umbonate, furfurace-
