The Mycologic Flora of the Miami Valley, O. 61 
Along the borders of woods and in pastures. Pileus 3-9 in. broad, 
stipe 5-9 in. high. The pileus is tough, dry and strongly umbonate, 
the cuticle being reddish brown, and broken so that the surface re- 
sembles brown shaggy leather. The stipe is brown-scaly, with some 
times peculiar snake-like spots. 
9. A. RHACopDES, Vitt.——Pileus fleshy, soft, globose, then explanate 
or depressed ; the cuticle thin, reticulate, broken up into persistent 
scales. Stipe hollow, even, bulbous ; the bulb ample, at first mar- 
gined. Lamellz remote. Spores .0064.0046 mm. 
In pastures and meadows. Pileus 3-5 in. in breadth, stipe 5-9 in. 
high, of the size of the preceding species ; it is also of the same red- 
dish-brown color. But it is not umbonate, the disk being depressed , 
or somewhat umbilicate ; the flesh srows reddish after being broken 
or bruised ; the stipe is never spotted. According to Worthington 
Smith’s measurement, there is a great difference in the size of the 
spores. Prof. Peck expresses doubts as to this species being found 
in this country, but I have had specimens which I confidently referred 
here. 
b’. Pileus white or whitish. 
10. A. MorGANI, Peck.—Pileus fleshy, soft, globose, then explanate ; 
the cuticle breaking up into seceding scales. Stipe cobwebby-stuffed, 
somewhat bulbous, tapering upward. Lamelle remote, at first white, 
then changing to greenish. Spores subelliptic greenish, .010-.012* 
.007-.008 mm. (See Plate II.) 
Open, dry, grassy grounds, in pastures and along the roadsides. 
Pileus white, or the cuticle alutaceous, commonly 5-9 in. in diameter, 
the stipe 6-8 in. long, though larger specimens are sometimes found. 
This is the most conspicuous Agaric in the meadows and pastures of 
the Miami Valley ; it appears to flourish from spring to autumn when- 
ever there is abundance ofrain. It is readily recognized by its green 
spores, by which it is remarkably distinguished from all other Agarics.

1879, also note by the writer in the September namber. 
11. A. mAstorpEus, Fr.—Pileus somewhat fleshy, soft, ovate-expand- 
ed, umbonate; the umbo prominent; cuticle thin, seceding in papille. 
Stipe hollow, slender, tapering equally from the bulb. Lamelle very 
remote, pallid. 
About old stumps in open woods. Pileus 14-24 in. across, stipe about
