The Mycologic Flora of the Miami Valley, 0. 61 



Along the borders of woods and in pastures. Pileus 3-5 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. RHACODES, 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. Lamellae remote. Spores .0064X-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 grows 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. 



h'. 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. Lamellae remote, at first white, 

 then changing to greenish. Spores subelliptic greenish, .010-.012X 

 .007-.008 mm. (See Plate IL) 



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 of rain. It is readily recognized by its green 

 spores, by which it is remarkably distinguished from all other Agarics. 

 See article by Prof. Chas. H. Peck, in Botanical Gazette, for March, 

 1879, also note by the writer in the September number. 



11. A. MASToiDEUs, Fr.— Pilcus somewhat fleshy, soft, ovate -expand- 

 ed, umbonate; the umbo prominent; cuticle thin, seceding in papillaj. 

 Stipe hollow, slender, tapering equally from the bulb. Lamellae very 

 remote, pallid. 



About old stumps in open woods. Pileus 1^-2^ in. across, stipe about
