vaticus that its being a dwarf form of the latter seemed more than prob- 

 able. Its edible qualities are the same. 



A. Rod'mani Pk. Pileus rather thick, firm, at first convex, then 

 nearly or quite plane, with decurved margin, smooth or rarely slightly 

 cracked into scales on the disk, white or whitish, becoming yellowish 

 or subochraceous on the disk, the flesh white, unchangeable. Lamellae 

 close, narrow, rounded behind, free, reaching nearly or quite to the 

 stem, at first whitish then pink or reddish-pink, finally blackish-brown. 

 Stem short, subequal, solid, whitish, smooth below the ring, often 

 scurfy or slightly mealy-squamulose above; ring variable, thick or thin, 

 entire or lacerated, at or below the middle of the stem. Spores broadly 

 elliptical or subglobose, generally uninucleate, 5-6x4-5^. 



Plant 2-3 in. high. Pileus 2-4 in. broad. Stem 6 10 lines thick.

This species is intermediate between A. campestris and A. arvensis, 

 from both of which it may be distinguished by its narrow gills, solid stem 

 and smaller, almost globose, spores. In size, shape of the pileus and 

 general appearance it most resembles A. campestris, but in the whitish 

 primary color of the gills and in the yellowish tints which the pileus 

 often assumes, it approaches nearer to A. arvensis. Peck,

I can now add my own testimony to that of Mr. Rodman as to its 

 edibility. Its flesh is firm but crisp, not tough, and its flavor, though 

 not equal to that of the common mushroom, is nevertheless agreeable, 

 and its use as food is perfectly safe. Peck, Rep. 49. 



This species has grown freely for several years at Hull and Cohasset, 

 Mass. It is usually found about June ist, and is not seen again until 

 early autumn. It is the handsomest mushroom I have seen, and its 

 edible qualities are on a par with its appearance. Macadam. 



A. hsemorrhoida'rms Shulzer. Gr. discharging blood. Pileus 4 

 in. across, reddish-brown, fleshy, ovate then expanded, covered with 

 broad adpressed scales, margin at first bent inward. Flesh when broken 

 immediately blood-red. Stem 4 in. high, I in. thick, soon hollow, 

 fibrillose, the solid base somewhat bulbous. King superior, large. Gills 

 free, approximate, crowded, rosy-flesh-color, at length purple-umber.
