186 CRYPTOGAMIA. FUNGI, Agaricus. Solid end Fixed. 
Wuire. - 
- glastticus, Ac. Gills white, 4 in a set: pileus chesnut, semi-globu- 
lar; stem buffy white, tapering. 
Schaef. 87.4. 5—(stem too red and too much ribbed.) Bull 
516.2, resembles it, but this plate is so far unfinished 
that I cannot quite decide until the text be' published, 
The author calls it fusipes, which he figured before in 
plate 106, but if it be only a variety of that, his own 
observations at the foat of the plate must prove unfounded. 
The smaller figures give a pretty exact idea of our plant, 
but the stems have too much colour. 
Guts fixed, whitish, 4 in a set. 
Pixevs chesnut colour, semi-globular, uniform, clothy, 
Flesh white, moderately thick. 
Stem solid, buff, with a few small red brown blotches, smooth, 
1} to 2 inches high, + inch diameter, tapering upwards 
from % inch above the ground, and from the same part 
rapidly tapering downwards so as to end in a slender 
Toot; sometimes rather ribbed. 
This Agaric is very tough and. strong, with a considerable 
share of elasticity. Mr. Stackhouse observes that the edge of 
the pileus coops in like the button of a common mushroom, that 
the gills are numerous, stiff, and white, that it is often found not 
in clusters, and that in many instances it approaches the Ag. 
crassipes. To this opinion I perfectly agree, and further remark, 
that the tendency to a ribbed stem in some of the specimens still 
increases the affinity ; but until the Ag. crassipes shall be better 
known, especially in its yonnger and smaller forms, I think the 
difficulties will sooner be cleared up by keeping them apart. 
The want of a boss on the pileus, the absence of cracks in its 
skin, the want of strongly marked ribs on the stem, and more 
than all, the tough elastic substance of the plant, prevent me at 
present from arranging it as a variety of the crassipes.
