up with age: central boss pale reddish brown, border darker brown with 
a purple tinge ; one and a half to two inches over.

Ag. suB-CiERU^EUS. Gills whitish, numerous, four or eight in a set: 
pileus convex, centre brown, edge blue : stem pale brown: root 
large, bulbous. 
Gills slightly connected with the stem, nearly white, slightly and irregularly 
serrated at the edges, the serratures most obvious in the older plants, 
four or eight in a set. 
Pileus convex, brown in the centre, bluish at the edge, elsewhere pale buff, 
or almost white, smooth, one and a half to two inches over. 
Stem hollow, but the hollow partly filled with loose pith, pale brown, cylin¬ 
drical, smooth, cottony at the base, two inches high, thick as a goose quill. 
Root a large bulb, covered with a white cottony substance, and dead 
leaves adhering to it. 
In some plants of smaller growth the edge of the pileus is more turned in, 
giving a rounder shape to the whole of it, and the purple tint is more 
equally diffused.

Ag. purpu'reus. (Bolt.) Gills white, four in a set: pileus purplish, 
somewhat bossed: stem cylindrical, purple. 
Bolt . 41. B— Batsch. 20. very like our plant, hut the stem thicker, and neither 
the drawing nor the description speak sufficiently to the structure. 
Gills fixed, white or purplish white, four in a set, uneven at the edge, mo¬ 
derately numerous, smaller series very small, sometimes one wanting. 
Pileus bluish white or purple, changing to yellow brown, gently convex, 
or nearly flat, but always more or less of a central boss, turning up at the 
edge with age, smooth, half to one inch over. 
Stem hollow, red purple, cylindrical, thick as a crow quill, one and a half 
to two inches high. Curtain purplish, composed of threads like a cob¬ 
web, vanishing when the plant is yet young. 
The purple colour of the stem is the same within as without; that of the 
pileus is very evanescent. Notwithstanding the difference of size, &c. 
it may possibly be only a variety of the preceding species.

brown.

by cross threads. 
Pileus pale brown, flat, bossed, thin, centre deeper brown, one inch and a
