CRYPTOGAMIA. FUNGI. A garicus. 
149 
Pileus white, convex, a little bossed, sides plaited, very thin and semi¬ 
transparent, quarter to three-quarters of an inch over. 
Stem hollow, whitish, smooth, half to two and a half inches high, not 
thicker than a horse-hair in the smaller plants, nearly as thick as a crow- 
quill in the larger. 
The delicate structure of this plant causes it to tremble when held in the 
hand, as Haller has observed. The pileus has sometimes a little mouse- 
colour in its centre, and so has the stem in the larger plants towards the 
bottom. It dries when old, and then turns wholly of a brownish colour. 
Mr. Stackhouse once found, and figured one specimen with a ring on the 
stem. 
It is sometimes very minute. Stem not half an inch high, and a pileus not 
larger than the head of a pin. Baron Haller, Michelius, and others, are 
inaccurate in describing this species as sti'iated. That character, strictly 
speaking, ought to imply certain streaks or marks inherent in the pileus, 
whereas the striae which they allude to are nothing more than the edges 
of the gills appearing plainly through.

convex, concave when old: stem white.

Gills decurrent white. 
Pileus white brown, gently convex, turned up when old, about half to one 
and a half inch diameter. 
Stem solid, white, half inch high, the thickness of a pin. 
In Bolton’s figure the gills do not appear decurrent: Sibthorpe expressly 
tells us they are not, and yet he refers to the figure of Bulliard in which 
they are distinctly so.

Gills white, decurrent, not numerous, in pairs. 
Pileus white, smooth, from a quarter to one and a quarter inch diameter, or 
more, convex, or a little conical, edges turning up when old. 
Stem solid, white, from half to one and a half inch high, from the thickness 
of a small crow’s, to that of a swan’s quill. 
This Agaric varies much in its size, but it has in every state the appear¬ 
ance and the feel of ivory. In damp weather rather viscid, and in wet
