A very distinct and well-marked species, but at the same time very variable in 
the colour of the pileus, which ranges from pure white, the commonest form, to 
yellow, lilac, violet, tawny, and brick-red. Some of these colour-forms have been 
quite unnecessarily considered as varieties, as var ,/ulvus, Pat., Tab. Anal., n. 544 ; 
var. vtolaceus , Pat., Tab. Anal, n. 545. The pileus is never truly squamulose. 
One of the old species on which all mycologists, up to the present, are agreed. 
As defined above it is represented in the following exsiccati : Rab., Fung. Eur., 10 ;

P. conical then convex, sometimes umbonate, fibrillose, tawny, margin whitish, 
then wholly pale tawny, slightly viscid, i*5-2*5 cm. ; g. adnexed, crowded, white then 
cinnamon ; s. solid, nearly equal, base slightly thickened, whitish and pulverulent, 
becoming brownish downwards, 3-6 cm. ; sp. pip-shaped, smooth, 9-1 1 x 4-5 /* ; 
c. fairly abundant, ventricose or almost cylindrical, 50-60 x 16-20/*. 
On the ground under conifers. Britain, United States (Catskill Mts.). 
Both Berkeley and Peck indicate the affinity of the present species with 
I. geophylla.

P. campanulato-convex, broadly umbonate, silkily downy when young, becoming 
almost glabrous, never fibrillose, when young the margin is appendiculate from the 
fibrils of the veil, white, pallid, or yellowish, 3-5 cm. ; g. slightly adnexed, narrow, 
brownish white ; s. soft, with a distinct pith then hollow, slightly fibrillose then 
glabrous, white, equal, 5-7 cm. ; sp. pip-shaped, smooth, 8-10 x 5-6 /* ; c. ventricose, 
50-60 X 12-16 /t. 
On the ground in damp, shady places. Britain, Germany, Sweden. 
Resembling I. geophylla superficially ; differing in the hollow stem, larger size, 
absence of earthy smell, &c.

P. conico-campanulate then expanded, edge usually slightly incurved, fibrillose, 
becoming radiately rimose and splitting when expanded, whitish or pale dingy brown, 
1 *5-2-5 cm.; g. almost free, somewhat crowded, white then brown ; s. almost hollow, 
equal, often slightly wavy, fibrillose, white, apex with white meal, fragile, 2-3-5 cm - 1 
sp. elliptic-oblong, sometimes slightly curved, apiculate, smooth, 8-10 x 5 /* ; c. ventri- 
cose, scattered, 50-60 x 12-16 /*. 
On the ground in woods. Britain, France, Sweden, Holland. 
A small species somewhat resembling I. geophylla , differing in the colour of the 
pileus and absence of a strong earthy smell. I have accepted, as typical of this 
species, specimens determined by Berkeley and figured by Cooke ( 111 ., pi. 428, top 
figs.). The colour of the pileus is too bright in these figures. 
Some authors give Ag. auricomus , Batsch, as a variety of this species. I have
