P. silky-fibrillose, at length becoming squamulose around the margin, with 
a broad prominent disc, mouse-colour with a tinge of lilac when fresh and young, 
2-4 cm. ; g. adnate, rather broad, rusty with just a tinge of olive ; s. fistulose and 
soon hollow, fibrillose, about colour of p., 2-4 cm. ; sp. pip-shaped, smooth, 
8-9 x 4-5-5 n ; c. absent. 
On the ground in dry, bushy places. United States. 
The broad, prominent disc of the pileus either has a small umbo in the centre 
or a slight depression, and is generally surrounded (about half-way to the margin) 
with a distinct ridge or zone. The margin also projects slightly, and is a little lighter 
coloured and, under the lens, subfimbriate (E. and E.).

P. convex or plane, minutely hairy-tomentose, brownish-tawny, up to 2-5 cm. ; 
g. adnate, slightly emarginate, crowded, whitish then tinged olive, finally tawny 
brown, edge whitish, crenulate; s. short, solid, slightly silky-fibrillose, coloured like 
p., or a little paler, 2-5 cm. ; sp. elliptical, smooth, sometimes inclined to be curved, 
8-10 x 5-6 /x ; c. absent. 
Gregarious or subcaespitose. Gravelly soil among fallen leaves. United States 
(Rouse’s Point). 
Very closely allied to I. tomentosa ; however Peck considers the two as distinct, 
and distinguished as follows : — 
Differs from I. tomentosa by its darker colour, larger spores, and the entire 
absence of an umbo. Its prominent features are its small size, minutely tomentose 
pileus, and nearly uniform brownish-tawny colour when mature. /. fibrillosa by its 
solid merely fibrillose stem, and by the absence of scales on the disc of the pileus 
(Peck).

then dusky olive; s. subequal, solid, minutely fibrillose, paler than p., 5-10 cm. ;

As defined above, this Fungus is acknowledged as Ag.fastigiatus, Schaeff., by 
Qu^let, Karsten, Patouillard, Gillet, Bresadola, and Oudemans. Its prominent 
characters are the yellowish-brown pileus, olive gills, smooth elliptical spores, and
