pale then dusky or brownish ; s. stout, short, equal, slightly thickened at the base, 
solid, whitish, distinctly cortinate, silky-fibrillose, 2-3 cm. ; sp. pip-shaped, smooth, 
9-1 ix 5-6 /x; c. slightly ventricose, 65-75 x 12-16 n, abundant. Flesh white, not 
changing colour. 
On the ground in coniferous and mixed woods. Britain, France, Germany, 
Sweden, Denmark, Holland. 
The above agrees with the species as understood by Fries, and represented as 
/. scabra in Roum., Fung. Gall., exs. 1902, and Rabenh., Fung. Eur. 1902. 
This Fungus is much more sturdy and with a thicker stem than other allied 
species. The species may practically be considered as originating with Fries, for 
although he quoted Muller’s figure and adopted his name, there is really nothing 
to prove that the species accepted by Fries was the plant so named by Muller, whose 
brief description is as follows 
‘ Agaricus scaber lamellis et dipile albis , pileo hemispherico fusco , squamoso! 
Muller’s figure represents a group of quite young specimens, and does not 
suggest anything very definite. 
pyriodora, Karst., Hattsv., p. 456; Sacc., Syll. v, p. 7 66 ; Cke., 111 ., pi. 472; 
Bres., Fung. Trid., tab. lii ; Agaricus pyriodorus, Pers., Syn., p. 300. 
P. ovate, then campanulate, at length expanded and umbonate, pale ochre, 
sometimes reddish when young, 4-7 cm.; g. adnate then rather rounded behind, 
thin, crowded, brownish, edge whitish ; s. solid, nearly equal, often curved near the 
base, fibrillose, pallid, apex with white meal, flesh reddish when cut ; sp. pip-shaped, 
apiculate, smooth, 9-10 x 5-6 /x; c. variable in form, ventricose or clavate, 40-50 
X 15-17 scattered. Smell pleasant, resembling ripe pears. 
In woods. Britain, France, Germany, Austria, Sweden, Russia, Finland, United 
States (Waynesville, Ohio, T. G. Lea, 1844). 
Odour penetrating, like that of rotten pears or Hyacinthus racemosus (Berk.). 
The above diagnosis accords with what is universally accepted by mycologists 
as the species of Persoon. 
rimosa, Karst., Hattsv., p. 462 ; Sacc., Syll. v, p. 775 ; Ag. rimosus, Bull., 
Champ. Fr., tab. 388 ; Ag. ( Ino .) rimosus , Cke., 111 ., pi. 384. 
P. campanulate, sometimes subumbonate, silky-fibrous and becoming cracked 
from disc to margin, yellowish-brown, 2-5-5 cm.; g. almost free, somewhat crowded 
and ventricose, dingy tan ; s. equal, firm, nearly smooth, whitish, apex mealy, 
4-7 cm. ; p. pip-shaped, smooth, 12-15 X 7 /i;c. ventricose, scattered, 60-65 x 15-18/x. 
Smell earthy. 
On the ground in woods. Britain, France, Germany, Sweden, Russia, Finland, 
Holland. 
Differs from I. aslerospora and I. fasiigiata in the smooth spores. I. euiheles is 
separated by the adnate gills and umbonate pileus, and I. pyriodora by the strong smell. 
One of the old species about the identity of which practically all are agreed. 
It is represented in C. Roumeg., Fung. Sel., exs. 5306 ; Roumeg., Fung. Gall., exs. 
1302 and 3813; Sydow, Myc. March, 2609.
