The disk has something the appearance of a scar ; hence the specific 
name. 
Inocybe echinocarpus, E. & E. (N. A. F., 1904.) On the ground 
in an old abandoned road among oak bushes, September-Oetober. 
Pileus conic-convex, not readily expanding, l^-2 cm across, pilose- 
squamose, disk broken up into stouter scales similar to those of Hijd - 
num imbricatum , color tawny yellow. Lamellae subveutricose, rounded 
behind and narrowly attached or nearly free, scarcely crowded, dirty - 
pallid, becomingclouded by the ferruginous spores, margins whitish and 
nearly entire. Stem 2J cm long, 2-3 mm thick, solid, of fibrous texture, 
tough (bends short without breaking), farinose-floccose above, sub- 
attenuated and slightly silky-fibrillose below, a little darker than the 
pileus. Spores- echinate (not simply angular or tuberculose), but thickly 
beset with short spines, irregularly globose or a little elongated, 8-11//, 
diameter on subveutricose basidia about 30 by 10//, with stout, slightly 
spreading sporophores 4-5// long. 
This is a well-marked species, easily recognized by its echinate spores, 
broad basidia, and coarsely squamnlose disk. There is no sterile pro¬ 
jecting margin to the pileus, the ventricose gills coming out full to the 
margin. The measurement of the spores includes the length of the pro¬ 
jecting spines and is mostly 8-10//, exceptionally 11//. This differs 
from A. stellatosporus , Pk., in its larger echinate spores and stem not 
scaly. 
Inocybe sitbdecurrens, E. & E. (1ST. A. F., 1906). On the ground 
under the overhanging branches of Norway spruce, September-No- 
vember. 
Densely gregarious. Pileus 4-5 cm across, convex, expanding to plane, 
with disk depressed and either nmbonate or not, but oftener without 
any umbo, surface densely and evenly appressed-pilose, color yellow- 
drab, fiesh thin. Lamellae moderately close, adnate-decurrent, pale 
dirty cinnamon, not changing much in color with age, about 3 n,m wide, 
margins serrulate. In the mature plant the lamellae are very slightly 
ventricose, but never depressed around the stem. Stem mostly straight, 
sub equal, hollow , fibrillose-squamose above, covered with loose white 
silky fibres below and white tomentose at base, 3-4 crn high, £-| c,n thick, 
moderately tough. Spores elliptical, rounded at both ends, without 
any distinct apiculus, ferruginous cinnamon, 8-10 by 4-5// on basidia, 
about 25 by 7-8//. The stem is not simply fistulose, but in all mature 
specimens hollow. 
This has been found in the same place in great abundance now for 
three years in succession. 
Inocybe tomentosa, E. & E. (N. A. F., 2101). O11 the ground in 
grass, around and partly under the overhanging branches of Norway 
Spruces, at a short distance from the preceding species, but not mixed 
with it. July-September, 1888. 
Gregarious and sub-cespitose. Pileus piano convex, depressed in the 
center and generally with a small umbo, 2-4 c,u across, margin at first
