Pileus convex, dry, at first compact and minutely ¢omen- 
tose, then squamose or smooth, reddish or orange-red, the 
margin appendiculate with the inflexed remains of the mem- 
branous veil, flesh white or grayish; tubes at first concave 
or nearly plane, almost or quite free, minute, sordid-white, 
their mouths gray; stem equal or tapering upward, solid, 
rugose-squamose, whitish or pallid; spores oblong-fusiform, 
.00055 to .0007 in. long, .00016 to .00025 broad. 
Pileus 2 to 6 in broad; stem 3 to 5 in. long, 4 to 10 lines 
thick.

The fragments of the membranous veil, which adhere to 
the margin of the pileus, afford the most available character 
by which to separate this species from Loletus scaber. The 
prevailing reddish or orange hue of the pileus scarcely dif- 
fers from that of var. aurantzacus of that species. In 
American specimens the stem is precisely alike in both 
species. Fries says that the two appear to be distinct but 
are defined with difficulty on account of analogy in color 
and variation in stature. It is recorded as edible, but Gil- 
let says it is scarcely to be commended.
