gluten, the spores also are of the same size but the stem is pale yellow 
above, livid below and fibrillose scaly. The species appears to be very 
close to Stropharia aeruginosa. W. G. Stover suggests that it is a 
form of Flammula polychroa. 
The Stropiiaria Coeoxilla -Group. 
Stropharia coronilla, Bull. PI. LXV A. 
The plants illustrated grew on the ground in the grass near 
a garden, Madison, Wis., June, 1911. The general appearance 
is like that of Pholiota dura and the place of growth is similar 
so that the plants might easily have keen taken for that species, 
but there is no rusty tinge to the spores and the annulus has the 
ridges characteristic of Stropharia coronilla. 
Pileus fleshy, firm, hemispheric to convex and expanded, 
smooth and slightly viscid, even and white floccose on the mar¬ 
gin, sometimes appendiculate with pieces of the veil, whitish 
or yellow ochraceous, darker in the center. Lamellae broad, 
rounded and adnexed or very slightly notched at the stem, 
whitish becoming violet and purple black. Flesh firm, solid, 
white. Stem even or tapering slightly upward and narrowed 
to a point below, solid or stuffed, smooth, white or with yellow¬ 
ish tints. 4nntjltjs thick easily separating from the stem, 
sometimes adhering to the margin of the pileus, floccose below, 
with radiating ragged ridges on the upper surface which are 
at first white then stained purple from the falling spores, 
Spores purple brown or black 4—Gx9—12 /l 
In FT. Y\ State Mus. Bull. 122, p. 140, Dr. Peck gives a 
comparison between Stropharia bilamellata and Stropharia 
coronilla. Our plants agree with Stropharia bilamellata in the 
white or yellowish rather than the tawny ochraceous pileus, but 
in the other points of the comparison, stem pointed at the base, 
annulus sulcate plicate rather than with broad white gills, and 
smaller spores, our plants agree with Stropharia coronilla, 
hence we do not hesitate to refer them to the European species. 
The species is distributed in FT. A. F. 3511. My copy shows 
spores 5—6x8—IV and the peculiar annulus.
