Harper—Species of Pholiota and Stropharia. 1021 
scribed and the large form mentioned. Stevenson gives 6x9/* 
as the spores measurements and Sylloge 5x8/* noticing also the 
larger measurements 6—8x12—16/* of Karsten and Britzel- 
mayr. The latter author has described what appears to be the 
small form with large spores as Stropharia submerdaria. Mor¬ 
gan has reported this species from Preston Ohio and considers 
it a form of Stropharia merdaria. 
We have collected what appears to be the same plant growing 
on dung at River Forest, Ills, and Blue Mounds, Wis. The 
photograph is from the River Forest specimens. Dr. Moffatt 
has also colected the plant at Wheaton, Ills. The description 
of Stropharia submerdaria is given in Revis. Hymenomyc, III, 
p. 13. “Pileus 3 cm. broad, hemispherical, umbonate or de¬ 
pressed, dull yellow, Stipe 6 cm long, 4 mm thick, base either 
attenuated or thickened, fibrous, white, annulus scanty, Lamel¬ 
lae not crowded, yellowish brown, often denticulate, Spokes 
brown with a violaceous tint, dark violaceous in mass, acute at 
one or both ends, 6—8x12—14/*.” 
Our notes give the pileus as “cream color or yellow, lighter 
on the margin, deeper yellow on the umbo.” Dr. MoffatPs 
notes read “dark watery brown when young and moist becoming 
pallid tan.” The stem is minutely white floccose becoming 
glabrate, annulus scanty. The photographs show scarcely any 
remains of the annulus. The dark violaceous brown, almost 
vinous color of the spores is characteristic. The plants have 
much- in common with Psilocybe coprophila, Bull, which also 
grows on dung, but has no trace of an annulus, the gills are 
slightly arcuate and the pileus is white and downy when 
'young. 
Stropharia stercoraria, Fr. PI. LXVIX. 
This, like all the other plants of the group, grows on dung or 
well manured ground. 
Pileus hemispherical becoming expanded, smooth, viscid, 
the viscid pellicle cracking as the pileus dries, even on the
