New Species of Fungi. 
. By Cuas. H. PEcK. 
LEPIOTA MUTATA. 
Pileus thin, convex, subumbonate, slightly scabrous on the disk, 
white, changing to brown on the disk in drying ; lamellae close, 
thin, subventricose, free, white; stems slender, equal, hollow, 
white ; the annulus slight, sometimes evanescent; spores ellip- _ 
tical, .0003 to .o004 in. long, .0002 to .00024 broad; pileus 1 to 
1.5 in. broad; stem about 1 in. long 1 to 2 lines thick. 
Ground in woods. Kansas. July. E. Bartholomew. 
In the fresh condition this plant is entirely white, but in the 
dried specimens the umbo or disk has become brown. This 
change in color suggests the specific name. In the other white 
Species, ZL. evminea and L. alba, the spores are longer, and in ZL. 
Miamensis and L. subremota the pileus is scaly. 
CLITOCYBE SUBSOCIALIS. 
Pileus fleshy, convex, becoming somewhat depressed centrally, 
minutely squamulose, pale tawny or subrufescent, flesh white, 
taste and odor nauseous; lamellae subdistant, decurrent, white, 
the interspaces venose ; stem equal, solid, colored like the pileus, 
having a white mycelioid tomentum at the base; spores subellip- 
tical, .00024 to .0003 in. long, .00016 to .0002 broad, slightly apicu- 
late at one end and usually containing a shining nucleus ; pileus 
6 to 18 lines broad ; stem I to 2 in. long, I to 2 lines thick. 
Grassy ground. . Camas, Washington. December. F. C. 
Yeomans, ; 
The species is apparently closely allied to Ciitocybe socialis, 
from which it differs in its strong odor, squamulose pileus and 
White lamellae. It also approaches C. sinopica and C. infundibli- 
Jormis in color, but in both these the pileus is also glabrous. The 
Squamules are somewhat granular in appearance. 
OMPHALIA LUTEOLA. 
Pileus thin, convex or sub-hemispherical, glabrous, centrally 
€Pressed or broadly umbilicate, buff-yellow ; lamellae few, 10-15, _ 
distant, decurrent, pallid; stem slender, glabrous, solid, brown, — 
with white mycelium at the base; spores subelliptical, .00024— 
00028 in long, about .o0016 broad, commonly uninucleate ; pileus 
_ 2-4 lines broad ; stem about 6 lines long, .5 thick. = ae
