178 Peck : NEW SPECIES OF FUNGI 
A rare but peculiar species belonging to the section Clypeo- 
laria, but distinct and easily recognized by the dark but somewhat 
variable color of the pileus, of which the cuticle does not form 
scales but sometimes becomes radiately rimose on the margin. 
Tricholoma viscosum 
Pileus fleshy, convex, the irregular or wavy margin often 
turned upward when old, even, glutinous, shining when dry, yel- 
lowish tawny, darker or reddish brown in the center, flesh white, 
odor slight but unpleasant; lamellae narrow, close, nearly free, 
white ; stem firm, equal, brittle, solid, flexuous, glutinous, white 
above, brown below; spores minute, subglobose, 3-4 long. 
Pileus 2-5 cm. broad; stem 2.5—4 cm. long, 4—5 cm. thick. 
Low ground near St. Louis. August and September. N. 
M. Glatfelter. 
Clitocybe piceina 
Pileus fleshy, firm, convex or nearly plane, dry, white or 
whitish, tinged with gray when young, flesh compact, white, taste 
pungent, odor strong, disagreeable ; lamellae close, decurrent or 
sometimes strongly decurrent in lines running down on the stem, 
creamy white ; stem equal or nearly so, firm, stout, solid, subfibrous, 
commonly striate at the top with raised longitudinal lines ; spores 
globose, 5-6 # in diameter. 
Pileus 6-10 cm. broad ; stem 5-7 cm. long, 12-18 mm. thick. 
Under spruce trees near Chicago. September. ‘W. S. Moffat 
and L. H. Watson. 
In the dried specimens the pileus sometimes assumes a yellow- 
ish tint. The species is closely allied to C. cerussata and C. albis- 
stma. From the former it may be separated by its larger globose 
spores and from the latter by its whitish color being less clear and 
persistent. From both it differs in the more strongly decurrent 
lamellae, pungent taste and disagreeable odor. 
Collybia umbonata 
Pileus thin, conic becoming convex or nearly plane with de- 
flexed margin, prominently umbonate, glabrous, bay red or chest- 
nut color, sometimes darker in the center than on the margin, 
lamellae numerous, subdistant, narrowed toward the stem, nearly 
free, whitish ; stem rather long, glabrous, equal or slightly tapet 
ing upward, hollow, radicating, colored like or a little paler than 
the pileus ; spores minute, elliptic, 6-8 » long, 4-5 y broad. _ 
Pileus 2-3 cm broad; stem 5-15 cm. long, 4-6 mm. thick.
