Murrill: Clitocvbe in North America 
275 
First described as a variety of C. dealbata from specimens 
collected in grassy ground at Saratoga, New York, by F. G. 
Howland. It has been collected in two or three other localities in 
Albany and Ontario Counties. Mr. Howland, Dr. Peck, and 
Dr. W. W. Ford all agreed that this mushroom was decidedly 
sudorific and unwholesome, differing decidedly in this respect 
from the reputation enjoyed by C. dealbata. I have examined 
the types, however, and can see no morphologic difference 
between the two plants. They both grow gregariously in exposed 
grassy places and the best observer could not tell them apart. 
See notes on C. morbifera Peck. 
Clitocybe sulphurea Peck, Ann. Rep. N. Y. State Mus. 41 : 
62. 1888 
Described and known only from specimens collected on decay- 
ing wood of spruce and balsam fir on Wittenberg Mountain in 
the Catskills, New York. There are five rather young specimens 
on the type sheet at Albany. They appear to be related to Cor- 
tincllus decorus, but the surface is not squamulose. 
Clitocybe trullisata (Ellis) Sacc. Syll. Fung. 5:195. 1887 
Agaricus {Clitocybe) tridlisatus Ellis, Bull. Torrey Club 5: 45. 
1874. 
Described from specimens collected in an old sandy field at 
Newfield, New Jersey, and later reported in sandy soil in Suf- 
folk, Nassau, Madison, and Albany Counties, New York. Peck 
remarks that the species resembles larger forms of Laccaria 
laccata, but it has a stouter habit, the pileus is more squamulose, 
the stipe is bulbous, the mycelium violet-colored, and the spores 
oblong. The spores are described as oblong or cylindric, smooth, 
granular within, 15-20 X 8-9 /a. 
Clitocybe tenebricosa sp. nov. 
Pileus convex, becoming depressed at the center with the 
margin upturned, gregarious, reaching 6 cm. broad ; surface 
smooth, white, glabrous ; context white, rather thin, without 
characteristic odor ; lamellae crowded, somewhat ventricose.
