279 
in diameter. The hymenophore is very variable in color, ranging 
from pale-yellow to orange; the taste is astringent and unpleasant 
at first, soon becoming nutty and less unpleasant, though the 
astringent effects remain.

Clitocybe microspora Peck, Bull. Torrey Club 36:331. 1-909 
Described from specimens collected by C. F. Baker at Clare- 
mont, California, in January. Peck says it is related to C. eccen- 
trica, but is larger, with less crowded lamellae, hollow stipe, 
smaller spores, and the pileus never umbilicate. 
Clitocybe pusilla Peck, Bull. Torrey Club 22: 199. 1895 
Known only from specimens collected by IMcClatchie on manure 
at Pasadena, California, February 15, 1895. The type, or at 
least a portion of it, is in McClatchie’s herbarium at the New 
York Botanical Garden, numbered 879. 
Clitocybe sinopica (Fries) P. Karst. Bidr. Fink Nat. Folk 
32: 73. 1879 
I found this species both in woods and in open fields. Its 
farinaceous odor was very distinct. The colors of the pileus and 
stipe were found to vary considerably.

Clitocybe subsocialis Peck, Bull. Torrey Club 23:411. 1896 
Described from specimens collected by Yeomans on grassy 
ground at Camas, Washington, in December. Peck remarks that 
it is closely related to C. socialis, but differs in its strong odor, 
squamulose pileus, and white lamellae. The types at Albany 
very much resemble C. sinopica, but Peck says they differ from 
this species in their squamulose surface, although resembling it 
in color.
