DISTINGUISHING FIELD-MARKS: Although this is much the 
same color as L. grisea, it can readily be distinguished from it by 
the absence of tomentum, by the striate margin, and the pungent, 
aromatic odor, which persists for some time. Тһе pileus is only 
faintly squamulose, and sometimes seems to be merely roughened 
and unpolished. It is never floccose-squamulose like the pileus 
in mature forms of L. grisea. 
According to Fries, the color is sometimes brick-red and again 
has a violet tinge, but this has not been observed in the American 
forms.

DisrRiB.: Massachusetts, Hibbard. 
DISTINGUISHING FIELD-MARKS: This species may be distin- 
guished from ZL. g/yciosma, which it most closely resembles, by the 
tomentose rather than squamulose pileus, the faint zonation, the 
absence of the odor peculiar to that plant, and by the tomentum 
on the stem. 
The type specimens are in the herbarium of the N. Y. State 
Museum at Albany.
