North American species of Mycena.

140 NORTH AMERICAN SPECIES OF MYCENA

"Stem slender, 4-6 cm. long, scarcely 1 mm. thick, pale, but with
a slight red tint, very minutely downy, attached by a circle of fibers
to pine needles at the base, exuding a dark red juice when wounded.
"Spores narrowly ellipsoid, 4 X 11-12 u. Cystidia abundant
on the margins of the gills, globose to rounded obovate with pointed,
rod-like projections.
"This interesting species was found once growing in abundance
on the fallen needles under pines. Unfortunately, the photograph
which was made was not successful and there was no other opportunity to make one. The drawing made at the time will show its
peculiarities and it will be readily recognized by its unusual characters.
In many ways this species is suggestive of Omphalia. The broad gills
which seem quite decurrent as the cap becomes expanded would
almost indicate its reference to that genus. In its bleeding stem,
margined gills, and setulose cystidia it finds, however, close relatives
in Mycena and it has seemed best to place it with these and ignore the
somewhat decurrent gills."
This is the original description and comments. Mr. Beardslee
has shown me the drawings of the microscopic characters as he made
them from the study of the fresh specimens. The pileus is corticated
by a palisade of pear-shaped hells. This is an additional important
character which, along with the others, justifies the specific name.
The species is as peculiar in the Lactipedes as M. rorida is in the
Glutinipes.
