North American species of Mycena.

EUMYCENA: TYPICAE

341

Also collected in similar situations in November and December, 1932
(F 15692, F 15693, F 15709 and F 15695). A fine species, abundant
at times on oak logs, suggesting M. galericulata and M. inclinata."
Through the kindness of Dr. Murrill I have been able to examine
material collected by him at Gainesville, November 7, 1938. The
spores were found to be strongly amyloid and broadly ellipsoid, and
to measure 5-7 X 4.5-5.5 j. The basidia are four-spored. Cheilocystidia of the clavate-echinulate type are present, but are not conspicuous and measure 28-34 X 6-9 M. The pileus and gill tramae
are strongly amyloid and similar in organization to those of M. inclinata. The white stipe and small spores distinguish it from M.
inclinata and the cheilocystidia from M. pseudoinclinata. It is also
close to M. hemisphaerica, but the color of the stipe should distinguish
it. Since I have not seen fresh material I hesitate to refer M. subinclinata to synonymy with M. hemisphaerica. Spores from deposits
should be compared to see if the apparent difference in size is
constant.

Pileus (1) 2-4 (5) cm. broad, varying in shape from obtusely conic
to convex at first, soon expanding to campanulate or broadly convex,
at maturity more or less expanded, usually with a distinct umbo,
umbo abruptly conic in some and very broad and low in others,
margin connivent to the stipe when young, sometimes flaring or recurved in age, surface glabrous, lubricous, often opaque when young
but becoming translucent-striate nearly to the disc before fading,
often somewhat wrinkled or sulcate-striate in age, colors sordid
blackish brown or nearly black at first, becoming paler sordid brown
to brownish gray in age and nearly always with sordid reddish-brown
spots ("light seal brown" to "snuff brown" when young, becoming
"hair brown" to "avellaneous" or pale "vinaceous buff," the margin
frequently "smoke gray" or paler watery gray in age, some collections
