322 NORTH AMERICAN SPECIES OF MYCENA

New York, August 5, 1902, C. H. Peck & F. S. Earle 839 (herb. N. Y.
Bot. Gard.).
"Distribution: Long Island, New York, Louisiana."
This is the original account of the fungus. I have examined the
type and found the spores to measure 5-6 (7) X 4-5,. They are
broadly ellipsoid to subglobose, smooth, and weakly amyloid. Occasionally small oil droplets have accumulated around the periphery
of the spores and caused them to appear very minutely echinulate.
The gill trama and that of the pileus did not revive very well, but
both turned yellow in iodine. The pileus trama appeared to be
practically homogeneous beneath a thin pellicle, and no cystidia were
observed on the gills or the pileus. The species appears to be well
characterized by its small, very broadly ellipsoid, weakly amyloid
spores and its lack of cystidia.

Pileus 1-2 (4.5) cm. broad, conic to convex or with a low subconic
umbo, remaining broadly conic or convex, often with a small papilla,
rarely slightly depressed, margin connivent to the stipe when young,
opaque, becoming closely striate to near the disc at maturity, surface
lubricous or subviscid in age or when wet, at times distinctly viscid,
glabrous, when young pale fuscous gray to watery gray on the disc
and whitish toward the margin, at times the disc pale bluish gray,
soon fading and whitish over all, with a tendency to become creamcolored or stained tawny in age; flesh thin, flaccid, and cartilaginous,
white, odor and taste not distinctive; lamellae broadly adnate-subdecurrent, close, 22-25 reach the stipe, broad (3-4 mm.), white, or
occasionally flushed pale incarnate, edges even; stipe 2-5 (10) cm.
long, 1-2 mm. thick, equal, cartilaginous and brittle, tubular, glabrous
except for the white-strigose, somewhat rooting base, when young
bluish gray toward the apex and whitish below, soon fading to watery
grayish white over all, lubricous to somewhat viscid.
