malis but can be distinguished by the broad,
ovate gills bearing cystidia, and smaller spores.

_Mycena hiemalis. Osbeck._

THE WINTER MYCENA.

Hiemalis, of, or belonging to, winter. The pileus quite thin,
bell-shaped, very slightly umbonate, margin striate; pinkish, rufescent,
white, sometimes pruinose.

The gills are adnate, linear, white or whitish.

The stem is slender, curved, base downy, whitish, pinkish-red. The
spores are 7-8x3.

This is a more delicate species than M. corticola and differs from it in
its narrow gills, and striate, not sulcate, pileus, also in the color of
the stem. Found on stumps and logs. October and November.

_Mycena Leaiana. Berk._

[Illustration: Figure 94.--Mycena leaiana. Natural size. Caps bright
orange and very viscid.]

Leaiana named in honor of Mr. Thomas G. Lea, who was the first man to
study mycology in the Miami Valley. This is a very beautiful plant
growing on decayed beech logs in rainy weather. The pileus is fleshy,
very viscid, bright orange, the margin slightly striate as will be seen
in the one whose cap shows.

The gills are distant, not entire, broad, notched at the stem, attached,
the edge a dusky orange, or vermilion, the short gills beginning at the
margin.

The stem is in most cases curved, attenuated toward the cap, smooth,
hollow, rather firm, quite hirsute or strigose at the base. The spores
are elliptical, apiculate, .0090x.0056 mm.

They are caespitose, growing in dense tufts on logs somewhat decayed. It
is extremely viscid, so much so that your hands will be stained yellow
if you handle it much. It grows from spring to fall but is usually more
abundant in August and September. Very common.

_Mycena iris. B._

Pileus is small, convex, expanded, obtuse, slightly viscid, striate,
quite [blue?] when young, growing brownish with blue fibrils.

The gills are free, tinged with gray.

The stem is short, bluish below, tinged with brown above, somewhat
pruinose. Found in damp woods after a rain, in August.

_Mycena pura. Pers._

[Illustration: _Photo by Prof. G. D. Smith._

Figure 95.--Mycena pura.]

Pura means unstained, pure.

The pileus is fleshy, thin, bell-shaped, expanded, obtusely umbonate,
finely striate on the margin, sometimes having margin upturned, violet
to rose.

The gills are broad, adnate to sinuate, in older plants sometimes free
by breaking away from the stem, connected by veins, sometimes wavy and
crenate on the ed
