The pileus is fleshy, one inch broad, conic, or bell-shaped, somewhat umbonate, obtuse, whitish to flesh-color, with more or less dull red, even, or slightly striate at the margin, the margin extending beyond the gills and is toothed.
The gills are attached to the stem, often with a decurrent tooth, whitish. Spores, 10×6–7.
The stem is two to four inches long, firm, hollow, sometimes smooth, sometimes powdered with whitish, soft hairy down, in color the same as the pileus, yielding a dark red juice which gives name to the species.
The color varies quite a little in these plants, owing to some having more of the red juice than others. The genus is readily identified by the dull blood-red juice, hollow stem, the crenate margin of the cap, and its dense cespitose habits. It is found on decayed logs in damp places from August to October. The plants in Figure 90 were found in Haynes' Hollow, September 8. The plant is widely distributed over the United States. No one will have the slightest difficulty in recognizing this species after seeing the plants in the figure above.

The Stump Mycena.
Figure 91.—Mycena alkalina. Two-thirds natural size, often larger. Young specimens.
Solitary or cespitose; pileus one-half to two inches broad, rather membranaceous, campanulate, obtuse, naked, deeply striate, moist, shining when dry, when old expanded or depressed, but little changed in color, though occasionally with a pink or yellow hue, whitish or grayish, the center of the disk darker.
