Equal to P. cervinus.
P. umbro´sus Pers.—shady, from its dark color. Pileus fleshy, at first bell-shaped, then convex or expanded, roughly wrinkled and more or less villose on the disk, fimbriate on the margin, blackish-brown. Gills broad, somewhat ventricose, at first whitish, then flesh-colored, blackish-brown and fringed or toothed on the edge. Stem solid, colored like or paler than the pileus, fibrillose or villose-squamose. Spores elliptical, 8×5µ.
Decaying woods and swamps, especially of pine, both in shaded and open places. Not rare. Peck, 38th Rep. N.Y. State Bot.
Spores broadly elliptical, smooth, 6–7×5µ; cystidia ventricose, 65–75×18–20µ Massee.
New York, Peck, Rep. 32, 38; West Virginia, Pennsylvania, North Carolina, New Jersey, frequent on decaying logs, stumps, pine and other woods. McIlvaine.
At times the caps are a deep sepia-brown. It is readily distinguished from P. cervinus by the wrinkled, downy disk of the cap and the gills having dark-brown edges. Smell rather strong. Professor Peck says he has not seen it with the margin fimbriate. Neither have I, though this is prominent in the European species.
P. umbrosus is a fine species, equal in every way to P. cervinus, which is seldom excelled. Caps only are tender.
P. pelli´tus Fr. Pileus 1–2 in. across. Flesh thin, soft, white, convex then plane, somewhat umbonate, regular, silky-fibrous, dry, white. Gills free, rounded behind, crowded, 1½ line broad, ventricose, white then flesh-color, margin slightly toothed. Stem about 2 in. long, 2–3 lines thick, slightly thickened at the base, even, glabrous, shining, white, stuffed. Spores elliptical, smooth, 10×6µ.
Among grass at the roots of trees, etc.
Our only Pluteus with a pure white, even pileus and stem. Superficially resembling Entoloma prunuloides, which differs in the broadly emarginate—not free—gills, and in the strong smell of new meal. Massee.
