=H. pena´rius= Fr.—_penus_, food. =Pileus= _tan-color, opaque_, fleshy, especially when young, at first umbonate, then very obtuse, hemispherical then flattened, even, smooth, _commonly dry_, margin at first involute, exceeding the gills, undulated when flattened. =Flesh= thick, hard, whitish, unchangeable. =Stem= curt, 1½ in. or more long, about ½ in. thick at the apex, _solid, compact_, hard, _attenuated at the base into a spindle-shaped root_, ventricose to the neck, again attenuated upward or wholly fusiform-attenuated, pale-white, smeared with tenacious, easily dried slime, _warty_. =Flesh= firm, but _externally more rigid_, cuticle somewhat fragile. =Veil= not conspicuous. =Gills= adnato-decurrent, acute behind, _distant, thick_, 3–4 lines broad, veined, tan inclining to pale. _Fries._ Odor pleasant, taste sweet. The fusiform root is as long as the stem. In mixed woods. _Stevenson._ =Spores= 7–8×4–5µ. Edible. _Cooke_. Large specimens occurred in mixed woods, in November, 1898, at Mt. Gretna. The caps varied from 1½-5 in. across. The color was white, tinged with yellow, much lighter than described. The caps look coarse and the stems are not inviting; but the caps have a pleasant odor. When stewed for twenty minutes they are meaty and tasty. ** _Reddish._ =H. erubes´cens= Fr.—_erubesco_, to become red. =Pileus= 2–4 in. and more broad, white becoming everywhere red, fleshy, gibbous then convexo-plane, viscid, _adpressedly dotted with squamules or becoming smooth_, sometimes wholly compact, sometimes thin towards the _margin which is at the first naked_. =Flesh= firm, white. =Stem= sometimes short, robust, 2 in. long, 1 in. thick and attenuated upward, sometimes elongated, 4 in. long, equal or attenuated at the base, _solid_, flexuous, _with red fibrils, dotted with red upward_. =Gills= decurrent, distant, _soft, white, with red spots_. _Fries._ Veil none. The ground color is white, as it is also internally, but it everywhere becomes red and the pileus often rosy blood-color. Handsome, growing in troops, commonly forming large lax circles. In pine woods. _Stevenson._ =Spores= ellipsoid, very obtuse at both ends, 8–10×4–5µ _K_.; 8×4µ _Cooke_. Edible. _Cooke._ *** _Tawny or yellow._ =H. ni´tidus= B. and Rav.—_shining_. =Pileus= thin, fleshy, convex, broadly umbilicate, smooth, shining, viscid, pale yellow with the margin striatulate when moist, nearly white when dry. =Gills= arcuate, decurrent, yellow. =Stem= slender, brittle, smooth, viscid, hollow, yellow. =Flesh= yellow. =Height= 2–4 in., breadth of =Pileus= 8–12 lines. =Stem= 1–2 lines thick. Swamps. Sandlake. August. The cavity of the stem is very small. _Peck_, 23d Rep. N.Y. State Bot. Found in many states and places, usually on moist ground beside streams, or spring heads. It sometimes parades itself in irregular processions, at others in sparse patches. It is delicate in flavor, and tender cooked.
