This is a good species in every way. I have not found it in extended quantity, but it is probable that it will be found in plenty when closer observed and better known.
P. circina´tus Fr.—to make round. Wholly white, not hygrophanous. Pileus about 3 in. broad, orbicular, horizontal, fleshy, tough, convex then plano-disk-shaped, obtuse, even, but covered over with a shining whitish slightly silky luster. Stem 1–2 in. long, 3–4 lines thick, stuffed, elastic, equal, central or slightly excentric, commonly straight, smooth, bluntly rooted at the base. Gills adnate, slightly decurrent, crowded, broad (as much as 3 lines), white. Fries.
An exceedingly distinct species. Regular, solitary, with a weak, pleasant, not mealy odor. The pileus is a little thicker than that of A. lignatilis, but less compact; the gills are twice as broad. As A. lignatilis is changeable, this is always constant in form.
On rotting birch stump. Stevenson.

Found at Eagle’s Mere, Pa., August, 1898, on birch trees. Generally solitary; sometimes six or eight on one tree, beautifully shining white, at a distance resembling young Polyporus betulinus. Large quantities of it grow in the extensive birch forests at Eagle’s Mere, yielding a ready food supply. Its flavor is pleasant, and texture, when cooked, quite tender.
P. pubes´cens Pk.—pubes, down or soft hair. Pileus fleshy, convex, suborbicular, pubescent, yellowish. Gills broad, subdistant, rounded behind, sinuate, pallid tinged with red. Stem short, firm, curved, eccentric, colored like the pileus. Spores globose, 8µ broad.
Pileus about 2 in. broad. Stem scarcely 1 in. long.
