I frequently found this species in North Carolina, growing from oak ties and standing oak timber. I did not notice distillation of rufescent drops from the cap. The soft flesh had good flavor. The gelatinous cuticle imparts its character to the dish. Mixed with Lentinus lepideus, a much tougher plant, which grows in great abundance in the same localities, it makes toothsome food. =P. lignati´lis= Fr.—_lignum_, wood. Dingy whitish. =Pileus= 1–4 in. broad, rarely central, commonly more or less excentric, occasionally wholly lateral, often kidney-shaped, fleshy, thin, but compact and tough, fissile, convex then plane, obtuse and often umbilicate, _flocculoso-pruinate_, at length denuded with rain, repand, margin at first involute then expanded, undulato-lobed when luxuriant. =Stem= sometimes 2–3 in., sometimes 3–4 lines long (even obliterated), _stuffed then hollow_, always _thin_, unequal, curved, curved or flexuous, tough and flexile, whitish, everywhere pruinato-villous, rooting and somewhat tomentose at the base. =Gills= _adnate_, very _crowded_ and narrow, unequal, divergent in the lobes, shining white. _Fries._ Exceedingly variable, wholly inconstant in form; substance thin and pliant; commonly densely cespitose, but also single. Odor strong of new meal. On wood, beech, etc. _Stevenson._ Parasitic on a rotten plant of Polyporus annosus on elm. _W.G.S._ White and grayish-white, margin faintly striate; white-spotted, odor distinctly farinaceous. _C.M._ =Spores= 3–4µ long, _Morgan_, _Cooke_, _W.G.S._; 4–5µ _K._ Var. _abscon´dens_ Pk.—obscure. New York, _Peck_, Rep. 31, 39. On trunks, scattered, sometimes loosely clustered. Griffins, Delaware county, N.Y. September. New York, _Peck_, Rep. 31, 39. Kingsessing, near Philadelphia; Mt. Gretna, Pa. _McIlvaine._ 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._ California, _H. and M._
