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. Trunks of trees. Lyndonville. _C.E. Fairman._ _Peck_, 44th Rep. N.Y. State Bot. West Virginia, on oak trunks. _McIlvaine._ High, agreeable flavor; texture about as in P. ostreatus. *** _Gills decurrent; stem distinct, etc._ (Plate XXXVI.) [Illustration: SECTION OF PLEUROTUS SAPIDUS. One-half natural size. ] =P. sa´pidus= Kalchb.—savory. Cespitose, or several pilei appearing to spring from a common branched stem. =Pileus= 1–3 in. across. =Flesh= thick, excentric, regular, convex or obtusely gibbous then depressed, glabrous, white or brownish. =Stem= stout, solid, several usually springing from a thickened knob, whitish, 1–2 in. long, expanding upward into the pileus. =Gills= decurrent, rather distant, narrow, whitish. =Spores= elliptical, 10–11×4–5µ. On elm trunks. A very variable species; according to Kalchbrenner, the spores have a faint tinge of lilac, and the pileus is white, tawny, brownish, or umber on the same trunk. The white form only has been met with in this country. _Massee._ =Spores= with a lilac tinge, oblong or a little curved and pointed, 8.3×3.7µ _Morgan_; oblong, 9–11.5×4–5µ _Peck_; 10–11×4–5µ _Massee_. Not observed in England until 1887. Quite common throughout the United States, growing upon decaying wood, whether above or under ground. It has few distinct features. The only positive one distinguishing it from P. ostreatus is its lilac-tinted spores. The tint is faint but noticeable upon white background. Excepting for purposes of the student, its separation, as a species, from P. ostreatus is not necessary. When old it has more body than the latter, but is equally superior as a food fungus. Professor Peck remarks of it: “A stew made of it is a very good substitute for an oyster stew.” It can be cultivated by watering the places upon which it is known to appear. =P. pome´ti= Fr.—_pometum_, an orchard. =Pileus= white, fleshy, soft, sub-flaccid, irregular, involute, convex, even, smooth, disk depressed. =Gills= decurrent, crowded, separate behind. =Stem= 2–3 in. high, 3–4 lines thick, excentric, solid, tough, ascending, rooting. On trunks of pear and apple trees. Especially distinguished by the rooting stem. North Carolina, edible, _Curtis_; California, _H. and M._
