Pileus smooth, moist or viscid; not hygrophanous. LEPTONI´DEI (inclining to Leptonia). Pileus flocculose or squamulose; absolutely dry. NOLANI´DEI (inclining to Nolanea). Page 252. Pileus thin, hygrophanous, somewhat silky when dry. I.—GENUI´NI. =E. gran´de= Pk.—=Pileus= fleshy, thin toward the margin, glabrous, nearly plane when mature, commonly broadly umbonate and rugosely wrinkled about the umbo, moist in wet weather, dingy yellowish-white verging to brownish or grayish-brown. =Flesh= white, odor and flavor farinaceous. =Lamellæ= broad, subdistant, slightly adnexed, becoming free or nearly so, often wavy or uneven on the edge, whitish becoming flesh-colored with maturity. =Stem= equal or nearly so, solid, somewhat fibrous externally, mealy at the top, white. =Spores= angular, 3–10µ. =Pileus= 4–6 in. broad. =Stem= 4–6 in. long, 8–12 lines thick. Thin mixed woods. Menands. August. The flavor of this mushroom is not at first disagreeable, but an unpleasant burning sensation is left in the mouth for a considerable time after tasting. It is therefore to be regarded with suspicion. _Peck_, 50th Rep. N.Y. State Bot. SUSPICIOUS. I have not seen this species. It is given that it may be guarded against until tested for edibility. (Plate LXII.) [Illustration: ENTOLOMA SINUATUM. About one-fourth natural size. ] =E. sinua´tum= Fr.—waved. =Pileus= 6 in. broad, _becoming yellow-white_, very fleshy, _convex then expanded_, at first gibbous, at length depressed, repand and sinuate at the margin. =Stem= 3–6 in. long, 1 in. thick, _solid_, firm, stout, equal, compact, _at first fibrillose_, then smooth, naked, shining white. =Gills= _emarginate_, slightly adnexed, ½-¾ in. broad, crowded, distinct, pale yellowish-red. _Fries._ Gregarious, compact, handsome. Odor _strong, pleasant, almost like that of burnt sugar_, not of new meal. The pileus becomes broken into squamules when dry. There is a variety with a shorter stem. In mixed woods. Uncommon. July to October. The gills are often irregular in their attachment. Very poisonous; producing headache, swimming of the brain, stomach pains, vomiting, etc. Worthington Smith, who first experimented with it, ate about ¼ oz., which very nearly proved fatal. _Stevenson._ =Spores= 9µ _W.G.S._ Rhode Island, _Olney_ (Curtis Am. Jour.); Massachusetts, _Sprague_; Connecticut, _Wright_; Minnesota, _Johnson_; New York, _Peck_, Rep. 35. “This and E. fertilis, which are closely allied, are deserving of more than suspicion, for they are veritably dangerous.” _Cooke._ “Wholesome and very good to eat.” _Cordier._ In the presence of such opposite opinions it is better to choose the safer. Do not eat it.
