=E. prunulo´ides= Fr.—_prunus_, a plum. =Pileus= 2 in. and more broad, whitish, becoming yellow or livid, fleshy, _bell-shaped then convex_, at length flattened, somewhat umbonate, unequal (but not repand), even, _viscid_, smooth, at length longitudinally cracked, at length slightly striate at margin. =Stem= 3 in. long, 3–4 lines thick, fibrous-fleshy, solid, equal, even or slightly striate, smooth, naked, white. =Gills= somewhat free, emarginate, rarely rounded, at first only slightly adnexed, 3–4 lines broad, crowded, ventricose, white then flesh-color. _Fries._ _Odor strong of new meal_, wholly that of A. prunulus. Very scattered in growth. Like A. lividus, but very different, thrice as small. It differs entirely from A. cervinus. On the ground in woods. Autumn. =Spores= subglobose, coarsely warted, 10µ _Massee_; regularly six-angled or one angle more marked, 8µ _B._; 9µ _W.P._ North Carolina, dry swamps, _Curtis_; Minnesota, _Johnson_. POISONOUS. _Roze._ I have not seen this species. Do not eat it before carefully testing. III.—NOLANI´DEI. _Pileus thin, hygrophanous, repand, etc._ =E. clypea´tum= _Linn._—resembling a shield. =Pileus= as much as 3 in. broad, _lurid_ when moist, when dry gray and _variegated or streaked with darker spots or lines_, fleshy, _bell-shaped then flattened_, umbonate, smooth, fragile. =Flesh= thin, white when dry. =Stem= almost 3 in. long, 3–4 lines and more thick, stuffed, at length hollow, _wholly fibrous_, equal, round, fragile, _longitudinally fibrillose_, becoming ash-colored, pulverulent at the very apex. =Gills= _rounded-adnexed_, separating-free, 3–4 lines broad, ventricose, somewhat distant, dingy, then red-pulverulent with the spores, serrulated at the edge chiefly behind. It has occurred in May cespitose; better developed and solitary in the end of August. In woods, gardens and waste places. Frequent. Spring, autumn. _Stevenson._ North Carolina, _Schweinitz_, _Curtis_; Ohio, _Morgan_; New England, _Frost_; California, _H. and M._; Rhode Island, _Bennett_; New York, _Peck_, Rep. 23. POISONOUS. _Leuba._ I have not seen this species. It should not be eaten before careful testing. =E. rhodopo´lium= Fr. _Gr_—rose; _Gr_—gray. =Pileus= 2–5 in. broad, hygrophanous, when moist dingy-brown (young) or livid, becoming pale (when full grown), _when dry isabelline-livid, silky-shining_, slightly-fleshy, bell-shaped when young, then expanded and somewhat umbonate or gibbous, at length rather plane and sometimes depressed, _fibrillose_ when young, _smooth when full grown_, margin at the first bent inwards and when larger undulated. =Flesh= white. =Stem= 2–4 in. long, 3–5 lines thick, _hollow_, equal when smaller, when larger attenuated upwards and _white-pruinate at the apex_, otherwise _smooth_, slightly striate, _white_. =Gills= adnate then separating, somewhat sinuate, slightly distant, 2–4 lines broad, _white then rose-color_. _Fries._
