Entoloma tortipes Murrill 

 Twisted-stemmed Entoloma 



Plate 7. Figure 4. X 1 



Pileus convex to subexpanded, with a small, conspicuous, conic 

 umbo, rather thin and fragile, reaching 3 cm. broad ; surface 

 smooth, with a satiny gloss, rosy-isabelline, margin concolorous, 

 entire, sometimes splitting with age ; context very thin, pallid ; 

 lamellae sinuate, of medium breadth, subcrowded, slightly ventri- 

 cose and rounded behind, entire on the edges, pallid to rose-col- 

 ored ; spores ellipsoid, angular, uniguttulate, usually apiculate, 

 rose-colored, 9-1 1 X 5-7^', stipe decidedly tapering upward, con- 

 spicuously twisted, smooth, glabrous, polished, white or pale- 

 avellaneous, solid, 6-7 cm. long, 3-6 mm. thick. 



Known only from a single collection taken from an old decidu- 

 ous stump in the New York Botanical Garden. 



Entoloma inocybiforme Murrill 



Inocybe-like Entoloma 



Plate 7. Figure 5. X 1 



Pileus fleshy, fragile, convex to deeply depressed and irregular 

 with age, distinctly umbonate, loosely clustered, abundant, 4-6 

 cm. broad; surface hygrophanous, glabrous, striate to the small, 

 conic umbo, avellaneous-isabelline, margin concolorous, conspicu- 

 ously striate, upturned and irregular with age ; context very thin, 

 dull-whitish, decidedly farinaceous in taste but without odor; 

 lamellae deeply sinuate, almost free, very broad, ventricose, rather 

 distant, pallid to rose-colored ; spores subglobose to broadly ellip- 

 soid, decidedly angular, apiculate, uniguttulate, rose-colored, 

 8-10 X 7 p ; stipe equal or slightly enlarged at the base, smooth, 

 glabrous, concolorous, solid, 4 cm. long, 5 mm. thick. 



This species was found abundant among weeds in the New 

 York Botanical Garden in 191 5, but has not been reported since. 

 Its shape and color suggest Inocybe, of the rusty-spored series, 

 but the spores are rose-colored.
