 slightly bitterish ; spores 8-9 X 4-4 . 5 ix, subellipsoid-oblong,

Whether this is L. suhfelina Murrill can not be definitely 

 known. After picking, the plants were laid exposed on a table, 

 when the flame-scarlet tints disappeared and the tawny colors be- 

 came again noticeable. The flesh and gills do not possess the

 (i.e., the universal veil) of the cap and stem seem to possess 

 this property. 



Lepiota cuneatospora, sp. no v. 



Pileus 1.5-3 cm. broad, dry, at first obtusely oval, even and 

 uniformly flesh-pink, at length campanulate-expanded, broadly 

 mammillate, umbo pinkish, elsewhere paler to dull cream color, 

 the cuticle glabrous, even or becoming rimulose, sometimes ex- 

 coriate on margin; flesh white, thin, thickened at umbo, un- 

 changing; gills free, approximate, somewhat truncate-rounded 

 behind, rather narrow or of medium width, crowded, thin, 

 whitish; stem 4-5(6) cm. long, 2-4 mm. thick, equal, glabrous 

 above and below the annulus, even, hollow, silky-shining, white, 

 flesh-tinted or white within; annulus membranous, erect-flaring, 

 superior or at least above middle of stem, distinct and often 

 with thick edge, white or tinged pink on lower side, fixed or 

 submobile; odor and taste slight or none; spores 7-9 X 3 ^t, 

 narrowly wedge-shaped, subtruncate at broad end, with scat- 

 tered, obscure papillae, hyaline; cystidia none; sterile cells on 

 edge of gills obscure; basidia clavate, about 28 X 6 ju. Grega- 

 rious, or forming loose arcs like parts of fairy rings; on grassy 

 ground in a grove of pine. Takoma Park, Maryland. July 22, 

 1919. Collected by C. H. Kauffman. 



The annulus at the time of its formation is continuous below 

 with a very thin evanescent outer layer on the stem. The non-
