Genus Lepiota 331 



hard, covered at first up to the annulus by the thick, fioccosc- 

 fibrillose cinnamon-brown universal veil, which is then broken 

 into thick, wedge-shaped scaly masses, which often disappear 

 in part; annulus at first manifest, recurved, thick, plicatc- 

 striate from the gill-pressure, becoming evanescent; odor and 

 taste none or shght; spores long, fusiform, acuminate-pointed 

 at both ends, 18-25(30) X 5-6(7) yu, smooth, hyaline; cystidia 

 none; basidia clavate, 4-spored, 55-60 x 10-12 fx; sterile cells 

 on edge of gills indistinct, saccate. 



On very decayed wood or debris. Type collected by Prof. 

 F. C. Stewart at Seventh Lake, Adirondack Mts., New York, 

 September 1, 1921. Also in the Medicine Bow Mts., near Cen- 

 tennial, Wyoming, September 5, 1923. Collected by C. H. 

 KaufTman. 



This is apparently a rare species, or perhaps usually con- 

 fused with related ones. The spores are surprisingly large, and 

 are unique; one end is often drawn out to a needle-like pro- 

 longation. It probably occurs in mountainous regions through- 

 out the northern part of our country. 



Lepiota flammeatincta, sp. nov. 



Pileus fleshy, 2-3 cm. broad, campanulate-expanded, at 

 length ahnost plane, obtuse or obsoletely umbonate, dry or 

 nearly so, cuticle at first continuous and "tawny" (Ridg.) or 

 disk chestnut color, soon breaking up into numerous, small, ap- 

 pressed, fibrillose, tawny scales, sometimes subexcoriate, mar- 

 gin not striate, cuticle changing quickly to "flame-scarlet" 

 when plant is picked or touched; flesh thin, about 1.5 mm., 

 submembranous on margin, white, unchanging, except adjacent 

 to cuticle; gills free, subremote, narrow, crowded, white, un- 

 changing; stem 6-8(10) cm. long, 2.5-5 mm. thick, tapering 

 gently upwards, peronate at first by a somewhat tawny, fibrillose, 

 often reticulate sheath, up to the annulus, fibrillose covering 

 changing quickly to "flame-scarlet" (Ridg.) when handled, 

 whitish within, dehcately stuffed by white fibrils then hollow, 

 apex white and naked and unchanging; annulus membranous,
