Mycologia 



granules and paler coloring are called L. amianthina or L. gran- 

 ulosa amianthina. There is little doubt that Scopoli in 1772 

 knew both these forms. Another character in which this spe- 

 cies is both aberrant and variable is the attachment of the gills, 

 which are sometimes squarely adnate or even a little decurrent 

 and at other times they are adnexed or barely reach the stipe. 

 All these variations in granular covering and gill attachment are 

 represented on the Pacific coast, where the plant is common. 

 When the species is more thoroughly known in its entire range, 

 it may be possible to recognize two or three of these forms as 

 species, and it may also be more consistent to group them under 

 a distinct genus between Lepiota and Armillaria, as suggested 

 by Fayod in 1889.

20. Lepiota aspera (Pers.) Quel. Ench. Fung. 5. 1886 



This rather rare but widely distributed temperate species was 

 found only once. L. asperiila Atk. and L. eriophora Peck, de- 

 scribed from American material, should be compared with it 

 carefully.

21. Lepiota nardosmioides sp. nov. 



Pileus thick, fleshy, convex, slow to expand, 6 cm. broad in 

 its unexpanded form, resembling that of Armillaria nardosmia in 

 form and color; surface dry, fibrillose, castaneous, becoming 

 somewhat mottled with lighter and darker areas, margin strongly 

 incurved; lamellae free, crowded, broad, ventricose, pallid; 

 spores ovoid to ellipsoid, smooth, hyaline with an umbrinous 

 tint, 5-7 X 3-5-4 stipe short, 2.5 cm. thick, bulbous, white, 

 glabrous above and cottony below the large, membranous, simple, 

 white, persistent annulus, which is fixed above the center of the 

 stipe and is decidedly cottony on its lower surface. 



Type collected on humus in a redwood forest at La Honda, 

 California, November 25, 191 1, W. A. Murrill & L. R. Abrams
