Mycologia 



Type collected by F. S. Earle (43) on September 4, 1908. The 

 species suggests Anellaria fimiputris and the spores resemble those 

 of Anellaria and Campanularius in form but are lighter in color, 

 staining the lamellae purplish-brown rather than black.

 Folk 32 : 489. 1879 



Agaricus melaspermus Fries, Epicr. Myc.,219. 1838. 



Pileus fleshy, soft, convex to plane, obtuse, 3.5-4.5 cm. broad; 

 surface smooth, glabrous, slightly viscid, often areolate, white, 

 straw-colored on the disk; lamellae slightly adnexed, crowded, 

 ventricose, pallid to cinereous, then violet-black ; spores ovoid, fus- 

 cous, 10 x 6fx; stipe equal, glabrous, hollow, white, 4-6 cm. long, 

 6-7 mm. thick ; annulus membranous, white. 



Type locality : Europe. 



Habitat : On manure or manured ground in the open or par- 

 tially shaded. 



Distribution : New England, New York, Texas, Costa Rica, 

 etc. ; also in Europe.

Specimens so named are at Albany, collected by Burnham on 

 lawns in Albany in August, 1905. Similar plants were found by 

 me at Lake Placid, growing scattered under a white pine tree in 

 the open, and I described them as follows : " Pileus semiglobose, 

 5 cm. broad; surface smooth, glabrous, dry when found, pure- 

 white, becoming slightly yellow in spots on drying ; context white, 

 firm, eaten by snails ; lamellae sinuate-adnate, crowded, plane, 3-4 

 times inserted, pure-white at first, notched on the edges ; stipe equal, 

 dry, apparently solid, fibrillose-scaly, finely frosted above the tiny; 

 apical ring-trace, 7 cm. long, 7 mm. thick; veil slight, white, eva- 

 nescent." 



Specimens from Bresadola resemble 5". bilamellata in general 

 shape and have dark-colored lamellae with spores that, are broadly 

 ellipsoid, smooth, umbrinous under the microscope, reminding one 

 of Panaeolus in shape, slightly apiculate, about 10-12 x 7-8^.
