Naucoria suborbicularis (Bull.) Fr. from which it is 

 separated by its farinaceous odor and taste, its fragile character, 

 lacunose or pitted pileus and its stem striated at the top. 



Oidium asteris-punicei n. sp. 



Amphigenous indeterminate, widely and thinly effused, whitish ; 

 fertile hyphae suberect, hyaline, septate, simple; spores terminal 

 catenulate, ellipsoid or oblong, rounded or subtruncate at the ends, 

 hyaline, 30-60 p, long, 1 5-20 ,j^ broad. 



Living or languishing leaves of red stemmed aster, Aster 

 puniceus L. Letchworth Park, Wyoming co. September. 



Related to Oidium erysiphoides Fr., but I find no rosy 

 tinted tufts and the hyphae are nearly as broad as the spores. Per- 

 haps it is the conidial stage of Erysiphe cichoracearum 

 DC.
