REPORT OF THE STATE BOTANIST igiO 35 



Naucoria sub orbicularis (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 /y. long, 15-20 ^ 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. 



Amphigenum, indeterminatum, late et tenuiter effusum, albidum; 

 hyphae fertiles suberectae, hyaHnae, septatae, simplices; sporae 

 catenulatae, acrogenae, ellipsoideae oblongaeve, utrinque obtusae 

 subtruncataeve, hyalinae, 30-60 x 15-20/x. 



Oxybaphus floribundus Chois. 

 Waste places. Albany. September. S. H. Burnham. Intro- 

 duced from the West but apparently well established.

 this mushroom is said to emit an odor similar to that of mice. 



Phoma piceina n. sp. 



Perithecia few, scattered, prominent "but minute, black; spores 

 ellipsoid or oblong, hyaline, 8-12/-/- long, 4-5 y-y, broad.

 D. B. Young. 



In these specimens the leaves have been injured by some insect 

 which has caused a swelling at the base and may have been the 

 primary cause of the death of the leaves.
