Sphaerioidaceae. 



Sphaeropsis stictoides sp. nov. 



Amphigenous; pycnidia scattered, without spots, buried, 

 black, rather corky, about }4 mm., the papilliform ostiolum 

 erumpent, surrounded by the whitish upturned leaf tissue ; 

 sporophores unusually long, slender, hyaline, about 20 x 2 u. ; 

 sporules irregularly oval or oblong, often inequilateral, ends 

 subacute, continuous, brown, 26-28 x 9-11/^. 



On fallen rotting leaves of Eucalytus sp., Stanford Univer-

 hypophyllous on discolored spots, crowded in circular groups ; 

 peridia low, at first erose, becoming somewhat revolute and 

 coarsely torn; spores globoid, 14-22 ft in diameter, minutely

Cercospora thermopsidis sp. nov. 

 Spots yellowish or pallid, not bordered, irregular, angular 

 bounded by the veins, 3-4 mm. or by confluence much larger 

 involving considerable areas ; conidiophores amphigenous 

 but mostly hypophyllous, densely fascicled, forming subglob- 

 ose masses that are at first scattered and olivaceous but be-
