common orifice and form heaps of spores resembling perithecia. The 

 Newfield specc. are younger and not as well matured but show the 

 same general characters as the California specc. 



Sphaewpsls Alni C. & E. in Krieger's Saxon Fungi No. 847, is a 

 true Sphaeropsis and different from this. 



Ovularia lotophaga E. & E. 



Ou living leaves of Lotus Torreyi. Sissou, Cala. , July 1894; 

 W. C. Blasdale, No. 288. 



Spots irregular or suborbicular, 2-3 mm. diam., grayish-brown, 

 with a narrow, darker border. Hyphae subfasciculate, hyaline, con- 

 tinuous, simple or sparingly branched 15-25 x 2£-3 /i, subgeniculate 

 above. Conidia subglobose or obovate-globose, 7-9 x 5-7 ;>.. 



Ramularia circumfusa E. & E. 



On leaves of Rumex obtusifolius. Oberlin, Ohio, May, 1894. 

 Prof. F. D. Kelsey, No. 133. ' 



Amphigenous. Spots small, 1-2 mm., whitish, with a brown 

 border, thickly scattered over the leaf. Hyphae often issuing from 

 the stomata of the leaf, very long, 100-150 x 2i-3 //., vaguely and 

 loosely branched, distantly septate, hyaline, assurgent, subgeniculate 

 and toothed above, Conidia varying from ovate or oblong-elliptical, 

 5-10 x 2-2jj fi to cylindrical 10-15 x 2-2-2 ,", hyaline, continuous, 

 concatenate. Whether the conidia ever became septate we can 

 not say. 



Differs from B. pratensis Sacc. in its smaller conidia and longer 

 hyphae, and its effused growth, spreading out around the spots so as 

 to form white, orbicular patches 2-3 mm. diam. 



Ramularia cercosporoid.es E. & E. 



On leaves of Epilobium epicatum. Seattle, Wash. August 1894. 

 Prof. C. V. Piper, No. 290. 



Spots numerous, variable in size from 1-3 mm., often confluent in 

 irregular, subangular patches £-1 cm. diam., dark- purplish, with a 

 dull-whitish center. Hyphae hypophyllous, few in a tuft, arising 

 from a yellow-brown, stromatic base, subgeniculate, continuous or 

 faintly 1-2-septate, brownish-hyaline, nucleate, 30-60 x 3£ ,«. 

 Conidia terminal, oblong-fusoid, hyaline, at first continuous, 

 finally narrowed in the middle and 1, or more, septate, 15- 

 30 x 4-5 ;/-.
