164 PROCEEDINGS OF THE ACADEMY OF [1893. 



Sporules filiform, rather broader above, multinucleate, becoming 3- 

 5-septate, hyaline, 30-55 x l£-2/*. 



Var. destruens (Bartholomew, No. 703, Sept., 1892), has the tips 

 of the leaves and often the entire leaf mottled with black and yellow, 

 becoming brown and dead, and the sporules 40-75 x 2-2 ?//.. 



This differs from 8. ribis Desm. in its septate sporules and the 

 different character of the spots. 



Septoria gaillardiae E. & E. 



On leaves of Gaillardia pulchella, Rockport, Kansas. A.ug., 



1892. (E. Bartholomew.) 



Spot amphigenous, orbicular, light brown, with a dull white center ; 

 both the dull white center and the larger, brown spot in which it is 

 included, are surrounded by a narrow, raised border. Perithecia 

 amphigenous, 75-90//, semierumpent, black, either confined to the 

 white central spot or often scattered over the white and brown. 

 Sporules filiform, nucleate, 45-65 x 1 l-li,'^ 



Septoria glabra E. & E. 



On leaves of uEsculus glabra, Indianapolis, Indiana. Aug., 1880. 

 (Coll., W. J. Beale, com., G. H. Hicks.) 



Perithecia hypophyllous, globose, black, 75-85// diarn., scattered 

 on dark brown spots which are more or less whitened, especially 

 above, by the thin bleached epidermis. The spots are situated 

 either in the green parts of the leaf or on dead red-brown areas, and 

 are rather irregular in outline, 2-3 mm. diam., with a rather broad, 

 not raised, dark border, the central portion more or less whitened. 

 Sporules filiform, continuous, nearly straight, faintly nucleate, 30- 

 45xH-2,u. 



This is certainly different from 8. wscidi (Lib.) which (sec. 

 specc. in Sacc. M. Ven., Thum. M. U. and Briosi and Cavarra's 

 F. Parass.) has only 1-3 perithecia on small (1-1 \ mm.), white 

 spots, with shorter, thicker sporules arcuate curved and about 

 3-septate. 



Briosi and Cavarra remark that Septoria aiscidina Tlriim. and S. 

 hippocastani B. & Br., are hardly more than forms of 8. cesculi and 

 the species in our Exsiccati seem to warrant that conclusion. 



Septoria lepachidis E. & E. 



On leaves of Lepachys columnaris, Rockport, Kansas. June, 



1893. (Mr. E. Bartholomew, No. 584.)
