NEW SPECIES OF KANSAS FUNGII. — II. 49 



ruptured at the apex. Sporules elliptical, or broadly elliptical, 

 brown, 16-24x7-10/^-. 



S. sociata Lev. on the same host has the perithecia cespitose. 



Spheeropsis Populi. On dead branches of Populus monilifera, 

 July 17, 1896 (No. 2191). 



Gregarious, perithecia buried in the bark, 200-260/^ diam., rais- 

 ing the bark into flattish pustules which are barely pierced by the 

 minute osteola, but not ruptured. Sporules oblong, obtuse, 15-22x 



7-9,a. 



Sphasropsis ulmea. On dead shoots of Ulmus Americana 

 Feb. 20, 1897 (No. 2364). 



Perithecia abundant and evenly scattered, minute, 200-300/^ in 

 diam., subcuticular, raising the epidermis into minute pustules but 

 for the most part not rupturing it. Sporules oblong-elliptical, brown, 

 15-21x8-10,a. 



S. uhnicola E. & E., has the perithecia exactly like this but in 

 that the sporules are 20-30x1 2-1 5,a. S. ulvii, Sace. & Eoum., has 

 sporules 60-70x14//, and/S. ulmi, Karst., has them 10x4/^. 



Diplodia celtidigena. On fallen limbs of Celtis occidentalis. 



In Erythea, IV, No. 5, p. 82, this was erroneously named D. 

 inquinans, and the host given as Negundo aceroides by an oversight. 

 Differs from D. Celtidis Roum. and D. argentina Speg., in its much 

 smaller sporules. 



Diplodia rhizogena. On exposed roots of Fraxinus viridis, 

 March 27, 1896 (No. 2086). 



Perithecia globose, ^ mm. diam., suberumpent, in short series, 

 2-3 mm. long, through longitudinal cracks in the bark. Sporules 

 oblong or oblong-elliptical, deep-brown, scarcely constricted, 20- 

 22x8-1 0/^ 



Differs from D. inquinans West, in its seriate less distinctly erum- 

 pent perithecia and rather smaller spores. Resembles D. seriata 

 De Not, in the seriate perithecia, but that species has the sporules 

 17-18x7-9//, and is on a different host. 



Diplodia Ceanothi. On dead Ceanothus ovatus, April 22, 1896 

 (No. 2130). 



Perithecia scattered, covered, small, 200// diam., raising and 

 slightly rupturing the epidermis. Sporules oblong-elliptical, con- 

 stricted, obtuse, deep-brown, 15x7-8//.
