82 ERYTHEA. 



Perithecia caespitose-erumpent, depressed-globose, | mm. 

 diam. with a papilliform ostiolum. Sporules oblong, obtuse, 

 20-25x10-12// brown. This is a well marked bat rare species. 



Diplodia inquinans. On fallen limbs of Negundo acer- 

 oides. Phillips Co., Kan., March 23, 1896 (No. 2072). 



Perithecia scattered or 2-3 together, not confluent, buried 

 in the bark which is slightly raised and perforated by the 

 papilliform ostiolum, ^— | mm. diam. Sporules oblong-ellip- 

 tical, brown, uniseptate, scarcely constricted, 12-15x3-4//, 

 abundantly discharged and blackening the surface of the 

 bark as in Melanconium. 



Differs in this respect and in its smaller sporules from the 

 other species on Celtis. 



Cercosporella nivea. On living leaves of Solidago rad- 

 ula. Rooks Co., Kan., Sept. 23, 1895 (1951). 



Scattered over both sides of the leaves without any spots, 

 forming small, nearly snow-white patches. Fertile hyphae 

 caespitose, continuous, hyaline, oblong-cylindrical, suben- 

 tire, sometimes swollen at the tips, 15-25x4/*. Conidia long, 

 slender, multi-nucleate, hyaline, 100-160x3-4//. 



Outwardly resembles C. cana, Sacc, but the hyphae are 

 very different and the conidia much longer and narrower. 



Coniosporiiim Maydis. On old corn stalks. Eooks Co., 

 Kan., July 24, 1895 (No. 1789). 



Conidia globose or subglobose, brown, 3^5^// diam. seated 

 on an orbicular, flattish-tubercular stroma ^1 mm. diam. 

 and with the black stratum of conidia resembling a black 

 Patellaria. 



Differs from C. inquinans, D. & M. (as represented in F. 

 Gallic! 4697) in its darker color, rather larger conidia and 

 the presence of the gray tubercular stroma. The tufts in our 

 specimen show indications of becoming confluent in which 

 case it would closely resemble C. iiiquinans. 



Dendryphium curtipes. On the underside of an old hog 

 trough. Eooks Co., Kan., Dec. 20, 1894 (No. 1612).
