56 Ellis and Everhart : New Species of Fungi 



Hypoxylon : sporules oblong brown, becoming uniseptate ; 12 

 16x4-5.5// on slender basidia about 20x2 pu 



Varies from the usual type of Diplodia. 



Ascochyta mali E. & E. 



On living limbs of Pints Mains, at the Agricultural College, 



Mich., May, 1899 (C. F. Wheeler). 



Spots circular, 0.5—1 cm. in diameter concave, of a pale brick-red 

 color, with the margin narrowly free, sometimes becoming much 

 larger, extending for 2 cm. and nearly surrounding the limb. 

 These spots appear to be formed from the altered substance of the 

 bark which is changed in color and cracks away around the mar- 

 gin from the surrounding bark which remains in its normal condi- 

 dition : perithecia at first solitary, a single one erumpent in the 

 center of the circular disk, finally 2-4 or more scattered on the 

 same disk : sporules oblong or oblong-elliptical, smoky-hyaline, 

 uniseptate, 6-8x2.5-3.5/^. .On the same spots also occurs a 

 Phoma (P. ambigua Sacc.)? with sporules much resembling those 

 of the Ascochyta only without any septum, and a Phlyctaena {P. 

 Mali E. & E.) with filiform sporules curved near one end, 20-27 

 X 1.25-1.5 // in numerous smaller perithecia scattered on the spots. 

 The fungus soon kills the limbs. 



Stagonospora desmodii E. & E. 



On dead stems of Desmodium tortuosum, Lake City, Fla., Oct. 

 1899 (H. H. Hume). 



Perithecia scattered or gregarious on reddish-brown discolored, 

 indefinite spots which become darker, subcuticular, 1 50-200 p. in 

 diameter, slightly raising the cuticle which is blackened over 

 them: sporules oblong, hyaline, 3-4-guttulate, 8-12 x 4~5/*. 



On the same stems, on elongated black spots with a white cen- 

 ter is a Cercospora with long, brown, septate hyphae cespitose on a 

 sphaeroid base and slender, hyaline, multinucleate conidia 80- 

 ioox 3-4 fi f becoming multiseptate {Cercospora melalenca E. &E.). 



Camarosporium hederae E. & E. 



On dead shoots of Hedera Helix, Nuttallburg, W. Va., July, 

 1899 (L. W. Nuttall, no. 958). 



Perithecia erumpent-superficial, ovate, attenuated above into a 

 short-conical or short-cylindrical ostiolum, about 200 ft in diameter, 

 thickly scattered or even densely crowded : sporules globose or
