Seems to differ from Eu. Platani, Schw., in its shorter sporidia 

 and convex pustules. 



Eu. constellata, (B. & .) 



Valsa {Eutypella) constellata, B. & C. Grev. XIV, p. 46. 



"Pustules orbicular, seriate or irregularly scattered, erunipe 

 densely gregarious. Perithecia black, globose, few (4-6), crowded, 

 necks abbreviated, ostiola sulcate. Asci clavate, 8-spored. Sporidia 

 allantoid, hyaline. 



On branches of Carya, &c, North Carolina.' 7 



Eu. radula, (Pers.) 



Sphceria radula, Pers. Syn. p. 37, sec. Schw. Syn. N. Am. 1369. 

 Valsa radula, Pers. in Cke. Valsei U. S. No. 15. 

 Eutypella grandis, (Nits)? Sacc. Syll. 578. 



Commonly in extensive tracts confluent far and wide under the 

 closely enveloping epidermis which is roughened by the projecting 

 tufts of ostiola more or less prominent and mostly 5-sided. Perithecia 

 rather large, lying in a white stroma formed from the substance of the 

 bark, without any conceptacle or circumscribing line. 



On various branches, especially of poplar, Carolina (Schw.). 



Sec. Cke. (1. c), the sporidia are 10-12 fi long. This measu 

 ment, however, was from European specc. 



Eu. niphoclina, (Cke.) 



Valsa niphoclina, Cke. Grev. XI, p. 109. 

 Kxsicc. Rav. F. Am. 748. 



Lineate-erumpent. Perithecia ovate, lying in a white stroma. 

 Ostiola short, converging, sulcate, erumpent in transverse lines. Asci 

 cylindric-clavate. Sporidia allantoid, hyaline, 8x2//. 



On bark of Betula nigra, Florence, So. Ca. (Ravenel). 



The spec, in our copy of Rav. F. Am. is worthless not even 

 affording perithecia. 



Eu. conseptata, (Schw.) 



Sphczria conseptata, Schw. Syn. N. Am. 1374. 



Valsa conseptata, Stev. Add. to Cooke's Valsei, No. 114. 



. Not pustulate, gregariously erumpent, effused under the epider- 

 mis, disk at first brownish-black, convex, at length obliterated by the 

 slightly exserted, stellate-angular ostiola. Perithecia nestling in the 

 bark, variously subcircinate, without any distinct conceptacle, but 

 several clusters surrounded by one common circumscribing line pene- 

 trating the bark and wood. Sec. Stevenson, 1. c. sporidia allantoid, 

 hyaline, 8 J x3J /a. 



Found under the bark of Gleditschla, Bethlehem, Pa. (Schw.).
