from this. The diagnosis here given is from a reexamination of the 

 original specc., and differs in some respects from that in Torr. Bull. 



Eu. Platani, (Schw.) 



SphcBria Platani, Schw. Syn. N. Am. 1372 

 Eutypella Platani, Sacc. Syll. 592. 



Pustules gregarious, small, numerous, lying under the epidermis 

 which is slightly raised, and radiately fissured around the erumpent 

 fascicle of short-cylindrical or conic-cylindrical, strongly quadrisulcate, 

 slightly exserted ostiola. Perithecia few in a pustule (4-6 mostly), not 

 deeply buried, small, necks short. Sporidia allantoid, nearly hyaline, 

 10-12 x 2 }i. The asci in the specc, examined had disappeared. The 

 ostiola are at first joined in a brown disk which is soon obliterated. 

 Stroma of a lighter color than the surrounding bark, and without any 

 circumscribing line. 



On loose bark of Platamis, New York, Pennsylvania and Louis- 

 iana. 



Eu. Leaiana, (Berk.) 



Spharia Leaiana, Berk. Hook. L,ond. journ. Bot. IV, p. 311. 

 Eutypella Leaiana, Sacc. Syll. 585. 



Innate. Stroma pallid, about \ a line diani., of a rather loose 

 texture, and circumscribed by a black line penetrating the wood, 

 Perithecia not numerous, circinate, elliptical. Ostiola forming a little 

 tuft, rather elongated, umbilicate, finely grooved, granulated. Asci 

 lanceolate. Sporidia minute (7-8 p long), curved like those of Dia- 

 trypella verruciformis. Distinguished from Diaporthe Carpini 1 

 by its pretty, granulated ostiola and its minute, curved, not lanceolate 

 sporidia. 



On bark of dead hornbeam (Carjyinus), Ohio and Carolina. 



En. <mi6stoma, (Schw.) 



Sphceria goniostoma, Schw. Syn. N. Am. 1373. 

 Valsa goniostoma, Cke. Valsei of U. S. No. 9. 

 Eutypella goniostoma, Sacc. Syll. 587. 



Pustules closely covered by the epidermis, flat and thin, often con- 

 fluent 1|-2| mm. diam. Perithecia 8-15 in a pustule, J-J mm. diam., 

 crowded, subcircinate, buried in the bark, without any stroma, Ostiola 

 stout, crowded, erect, deeply quadrisulcate, short conic-cylindrical, 

 erumpent in an orbicular or elliptical tuft closely embraced by the 

 perforated epidermis. Asci about 25-30 x 5 // (p. sp.). Sporidia sub- 

 biseriate, allantoid, yellowish, not strongly curved, 7-9 x 2 fjt. 



On various branches, Carolina (Curtis), on the younger branches
