 l-'.ntypella J'lntani, Sacc. Syll. 592. 



Pustules gregarious, small, numerous, lying under the epidermic 

 which is slightly raised, and radiately fissured around the orumpent 

 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 allautoid, nearly hyaline, 

 10-12 x2 u. 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 1 bark, and without anv

circumscribing line.

 F.ntypella Leaiana, Sacc. Syll. 



Innate. Stroma pallid, about \ a line diam.. of a rather loos- 

 texture, and circumscribed by a black line penetrating the wood 

 Perithecia not numerous, circinate, elliptical. ( )stiola forming a little 

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

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

 trypvUu verrucceformis. Distinguished from Diaporthe Carpini 

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



sporidia. 



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

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

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

 crowded, siibchrinate, buried in the bark, without any stroma. Ostiola 

 .-tout, crowded, erect, deeply quadrisuleate, short conic-cylindrical, 



erumpent in an orbicular or elliptical tuft closely embraced by the 

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

 biseriate. allantoid. yellowish, nor strongly curved. 7-9 x '2 IJL.
