As to the nature of the large bodies present in the perithecia, 

 which are truly spore-like, it is difficult to determine. Mr. Ellis 

 was of the opinion that they represent mature ascospores while 

 the smaller spores present in the ascus are immature. This seems 

 doubtful to us since the large bodies could not be found within 

 an ascus. 



The species very closely resembles Nectria Peziza (Tode) 

 Fries, both in perithecial and spore characters, but is distinguished 

 by its parasitic habitat as well as by the presence of the large 

 spore-like bodies which accompany the asci within the perithecia.

 Nectria bicolor Ellis & Everh. Proc. Acad. Nat. Sci. Phil. 1893 : 



443. 1893. Not Nectria bicolor Berk. & Br. 



Perithecia thickly gregarious, large, 250-300 mic. in diameter, 

 subglobose with a papilliform ostiolum, clothed, except a space 

 around the ostiolum, with obtuse, septate, clavate hairs which are 

 hyaline near the base but golden-sulphur-yellow near the apices ; 

 asci clavate, 35-40X7-8 mic, 8-spored; spores 2-seriate, 

 crowded, fusoid, i-septate, hyaline, 8-12 X 2 -5~3 m ic. (pi. 5. 



On dead twigs of Carya. 



Type locality: Wilmington, Delaware. 



Distribution: Known only from type locality. 



Specimens examined: Delaware, Commons (type). 



Distinguished by the large, golden-yellow-ciliate perithecia. 



" The yellow color of the hairy coat is the same as in Nectria 

 sulphur ea Ellis & Calk., but there is no subiculum, and in that 

 species the perithecia are not hairy but simply pruinose. 

 Fusarium episphaericum Cooke & Ellis* appears to be the coni- 

 dial stage." 



The hairs in this species are well developed and prominent. 

 The name suggested by Ellis & Everh. is a homonym.f
