conic ostiola dotting the surface of the stroma. Asci cylindrical, spore 

 bearing part 30-35 x3 /*, with a slender, thread-like base about 20 <L 

 long. Paraphyses not observed. Sporidia uniseriate, yellowish-

This and the preceding- species vary from the usual type of Dia> 

 ti'ype, in the shape of their sporidia. 



Species imperfectly known or to be rejected. 

 D. niauipularis, B. & C. in Herb. Curtis. 



This is mentioned in Grev. XIV, p. 16. No description given- 

 as far as we know, 



D. plagia, B. & ('.. Grev. IT, p. 96. 



"Bursting through the bark transversely. Ostiola substellate. 







Stroma brown, scanty. Asci clavate. Sporidia 8 in each ascus, sau- 

 sage-shaped." 



On Liriodendron, South Carolina. 



D. pilulifera, (Fr.) 



Sphczria pilulifera, in Herb. Schw., Syu. N. Am. 1234. 



Sec. Grev. XIII, p. 37, this can hardly be the S. pilulifera 1 

 Fr. 



D. cornicnlata, (Ehr.) 



This is quoted by Schw. cv; Berk, as found in this country, but the 

 species is not well known. The specc. in Rav. Car. IV, No. 43, are 

 Eutypdla heteracantha, Sacc. 



D. collariata, C. & E. Grev. IV, p. 102. 



Our. specc. of this are only Valsa caryigena, B. &. C., with the 

 ostiola abnormally elongated. 



D. bispora, B. & C. Rav. Car. IV, 45. 



This is not an aseigerous fungus, but a species of Didymosporivm
