 Mich. May, 1892. (G. H. Hicks. No. 574). Perithecia scattered 

 or subgregarious, superficial, convex-discoid, perforated at the

 hyphse around the base. Asci obovate, 22-30x12-20//, sessile, 

 8-spored. Sporidia inordinate, clavate-oblong, hyaline, uniseptate 

 and strongly constricted at the septum so as easily to separate into 

 two parts, quite variable in size — in some perithecia 7-10 x 2J/t, in 

 others 10-15 x 3-3 Ifi. 



Asterina leemingii E. & E. 



On living leaves of Galax a/phylla, Marion, Va. June, 1892.

 branched hyphse furnished with globose hyphopodia 8-10//, diam. 

 Perithecia numerous, seated on the hypha?, depressed-globose, 150/*, 

 diam., with a papilliform ostiolum which is soon deciduous leaving 

 the perithecium perforated and convex. Asci oblong, 35-40 x 20-- 

 24//, aparaphysate, 8-spored. Sporidia crowded, oblong-fusoid, 

 yellowish-hyaline, uniseptate, scarcely constricted, slightly curved,

 in the bark, 1J mm. diam., the apex erumpent and surrounded by 

 the lacinise of the ruptured epidermis, ostiolum tubercular-conical,

 6-7//. Sporidia uniseriate, oblong, brown, 15-20 x 7-8//, not append-
