L. prominens, Pk. 31st Rep. p. 50. 



Perithecia very prominent, hemispherical, adnate at the base, 

 180-200 [1 broad, smooth, 'black. Ostiola distinct, compressed, black 

 and shining. Asci subclavate. Sporidia biseriate, oblong or sub- 

 fusiform, straight or slightly curved, colored, 5-septate, 20-25 // long. 



On dead twigs of Cephalanthus occidentalis, New York.

 Exsicc. Rehm Ascom. 181, 484, 749.— Sydow M. March. 257, 985. 



Perithecia scattered, immersed, black, minute, (generally on stems 

 from which the epidermis has fallen away), spherical or subelliptical, 

 with a slightly prominent, bare, ellipsoid or linear ostiolum. Asci 

 clavate-cylindrical, p. sp. 70-80x10-12 /jl, 8-spored, with abundant 

 paraphyses. Sporidia biseriate, fusoid-oblong, uniseptate, acute and 

 yellowish, finally 5-7-septate and darker, with the ends more obtuse, 

 20-30 X 5-8 fji (mostly 20-22 x 5-6 fi), straight or slightly curved, and 

 without appendages. 



On dead herbaceous stems, Louisiana and Pennsylvania, probably 

 common throughout. 



Distinguished from L. insidiosum by the absence of appendages 

 on the sporidia, but certainly very closely allied to that species.
