Perithecia scattered or gregarious, at first buried, finally free 

 and superficial, hemispherical, generally surrounded by several con- 

 centric furrows, about 400 /i diam. with a papilliform, black, shining, 

 perforated ostiolum. Asci cylindrical, 8-spored, 100-120 x 5|-7 ji. 

 Sporidia uniseriate or partly biseriate, fusiform, straight or slightly 

 lurved, subinequilateral, 3-septate and slightly constricted at the septa, 

 vellow-brown, 20-30 x 4^ /i. Paraphysos filiform, bi-anching.

Perithecia conoid, flattened at the base, somewhat collapsed when 

 dry, black, seated beneath the epidermis, which is at length thrown 

 off. Asci cylindrical, sessile, paraphysate, 75-80 x 6-8 fi. Spoiidia 

 overlapping-uniseriate, broad-fusoid, subinequilateral, 3-septate and

It is doubtful whether this should be separated from L. Dolioluiu.

 Heptameria viridellaj Cke. Syn. 4714. 



Perithecia small, gregarious, seated on a greenish spot, covei'ed 

 by the epidermis which is ruptured by the minute ostiola. Asci cyliu- 

 drical. Sporidia oblong-fusiform, sometimes curved, 3-septate, green- 

 ish, 25 IX long, the third cell from the base swollen. 



On dead stems of melilot, Bethlehem,'N. Y. 



The marked feature of the species is the greenish color of the spot 

 and of the sporidia. The latter resemble those of L. subconica, ex- 

 except in color.

Perithecia globose, black, shining, papillate, at first covered by 

 the epidermis, at length bare. Asci cylindrical, 75 x 7 fji, paraphysate.
