embraces the base of the perithecia, but we cannot say whether this is 

 accidental. 



Parasitic on old Diatrype stigma, Florida (Calkins). 



This seems to be a distinct species, but, unfortunately, the speci- 

 mens are very meager. 



L. meridionkle, E. & E. Joum. Mycol. IV, p. 76. 



Perithecia scattered, minute (J-^ mm.), compressed, buried in the 

 wood, the projecting, flattened, black ostiolum alone being visible. 

 Asci clavate-cylindrical, 75-90 x 8-9 /i, with abundant parapliyses. 

 Sporidia biseriate, fusoid, hyaline, slightly curved, uniseptatc and 

 slightly constricted, 30-35 x4^5 ji, appendiculate at each end. 



On rotten wood, Louisiana. 



This differs from L. angustilabrwn, B. & Br. in its smaller, 

 buried perithecia. In the specimens of L. angustilabrum, issued by 

 Vize, the perithecia are |-| mm. diam., and nearly superficial. In the 

 original description in Joum. Mycol., the appendages on the sporidia 

 were overlooked. They are conical, hyaline and about 3 fi long.

 ate, oblong-fusiform, slightly curved, 5-7-septate, often slightly con-
