 accidental. 



Parasitic on old Diatrype stigma, Florida (Calkins). 



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

 mens are very meager. 



L. meridionale, E. & E. Journ. Mycol. IV, p. 76. 



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

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

 Asci clavate-cylindrical, 75-90 x 8-9 fi, with abundant paraphyses. 

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

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



On rotten wood, Louisiana-. 



This differs from L. angustilabrnm, 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 Journ. Mycol., the appendages on the sporidii 

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



E. Sporidia appendiculate, 3-7 -septate.
