into little obtusely conical projections, around which the surface of the 

 matrix is of a tawny color. Asci clavate-cylindrical, 50-60x7-8 jut. 

 Sporidia biseriate, oblong, 3-septate and slightly constricted at the 

 septa, brown, 11-15 x 3-3 J //, ends obtuse. 



On petioles of Sabal serrulata, Florida (Martin and Calkins). 



This is closely allied to L. sabaligera, B. & C., but (sec. Louisi* 

 ana specc. from Langlois), differs in its rather larger, less prominent 

 perithecia and shorter, darker, constricted and obtuse sporidia. 



L. gigaspora, Niessl. in Rab. F. E. 2998. 



Perithecia somewhat scattered, globulose, sunk in the parenchy- 

 ma of the leaf, J mm. diani., with a broad, flattened, scarcely erumpent 

 ostiolum, black. Asci broad cylindric-clavate, sessile, rounded at the 

 apex, 8-spored, 144-150 x 22-24 jut thick. Sporidia 2-3-seriate, elon- 

 gated-fusoid, at first hyaline and 2-celled, finally 3-septate and some- 

 what constricted at the septa, honey-yellow, 50-55 x 10-12 p..
