On languishing and dead leaves and sheaths of Carex laevi- 

 vaginata (Kukenth.) Mackenzie, Oneida, Madison county. 

 H. D. House, June i8, 1921. 



This differs from Phyllachora graminis, which is 

 astomous and tuberculose, by its prominent perithecia. It has much 

 smaller stromata than Scirrhia ostiolata Ell. & Galw. 

 which it resembles in the cell contents. Some of the stromatic sec- 

 tions look more like Diaporthe than a Dothideaceous genus. Most 

 of the leaves were also infected with Puccinia urticata. 



Phyllachora Melicae Dearness & House, sp. nov. 



Stroma oblong, ends truncate, shining, dark brown, ^ to i mm 

 long, 160 jx wide (Avidth i -rowed loculi) to 500 11 wide (in 3-rowed 

 examples), visible on both sides of the leaf, clypeate on the upper 

 side. Loculi in one-three rows, stromatic on the upper side of the 

 leaf, globular, 88-136 fx. in diameter, base wall 25 /^ thick, side walls 

 16-18 yw thick, upper with adnate clypeus 30-35 i^ thick, of compact 

 dark colored short celled parenchyma. Asci cylindric, short pedun-
