Sporangia stipitate, splitting in an irregular or reticulate manner, 

 without columella; \vall of sporangia single, very delicate, weakly, 

 but not uniformly containing deposits of lime; tubes of the capillitiimi 

 at the bottom simple, forking through the whole length at a sharp 

 angle, the rest straightened, therefore formed into a regular net ; 

 grannies of lime very small, fusiform, not numerous. Rtfki. Mon.,
