Eumonoicomyces n. g. „Receptacle eonsisting of a basal and sub-

 fertile branch (abnormally more than one) tbe axis of which is coincident with 

 that of tbe receptacle from which it is not distinquished and consists of a 

 series of superposed cells which may beare a sterile appendage, an antheridium, 

 or an antheridium and a perithecium ; the three terminal cells usually bearing 

 thes organs in the order mentioned. The antheridia eonsisting of a single 

 stalk-celle and a single, often obscure, basal cell; tbe bod} r of the antheridium 

 consisiing of a series of numerous antheridial cells in four vertkal rows 

 which extend obliquely inward and upward, emptying into a comun cavity, 

 and replace entirely the two thiers of wall-cells an the antheridia of Monoi- 

 comyces ; the terminal cells growing upward directly to from four unequal sterile 

 terminal appendages, similar to those of Monoicomyces."
