thecium; the three terminal cells usually bearing these organs in 
the order mentioned. The antheridia consisting of a single stalk¬ 
cell, and a single, often obscure, basal cell; the body of the auther- 
idium consisting of a series of numerous antheridial cells in 
four (?) vertical rows which extend obliquely inward and upward, 
emptying into a common cavity, and replace entirely the two tiers 
of wall-cells and the antheridia of Monoicomyces; the terminal 
cells growing upward directly to form four unequal sterile term¬ 
inal appendages, similar to those of Monoicomyces.”

Antheridia simple. 
“Male individual consisting of several (four) superposed cells 
terminated by a characteristically modified spinous or small foot¬ 
like procees or by both; the basal cell attached by a small normal 
foot: one or more of the distal cells giving rise to short branches 
which may bear from one to several antheridia terminally, or 
become more or less copiously branched; the branchlets terminated 
by antheridia, or in some cases sterile. Antheridia long, flask¬ 
shaped. The subbasal cell of the receptacle sometimes producing 
a fertile branch as in the female individual from which are pro¬ 
duced secondary receptacles which give rise to antheridial 
branches. 
“Female individual consisting primarily, as in the male, of 
several superposed cells similarly modified at the tip, and attached 
by a small normal foot; the basal and subbasal cells constituting 
a “primary receptaclethe latter giving rise to a variably devel¬ 
oped fertile branch (sometimes apparently dividing to several 
cells each of which may produce a fertile branch) from which is 
developed a “secondary receptacle,” or, as a result of branching, 
more than one. Secondary receptacles consisting of a partly 
double series of cells, variable in number, one or more of which 
may be fertile, the rest sometimes specially differentiated, or un¬ 
modified ; those in contact with the host perforating the chitinous 
integument by means of fine haustoria. Trichogynes short fila¬ 
mentous. Perithecium borne on variably developed stalk-cells, 
the ascigerous portion including three tiers of wall-cells, more or 
less clearly distinguished from the distal portion, the wall-cells 
of which are more or less differentiated, four or five in each row.
