the three well marked species here (numerated in a group l.y themselves. As the venter of the |m ritln 
eiuin develops, the whole base of the appendage becomes incorporated with it, as well a* the 1 il n lit 
of its lower branches, which actually, in the end, form a portion of tl peritliecial wall mil < m lo an > 
as is shown in Plate LXVIII, fig. 5, from wall-cells above the base of the main appendage. Tin 
or trunk-like prolongation of the perithecium is most characteristic, and at maturity Im<<,i * *) uptljf

outgrowths below the curvature. The known species all inhabit water lxrtli belonging to the I! 
drophiliche, and have been found in North America and ( )c< aniea.
