gated through the appearance of three to five rather broadly rounded successive elevations, corn (ponding 
to the distal and basal septa of the two lower tiers of wall cells, and to a median protrusion of these cell 
where five are present; stalk-cell becoming slender, mostly slightly shorter than the receptacle; the basal 
cells small. Receptacle relatively rather long, the cells nearly equal. Appendage generally longer than

head cell; the discharge-tube large, bent outward or obliquely upward. Spores SO X I ". IVrithccia

A few individuals of this species were found at the base of the eltyra of the host. It is well marked 
by the abrupt distinction between the base of the perithecium and its stalk-cell, by the broad tip and 
stout somewhat irregular form of the latter, and by the small number of the antheridial cells.

Additional material 
ial of this species has been obtained on specimens of Atranvs pub, ftfl from Wa 
incrton, D. C, and from Kansas, in the collection of the U. S. National Museum. As this material is ve 
much better than the types, both of which were immature or injured, additional figures arc given ben

The antheridium may be distinguished by a slight terminal apieulu It should U noted [thai the margi- 
nal cell of the antheridium is not septate above, as represented in Plate VII, fig. 27, of my Monograph.

rather abruptly distinguished externally, sometimes bent outward, its distal margin outwardly obhqu.
