species, except that the range of C. puxillus is extended to Florida, where specimens were obtained on 
the margin of Lake Eustis, at Enstis. Specimens of C. Bledii were also obtained in the collection of the 
National Museum on Bledvus annularis Lee. from Iowa, and on B. niiidwollis Lee. from Michigan. 
The generic type is a clearly defined one, but the species are very variable in respect to the number 
of antheridia] cells in the lateral group, which is characteristic in all cases. An extreme case of this varia- 
tion is seen in the species described below, in which the antheridium proper is made up of perhaps not 
more than three or four cells.

Yellowish with a brownish tinge. Receptacle consisting of a small basal cell and a subbasal cell 
more tlinn twice as large, bearing the perithecium and appendage. Perithecium borne on a rather long 
stalk-cell, the basal cells continuous with its main body which is inflated below, conical above, the narrow 
apex truncate or bluntly rounded. The appendage large, its subbasal cell nearly twice as long as the 
basal, bearing the very small antheridium which forms a short cellular margin below its upper inner angle 
and apparently consists of not more than ten cells; the subbasal cell terminated by an irregular series of 
small cells which appear to produce a tuft of branches distally, and from which it may sometimes be 
eparated by a third cell similar to it. Perithecia 80-86 X 35 jx. The stalk-cell 55 X 20 ft. Receptacle 
50 70X28 0. Annendaces 140-170 it.

This species is most nearly related to C. occidental is which it closely resembles in general form. It 
is distinguished, however, by the greatly reduced antheridium, which can sometimes hardly be made out 
in mature specimens, as well as by the distal enlargement of the basal cell of the appendage. The material 
of this species is unfortunately scanty and in poor condition, the sterile terminal branches of this append- 
age I >eing broken off in every qase.
