Distinguished from the preceding species bj its pale yellowish color, conical, nearly straight 
perithccium, and by the elongated basal cells of the latter. 
The two varieties of this form represented in figs. 5 and 6 occurred together on the abdomen 
of the same individual ; and though the blackened form mn y be taken as the type, it is im])rob- 
able that the two are distinct, since similar variations in color arc common in other cases.

Receptacle consisting of two superposed cells, the distal producing one or more stalked peri^ 
thecia, and one or more antheridial appendages. Pcrithccia sub-conical, boiiic on a sin^dc 
stalk-cell surmounted by three basal cells. Antheridial appendages consisting of two supcj-poscd 
cells, terminated by one or two cells which may bear scvernl branches, the snb-ltasal cell 
divided into two parts longitudinally or obliquely, one of which (the anthcridium) is subdivided 
by anastomosing septa into numerous small cells. Spores once septate. Trichogyne 
filamentous. 
This genus is very closely allied to the preceding, differing only in the fact that the anthc- 
ridium is not terminal, but lateral, on an appendage terminated by sterile branches and destitute 
of the spine-like process characteristic of Haplomyccs. The general relations of its parts arc 
otherwise similar, and its anthcridium possesses the same characteristic irregularly honey- 
combed structure. In C. Bledii, the only species abundant material of which has been examined, 
two or even three perithecia may arise from the same receptacle, and very rarely two append- 
ages. In the absence of fresh material, except in the case of the very minute C. pusillm, the 
exact nature and relations of the spermatic cells remains a matter of doubt. In one specimen 
of C. Bledii, a well-developed trichogyne is present, rather copiously branched and bearing no 
resemblance to the greatly reduced type characteristic of Peyritschiella and its allies. As in 
Haplomyces, there appear to be eight ascogenic cells, but this point has not been definitely 
determined. The species all occur on beetles belonging to the Staphylinidia).

Color pale yellowish. Perithecia sub-conical, nearly symmetrical, basally inflated, borne on 
a well-developed stalk-cell surmounted by three smaller basal cells, one to three arising from 
the sub-basal cell of the receptacle. Receptacle consisting of a basal and somewhat larger sub- 
basal cell ; often deeply and broadly blackened externally and inferiorly, in which case it pro- 
jects laterally. Appendage usually single, rarely two arising from the same receptacle;
