This singular-looking species occurs, so far as I have observed, only on the right side of the 
lower surface of the thorax in small groups. Its very largo antheridial appendages distinguish 
it from other species, and give it the Y or Y form which lins suggested flic specific name. The 
spores, like those of C. contortus, arc peculiar in that the sciitum involves also the gelatinous 
envelope. It seems to be a decidedly rare form, and with C. humiUs and the last mentioned 
species, all occurring on the same host, has been thus far found only at Kitfery Point, Maine, in 
a small pond near the highest point of Cutts Island.

Hyaline, becoming very faintly brownish. Receptacle consisting of three superposed cells, 
above which three cells form the general base of the perithecium and appendage. Perithccium 
long and slender, usually constricted at the base so as to appear short stalked, slightly inflated 
and bent outward, the apex pointed and curved. A short appendage arises sub-laterally below 
the apex and is strongly curved, extending inward beyond the apex, its fifth and sometimes also 
its sixth cell producing from its upper surface a stout branch which may be simple or may bear 
secondary branches at irregular intervals. Antheridial appendage consisting of about twelve 
superposed cells, producing a few branches from its inner side at irregular intervals, the branches 
in turn more or less irregularly branched. Spores, 80-85 x 3-3.5 /i. Pcrithecia, 200-260 x 35- 
45^. Receptacle about 125/1 long. Antheridial appendage, 110-130 /*. Perithecial apitend- 
age, 75 /x long.

This species is somewhat more frequently met with than the preceding, and is usually found 
on the lower surface of the abdomen on the left side near its tip. It is readily distinguished 
from C. furcatus by its more slender habit, almost stalked perithecium, much smaller appendages 
and generally malformed and distorted habit. It has as yet been found only in the locality men-
