290 MONOGRAPH OF THE LABOULBENIACE^. 
On LaccopMus macidosus and Hijdroporus spurius, Connecticut, Maine; Laccophilus sp., 
Kansas, Barber. 
A form peculiar for the modification of the terminal cells of the receptacle, which makes the 
peritheciuni appear as if bordered by a black band. It is found in company with C. paradoxus, 
and recalls in some respects the preceding species, which is similarly associated on the left 
elytron of its host. In one instance a few specimens were found on the left posterior leg, but 
such a position is exceptional.

Evenly suffused with dull amber-brown. Perithecium relatively large, the broad extremity 
abruptly hooked inward, so that the papillate apex becomes lateral and internal ; the external 
series of wall-cells prominent with conspicuous septa. Basal cell of the receptacle rather short, 
somewhat inflated ; the sub-basal cell much flattened ; the terminal and sub-terminal cells about 
equal in length, forming together an outwardly-curved, finger-like projection, exceeding the peri- 
thecium : a short but rather conspicuous hook-like structure (antheridium ?) arises from the 
angle between the perithecium and the receptacle on the left side. Spores, 26 X 3 ^. Perithccia, 
75 X 22 /x. Total length to tip of perithecium, 100 /i. Basal portion of receptacle, 25-30 /x long. 
On Laccophilus maculosus Germ., and Hi/droporus sjmrius Lee, Connecticut. 
This species occurs rather rarely on the margin of the right elytron in a position correspond- 
ing to that occupied by C. paradoxus, but nearer to the middle. The broad hooked apex of 
the perithecium, coupled with the fniger-like development of the distal portion of the receptacle, 
serve at once to distinguish it from known species. The hook-like projection, which arises near 
the base of the lower appendages, has already been alluded to in the previous description of the 
genus, and may be the antheridium.

Hyaline except for the suffused basal cell. Perithecium bent outward at an angle from the 
basal part of the receptacle, tapering slightly to the papillate apex. Basal cell of receptacle 
enlarged and greatly elongated, more or less intensely blackened above its hvaline base ; sub- 
basal cell flat and almost obsolete. Terminal and sub-terminal cells together funning a straight, 
finger-hke projection as long as or longer than the perithecium, on which the appendage i^ 
termnial. Spores, 33-37 X 2.5-3 ^. Perithccia, 65-90 X 30 /.. Total length to tip of pcrithc- 
cmm, 150-180 fi. Basal cell, 90-110 fi. 
On Laccophilus maculosus Germ., Connecticut. 
This species is confined 
d has onlv been 
observed upon males. It is not to be confused with any other species, being distinguished by its 
elongated basal and apical cells, almost black and white color, and papillate divergent perithe- 
cium. C. rhyncostoma, which has a very similar finger-like prolongation of tlic terminal portion 
of Its receptacle, is at once scparal)Ie by the basal cell, and the form of its perithecium.
