More or less sufTuscd with faintly olive brown. Perithecium rather large, the apex, ^vhich 
is bent slightly outward, dark, the lateral lips forming a slight angular prominence over the lat- 
eral external pore. Appendages two, the outer single, curved outward, blackened externally or 
wholly opaque, giving rise from its convex side to several successive branches rather irregular in 
outline and often once branched above their basal cells. Inner appendage consisting of a larger 
basal cell, which gives rise from its apex on either side to a branch, these two branches in 
turn successively several times branched, but in a plane at right angles to their own ; the lower 
cells more or less deeply suffused or externally blackeucd. Receptacle normal, cell II of Inrge 
diameter. Spores, 40 x 3.5 ^. Perithecia, 100-110 x 33-35 /^. Appendages (longest), 150 /.t. 
Total Icugth to tip of perithecium (average), 200 fi.

\ This species docs not appear to be very closely allied to any other form known to me. Tlic 
appendages are not unbroken in any of the specimens, but appear to be decidedly characteristic 
in their mode of branching. The knob-like tip of the perithecium and the rather abrupt enlarge- 
ment of the receptacle above the basal cell also render it peculiar in general appearance. The 
tvpcs were found along the outer margin of the hosts' elytra.

Perithecium wholly suffused with blackish brown, short, its upper half free, the outer edge 
abruptly curved inward to the base of the very prominent apex, the lips of which are brown, 
bhghtly pointed. Appendages two, hyaline, almost distinct above the Tcry broad black insertion- 
cell, the outer broad at the base, tapering distally, strongly curved inward, rather closclv sep- 
tate, a small cell opposite each septum on the convex side, bearing a single short simple branch 
rather closely septate, hyaline, blackened and constricted at the base, directed obliquely 
upward The inner appendage similar, except that a cell is present opposite the first septum 
at the base on the inner side, which bears a single antheridium or a very short fertile branch. 
Receptacle abruptly expanded above cell II, cells I to VI hyaline, the rest blackish brown ; cell 
V greatly enlarged, so as to throw the appendages outward, separating them by nearly its whole 
Width from the perithecium, its free upper surface forming a right angle with the straight inner 
margin of the perithecium ; cells I and II rather slender. Perithecia, 130-150 x G5 ^. Append-
