Laboi lbenia rhinophora Thaxter. Plate LXV, figs. 8-9. 
Proc. Am. Acad. Arts and Sci., Vol. XXXV, p. 199. Dec, 1899. 
Perithecilim large and stout, dirty smoky brown, the lower half much deeper and united to the recep- 
l.irlc, the base nearly opaque, one of the suhterminal wall-cells forming a terminal blunt finger-like brown 
outgrowth, close beside the rather small internally blackened tip, which it exceeds in length. Recep- 
tacle stout, the basal cell small hyaline; a blackish brown suffusion becoming opaque involves the upper 
part of cell II, cells III, VI, and VII, as well as the basal cells of the perithecium; cells IV and V very 
large and nearly parallel, translucent; the suffused parts, when not opaque, marked by darker trans- 
verse dots and strhe. Insertion-cell very large, triangular, quite unmodified. Appendages consisting of 
two basal cells concolorous with insertion-cell, the outer usually somewhat larger, both protruding up- • 
ward and slightly overlapping, producing directly numerous branches (four to eight from each cell) which 
arise in more than one row from their outer surfaces; all the branches once to twice branched, the lower 
Segments deeply constricted at the purplish septa, the distal cells without constrictions at the hyaline septa. 
Spores 75 X 5 fi. Pcrithecia to tip of protuberance 275-300 X 85 fx; to insertion-cell 300-340 \i. Ap- 
pendages about 200 fi. 
On the legs of Brachinus sp., Hope Coll. No. 252, Madagascar. 
Three mature and one young individual of this peculiar species have been examined, the former 
all considerably injured. It is most nearly allied to L. Japonica from which it is distinguished by the 
form and peculiar modification of its perithecium, as well as the relation of the latter to the receptacle 
and by the monstrous development of cells IV and V of the receptacle.

Perithecium opaque, nearly symmetrical, rather long and slender, straight, the lower half slightly • 
inflated; tapering very gradually distally to the broad, truncate often symmetrical tip, which is barely 
differentiated above an inconspicuous elevation; the flat lip-edges slightly translucent brown: the basal 
cells forming a well distinguished short hyaline stalk, the curvature of which bends the perithecium away 
appendag 
Appendages forming a dense rather short slightly spread- 
ing tuft, the axis of which is coincident with that of the receptacle, copiously branched, the branchlets 
unilaterally disposed, rather closely septate; the septa mostly dark brown, except the very numerous 
paler slightly tapering extremities, which hardly reach the middle of the perithecium. Receptacle sub- 
clavate. the b* il cell rather large, hyaline narrower below; the cells above yellowish brown, incon- 
spicuously punctate; cells III and IV bulging symmetrically and prominently below the well-defined 
msertion-c«ns; cells IV and V separated by a nearly vertical septum. Perithecia, exclusive of stalk, 
" ft stalk 25 X 30 ft. Receptacle 150-185 X 55-05 p. Appendages (longest) 125 ft.
