in position between its receptacle and perithecium, only the tip of which is free above cell V. The speci- 
mens from the East arc usually more deeply colored, and less yellowish, cell V often less prominent than 
in the American specimens- The appendages, though usually short or broken, as represented in my 
Monograph, are sometimes well developed, exceeding the perithecium in length, with variably developed 
basal cells. One form from the legs of M. Braziliensis (Berlin Museum No. 899) varies in its compara- 
tively short stout habit, black brown suffusions, and elongate appendages (over 200 /jl); but is associated 
with the normal type, and is merely a variation brought about by growth on the legs of its host.. Two

insert ion-cell is horizontally placed, and a third of the perithecium, more or less, is free above it. In 
these respects it is more nearly allied to L. Papuana in which more than half the perithecium is free, but 
the apex of the latter is quite different as is the general form and coloration of the receptacle.

Peritliccia free except at the base, short, stout, becoming tinged with brown, straight or the usually 
very broad tip turned slightly outward, the latter black, contrasting with the hyaline lip-edges. Recepta- 
cle elongate, faintly and uniformly tinged with smoky brown, normal, except that cell V is pushed up even 
beyond the hyaline unmodified insertion-cell which becomes thus external to it. Appendages typically 
consisting of an inner and an outer basal cell, the outer bearing a single oblique or nearly vertical more 
or less irregular row of branches arising antero-posteriorly; the inner bearing a similar row on either side, 
all the branches hyaline or yellowish brown, more or less copiously branched; the lower cells somewhat 
inflated, the septa blackened, often oblique, the basal cells of the brandies bearing distally and externally 
From one to three obliquely superposed branchlets with blackened septa, which may branch again; the 
ape ring 
A third group of branches similar to the rest sometimes arises between these and the perithecium, ap- 
parently from the distal portion of cell V. Perithecia 140-200 X 55-60 a. Total length to tip of peri-
