appciiclagc distinctly constricted at the joints, or may be more or less copiously branched. The 
inner basal cell bears one or two short branches, from which arise small dense clusters of brown- 
ish antheridia, and rarely a more elongate sterile branch. Receptacle rather slender, a more or 
less well marked brown suffusion usually present in the distal portion ; sometimes wholly suffused 
with brown. Spores, 45 x 4 yu. Perithecia, average, 85 X 30 /i. Appendages, longest, 300 fx. 
Total length to tip of pcrithecium, average, 200-220 /t.

defined to warrant Its separation as a distinct species. It is nearly allied to L. 
may prove a variety of this species. A form apparently identical with it occurs on several 
s])ecies of Loxandrus from Florida and Texas. The specimens on Badister arc more or less 
evenly suffused with brownish yellow. It varies very greatly in tlic character of its outer 
appendage, which may be quite simple, as in fig. 18, or may often be rather copiously branched, 
resembling almost exactly the outer appendage of fig. 13 (X. tenninalis) ; its ultimate branches, 
however, are never as long as in this species. Its antheridia are usually densely clustered In a 
tuft, the inner appendage only rarely producing elongated sterile branchlets. The perithecia are 
almost invariably blackened externally near the base, and usually bulge slightly at tliis point, as 
indicated in the figure which represents only the more simple type. The affected hosts arc 
found in various situations, under stones or in rubbish, very often in rather dry situations. 
The determination of the specimens on Amara is not yet quite definite, since they vary sliglitly 
from tlie American form.

Pcrithecium deeply suffused with smoky brown, slightly inflated, the inner margin evenly 
curved outward, the outer more nearly straight, but bent abruptly outward to the large promi- 
nent apex, the hps of which are well defined and outwardly oblique. Appendages arising from 
two basal cells, a very large outer and a much smaller inner; the outer giving rise to two cells 
each of which bears terminally from two to three long, slender, tapering, flexuous branches 
tugged, at least basally, with reddish brown; the inner bearing a single eell, as a rule followed 
by two, terminal cells which give rise to groups of two or three rather slender sessile antheridia ;
