Smoky olive-brown. Perithecium tapering more or less symmetrically from its lower third 
to tlie coarse blunt apex, which is not clearly distinguished from it, one of the lip-cells forming 
a short but distinct pointed median projection. Appendages formed as in L.fumosa, hut the 
ultimate branchlets strongly curved towards and often past the perithecium. Eoroptacle incon- 
spicuously punctate, stout, the basal cell slender and nearly hyaline below, the sub-basal large, 
as broad as it is long, separated from cells III and VI by nearly equal oblique septa. Spores 
about 50 X 4.5 fi. Perithecia, 110 X 40 /x. Total length to tip of perithecium, 220 /x. 
Oliv., B. lipunctatum Duft., B. fiammulatum Clairr. Europe. On 
several species of Bemlidium, Maine, Connecticut, and Washington. 
This small species is not uncommon on Bembidia about ponds and streams, though it is sel- 
dom found in great numbers or in verv good condition. It grows in a small dense tuft at the

tips of the elytra like the preceding species, with which it is closely allied, though readily 
separated by its curved appendages. The receptacle where it is suffused is rather obscurely 
punctate.

to the rather stout tip, the lip-cells not clearly distinguished, turned slightly outward. Append- 
ages as in the preceding species, the insertion broader, the main branches more numerous, the 
ultimate branchlets forming a dense tuft, rigid, erect, tapering slightly, hardly equalling the tip 
of the perithecium. Receptacle short and distally very broad, cells Ill-Y about equal in size. 
Spores, 60 X 4 ^. Perithecium, 110 X 40 ^. Appendages, 90-100 /x. Total length to tip of peri- 
thecium, 180-190 /x; greatest width, G5 /t. 
On Bemhidium sp., Maine and Massachusetts. 
This species, though closely allied to L. luxurians, seems constant, and is undoubtedly dis- 
stout form and rigid, erect, tapering appendages, which 
uic mucn more numerous than in its ally. The perithecium and receptacle arc also dififerently 
shaped and never so deeply colored. It occurs not uncommonly at the base of the posterior pair 
of legs of its host.
