This well marked species is represented by four individuals, only, in the material a\ liable. Tl 
inner appendage appears to be proliferous above its base, and thus to become double, brining two sets 
of antheridia and sterile branches, an inner and an outer; the tatter arising from basal cells that are nearly 
horizontally placed. The basal region of the inner appendage is therefore very broad and cell \ of the 
larger than cells II, III, or IV. 'The tendency of the inn< i ap|x ndag 
anre 
to proliferate recalls the conditions seen in L. Triclmgnathi, though the two Sp i M s are quite unrelated 
in the section. The insertion-cell may be without any of the usually opaque suffusion, but varies in thi 
respect.

This species is distinguished by its almost falcate habit, the outer and inner hah,- of the large cured 
perithecium translucent and opaque, respectively, and distinguished by a more oi V .clean In, of dc- 
Inareation; although, in older individuals, the outer half may also become n.ther.l-ply sensed I la 
appendages in general resemble those of L perfkxa very closely, but are at once Astinguahed by tl.. , -
