Perithecium wholly free, home on a short nearly hyaline stalk, slight!} line I I iili brown, for th< 
most put nearly straight, rather slender, hardly inflated, the outer margin usually slightly concave; taper- 
ing slightly and rather abruptly to the peculiarly modified tip; the tip Mark, exo pi externally immedi- 
ately about the pore, a large broad tooth-like prominence projecting inward, the upper surfa«v of which 
is nearly horizontal; while it is continued upward and outward above and beyond the lateral pore into 
a longer more slender, finger-like, bluntly tipped outgrowth, the lower or external margin of which ma\ 
be partly hyaline. Receptacle yellowish tinged with brown distally, where it if- rather abruptly, but 
lightly, broader above cell II, cell IV small and hardly longer than cell V. cells III and VI miIm-cui.mI. 
Insertion-cell opposite the distal extremity of the short j.eritliecial stalk. The basal ■ II of the outer 
appendage longer and narrower than that of the inner, becoming concolorottS With the insertion-cell, 
bearing a single branch of usually three cells more or less deeply tinged with brown, « ach of which may 
give rise distally on the inner side to a short simple branchlet: the inner appendap consisting of a basal 
cell shorter and broader, which usually bears distally on either side a branch, the basal cell of which 
usually bears distally two erect simple branchlets, one of them sometimes replaced by a single large long- 
necked brown antheridium. Perithecia, including the stalk (17 ft), 150-155 X 30 ft. Total length to 
tip of perithecium 290-310 ft; to insertion-cell 150 ft; greatest width 3.1 pu Appends) longer 200 a.

A well marked species, nearly allied to L. Javana, from which it is

Perithecium rather long and slender, usually straight and erect, free except at its very bs , evenl; 
penng 
blackish 
abruptly differentiated tip which is somewhat rounded, slightly bent inward and suffused with 
brown; the left lateral lip-cell prolonged to form a blackish blunt-tipped prominent outgrowth, which I 
either erect or bent slightly outward or inward. Receptacle dirty brownish yellow, punctate With fine 
rather indistinct transverse striations, cell V very small, often hardly visible against the pentheemm. 
Appendages concolorous with the receptacle, the outer simple, straight, rigid, mostly somewhat diver- 
gent; the inner consisting of a basal cell often as large as that of the outer, and giving nse on either 
Side distally to a branch similar to the outer ap, ndage which bear -vera lateral anthcrnha near he
