This curious form is chiefly remarkable for the peculiar conformation of the tip of its perithecium, 
(he outgrowths from which are more highly developed than they are in any of the other terrestrial forms. 
It is most nearly related to L. Sumatra, in which the tip of the perithecium is somew r hat similar, though 
It s peculiarly developed.

Perithecium small, pale amber-colored, darker and somewhat inflated below, tapering distally; 
the tij), only, free from the receptacle, not distinguished from the body of the perithecium, long, nearly 
hyaline below, tin- lip-colls abruptly spreading, contrasting, black except about the pore and peculiarly 
modified, the two outer broadly rounded, the two inner developing outgrowths which grow inward and 
upward; that on the right side longer than the left, narrower and indented near the base on the inner side. 
Receptacle concoloroufl with the perithecium, paler below, marked by faint fine transverse striatums. 
Appendag concolorous with the receptacle, the outer simple, stiff, curved slightly outward, the inner 
consisting of a basal cell smaller than that of the outer and bearing on either side a branch which may be 
once branched at the base. Perithecium 92 X 22 fi. Total length to tip of perithecium 200 fi; to inser- 
tion-cell 106 //. Appendages about 185 /t.

This little species is intermediate between L. tenuis and L. Javana, approaching the latter very closely, 
though differing in the peculiar conformation of the tip of the perithecium and the relation of the latter 
io the receptacle, which is normal in form, and undistorted. The outer appendage also differs in being 
straight, with a relatively smaller basal cell.

Hyaline, becoming very faintly tinged with yellowish brown. Perithecium about one half or more 
free, slightly divergent, short, stout, tapering slightly from the broad basal half to the tip; which is, as a 
rule, bent abruptly inward, rarely outward, or erect, rather small and well-distinguished by its long external 
contrasting broadly blackened margin, and by a shorter broadly blackened area below the small, promi- 
nently rounded inner lips; the lip-edges horizontal, or nearly so. Receptacle rather long and slender; 
cells I and II of nearly equal diameter, the latter large; while between it and cell III and VI the receptacle 
may be abruptly and strongly twisted; cells III and VI subequal, the former higher; cell IV slightly 
mailer; cell V relatively large, the inner half or less of its inner margin free between the perithecium and 
the broad, thick, black contrasting insertion-cell. Outer appendage consisting of three superposed, dis- 
twice as long
