Perithecium free, long and narrow, evenly tinged with transluoent olive-brown except tin shorl 
somewbat constricted hyaline neck, the tip well distinguished, blackish brown, bent outward, (he lips 
coarse subhyaline oblique outward. Receptacle Dearly hyaline, except cell II. and sometimes (he upper 
part of cell I which is suffused with dirty olive-brown and faint 1;- punctate with fine transverse stria*, loi 
and slender, geniculate above cell II. Insertion-cell broad, black, close to base of ]>erithccial neck. < Kiter 
appendage consisting of a larger basal subtriangular cell becoming more or 1< utfnsed with olive-brown, 
its outer edge straight, surmounted by a series of five or six obliquely superposed hyaline eells which curvet 
inward toward the perithecium; each cell of the series bearing externally a simple branch consisting of 
two short faintly brownish basal cells constricted at the blackish septa, and a terminal hyaline tapering 
portion about twice as long: the inner appendage consisting of a basil cell blackened below , from which 
arises on cither side a scries of superposed cells like that of the outer appendage and similarly branched, 
except that one or two of the lower cells of the scries bear antheridia, solitary, on a unicellular stalk. Peri-

The material of this form is not abundant, but all the specimens examined have tin line geniculate 
habit and show no variations. The species possesses no very striking individual characters except its 
geniculate habit, which may prove inconstant; yet it does not seem possible to refer it to any of the other 
described species. It is most closely allied to L. adanea, the distinguishing points of difference in wind, 
have already been referred to under that species.

Perithecium erect or slightly divergent, evenly suffused with rather pale or rarely darker translucent 
dirty brown, considerably, often almost symmetrically, inflated, slightly broader below; the basal wall- 
cells forming a short, often almost obsolete, hyaline stalk; the tip rather abruptly distinguished, usually 
bent slightly outward, short, stout, wholly suffused with brown, darker below; the apex evenly rounded 
as a rule; the outer lip-cells curved outward to the external pore, slightly prominent. Receptacle normal, 
hyaline, or faintly yellowish; the distal portion short and broad; the Da .1 ceD relatively short: cells MI 
and IV subequai. The insertion-cell slightly oblique, black, contrasting, the opacity usually involving 
a part or the whole of the basal cells of the outer and inner appendag 8. Appeal similar to those of 
L. perplcxa, more compact, with shorter branches; outer appendage consisting of about six to eight 
obliquely superposed cells, the branches divergent, curved upward; the two cells of tb basal part stout, 
Clear brown, constricted at the dark septa, roundish to long-oblong; the distal part rather Stout inner hilar 
tapering to a blunt apex and seldom reaching beyond the tip of the perithelium; tl two branches o I 
the inner appendage similar to the outer, except that the two lowest branches consist of a singte cell, H 
ba>al septum alone dark and constricted, bearing distally a single rather short, ^hghtly curve, brown 
antheridium. Spores 95-100 X 8 p. Peritheda 185-250X60/1. Receptacle 185-290 X 70-*> * 
Appendage 200-250/1. Total length to tip of perithecium 360-500 p.

This species appears to be allied to L. perpfem, with which it was asso, .ated on die same host m 
company with /.. iLlor, L. corniculala and L. fudfarmU. It differs, however, m its short . ncarh eve u
