This well marked species is allied to L. corethropsis and L. fissa, the general characters of the ap- 
|>eiidages being similar in all three species. The conformation of the tip of the perithecium in the present 
species, with its obliquely projecting finger-like outgrowth, as well as its general form, large 'receptacle, 
an'l small perithecium, serve abundantly to distinguish it. On the other hand it appears to be allied to 
//. Copfoilnfr from Mexico, figured in my Monograph, as are also the two other species above mentioned.

Perithecium free except the base, straight, nearly symmetrical, brown, translucent or transparent, 
paler below; the wall-cells spiral, describing about half a turn from the base to the tip, which is abruptly 
distinguished, nearly symmetrical, abruptly opaque below the broadly subhyaline, faintly brownish lips, 
which are not prominent and form a somewhat angular-truncate or very slightly oblique apex. Distal 
and basal portions of the receptacle very thick-walled, punctate, abruptly distinguished; the basal cell 
hyaline or faintly reddish brown, nearly parallel with the perithecium; thesubbasal cell larger and longer, 
more or l< s prominently and gradually constricted toward the middle; the straight anterior margin of 
the distal portion of the receptacle abruptly divergent and formed by cell VI and the secondary stalk-cell, 
both of which become deeply suffused with black brown, except the base of cell VI which is concolorous 
with the suhbasal cell, from the upper half or less of which it is obliquely separated: cell 1 1 1 and IV subequal 
and separated by a slight constriction, faintly brownish or subhyaline, their margins slightly convergent 
toward the thick, jet black, constricted, slightly oblique insertion-cell; the inner margin of which is free 
from the base of the perithecium. Basal cell of the outer appendage squarish or slightly longer than 
broad, bearing above its outer upper angle a single opaque contrasting short branch (broken in the types 
but evidently bearing several branchlets); the basal cell of the inner appendage somewhat smaller, bearing 
;i branch on either side; each branch thrice closely branched, their short basal cells, which are subhyaline 
or faintly reddish brown, each successively bearing two or three divergent stout branchlets; the series 
ending in branchlets of the fourth or fifth order, which are deep brown, slender, stilf, divergent, thirty 
or more in all. Spores 185 X 6.5 ;x. Perithecia 290-310 X 80-87 fi. Receptacle 365-540 X 150 fi.

( )ne of the largest and finest species of the genus, the three mature specimens examined being in good 
condition except that the tips of the ultimate branchlets are broken in all caa . As far as can be deter- 
mined from the specimens, one of which is quite young, the basal cell of the outer appendage bears only 
a single opaque branch, all the rest belonging to the inner appendage. Its relationships to other species 
arc not evident and it is placed provisionally near L. palmel/a and L. forficulata, both of which occur on 
allied hosts.
