This species is closely allied to /.. leucopkcea and L. oorrugata, being the least chaiacteristie ( .f the 
three. It is distinguished from /,. leucopkcea, which it most nearly resembl s in the relation of its |ht'i- 
thecium to the receptacle. The short basal cell of the latter, the pmutation of tin- Hibbasal cell in 
connection with its suffusion, and in the very differently shaped peril heeial tip, which is without am 
finger-like projections.

Peritheeium dark brown, almost opaque, rather small, baldly more than the tip free from the rv<rp- 
taele; the tip relatively large and long, bent slightly outward, not abruptly difTerentiatt <1, black except 
around the pore, the right inner lip forming a hyaline nearly median blunt outgrowth which is bent slight l\ 
outward. Receptaele sometimes twisted at the distal end of and above cell 11; cell 1 hyaline; cell II 
suffused with brown, in some cases with deeper brown transverse elevations (in one side; the lower half 
of cell III and cell VI hyaline, the rest of the reeeptacle coneolorous with the peritheeium. The outer 
appendage simple, its basal cell four or more times as long as broad, curved toward the j ritheeium; the 
basal cell of the inner appendage very small, bearing in general a single short branch, both apj>cndag< s 
pale yellowish. Peritheeium to tip of outgrowth 130-150 X 35-40//.. Total length to tip of perithe- 
eium 325-375 /,<; to insertion-cell 250-290 /<; greatest width 55-65 /x. Appendages about 2(H) //.

Tins species is closely allied to L. corrugate and L. tuberculifera, but differs from both in the rela- 
tion of its peritheeium to the receptacle, and the conformation of the tip. Of two original preparations 
one has unfortunately been destroyed, so that the species is represented by two individuals only.

Peritheeium rather small, irregular, free from the receptacle except at the b blackish brown, 
darker and almost opaque below, a rounded distal elevation extending completely around the pcrithe- 
eium, broader externally, forming a nearly opaque broad collar, above which the tip is very abruptly 
distinguished; the latter subhyaline basally, a dark median external and internal suffusion, the lip 
bctw 
form two free slightly unequal divergent blunt-pointed projections. Receptacle rather long and llendei 
pale brownish yellow with deeper brown suffusions about the distal region of cell I and the D* tl region 
of cell II; the basal cells of the peritheeium opaque and cell IV and V more deeply suffu I; a scri, of 
prominent blackish brown tuberculate ri( 
anterior margin, beginning below the insertion-cell and extend as far as the b. e of cell II, Q 11 IV bulging 
distally outside the thick rather narrow insertion-cell. Outer appendage simple, erect, tapering, yel- 
side. Peritheeia 120 X 37-40
