This striking species seems most nearly related to L. Ceyhncnxls\ L. spiralis and /. Vlanrlix, the aj>- 
pendages of which are very similar. Its typical form illustrated in %. 11, is very clearly distinguished 
by its free perithecium, and the peculiar conformation and coloration of the receptacle. The typei Were 
associated with a few mostly broken specimens of L. spiralis which, however, is distinguished from it bj 
the form and coloration of the perithecium and receptacle, and the relation which the former b irs to the 
latter.

Perithecium large and stout, clear transparent brown, except the subhyaline base, which is separal 
by a more or less clean-cut line of demarcation; the wall-cells with I slightly spiral twist, the tip abruptly 
distinguished, symmetrical or nearly so, black, except the evenly rounded subhyaline symmetrical hp- 
edges. Receptacle rather slender, subhyaline with pale brownish -hades; cell II twice as long as the 
basal cell; cell IV bulging rather prominently externally and more deeply suffused with brown The 
insertion-cell deep black, broad, thick. The appendages erect, their branches coned toward the peritbe- 
cium: outer appendage normally consisting of a main axis of three superposed cells, externally broadly 
blackened, the blackening involving the septa and adjacent external portions of the cells; the distal cell 
bearing three branches; an outer and an inner simple, and a median one, once branched, the outer deeply 
suffused about its base, which forms a direct continuation of the suftused external area of the mam axis; 
the remaining cells each producing a usually simple branch distally on its inner side; all the branctes 
long, slender, distally thin-walled and hyaline, curved toward the F rithecium, the tower somewhat con- 
stricted, and more Jr less deeply suffused at the lower septa: basal cell of the umer appendage hal as
