Short, stout, pale yellowish with brownish tinges. Peritheeimn free, straight, very slightly narrower 
distally, the distal portion, except externally about the hyaline pore, dee]) black, the suffusion extending 
less than half-way down externally, and about a third on the inner side: the distal end broad, flat, pro- 
jecting on the inner side to form a rounded prominence; the pore lateral and external, hyaline, with 
adjacent paler shades; the black, slightly projecting area below it forming a more or less dean-cut line 
of demarcation. The receptacle short and stout; cells I and II Bubequal, a> are also cells III and IV. 
Appendages as in L. orientalis, hyaline, the two basal cells partly overlapping and bearing each four to 
five branches four to five times branched, the cells distinguished by constrictions and blackish septa.

This very peculiar little form is most nearly related to L. orientalis of which it may possibly prove 
to be an abnormal condition. It is however quite unlike the smaller forms of this species which grow 
in similar situations, and the types show no tendency to vary toward the normal form, even very young 
perithecia exhibiting the very peculiar conformation represented in fig. <>.

Short and stout, unevenly suffused with smoky or faintly olive brown. Perithecium relatively very 
large and long, more or less distinctly curved toward the appendages; the base subhyalim tb body 
evenly dark, slightlv olivaceous brown, scarcely inflated, tapering very slightly to the stout, evenly 
rounded, opaque, hardly differentiated tip; the longitudinal serio of wall-oils slightly spiral, describing 
about one quarter of a turn or somewhat more. Receptacle relatively small, short ami .Mont, the basal 
and subbasal cells hyaline, contrasting, the latter somewhat larger, separated by an oblique partition 
from cell III, which 'is small, subtriangular and deeply suffused; cell IV larger, suffused, as IS cell \

unmodified. Basal cells of the outer and inner appendages vertically elongated, each bearing cxternalb 
and distally a series of four or five superposed branches distinguished by blackened septa, curved out- 
ward and often downward, and branching in a radial plain, the branch, two to four times .ranched. 
forming a compact tuft, the basal cells usually b iring three branchlets, the further division of wnict.

This is a striking species allied to I, orientalis and more closely to L. rlnnophora, which has h- 
same peculiarly developed receptacle in which cell VI extends downward to cell I, although . lack, he 
monstrous development of cells IV and V peculiar to this species. The penthecium ,s also quite d < r . 
and unlike any forms of L. orientalis, both in form and relative size. The appendage- projed outsu* 
horizontally in a compact mass, with a tendency to recurve, and the branching is in a plane coincident
