Perithecium transparent brown, nearly straight externally, the inner margin somewhat convex; tin 
inner lip-cells deeply suffused, contrasting, coarse, erect, prominent, the lip edges hyaline outwardly 
oblique. Receptacle normal, rather short and stout, somewhat piomim itly rounded below the } h rit lu*- 
cium; cell III smaller than cell VI; cells IV and V broad, equal in length, prominent below the* broad 
insertion-cell. Outer appendage consisting of from three to four mostly roundish or Battened Super- 
posed cells, constricted at the blackened septa, which become oblique by the proliferation of each cell 
from its inner side to form a single, usually simple, erect branch; the brain-lies eventually stout, rather 
closely septate, thick-walled; the basal cell of the inner appendage half as large as that of the outer, 
producing one or more simple branches similar to those of the outer ap|>endage, and boil antheridial 
branchlets, which bear the brown, slightly curved antheridia in a rather dense group. Spores 72 X 5 ft* 
Perithecia 150-155 X 55 //. Receptacle 170-220 fi. Appendages 180-225 /<. Total length to tip of 
perithecium 250-350 /x.

The outer appendage is broken in all the types of this species which are not very young, but in the 
latter the character of the appendage is clearly shown (fig. 8); the primary axis consisting n\' short inflated 
cells, each of which is distinguished by a blackened septum and bears a branch from its inner side. The 
relationships of this species are quite uncertain, but perhaps it may be placed as well near /,. Loxandri a 
elsewhere, although the outer appendage of the latter species is simple.

Perithecium about three fourths free, suffused with brownish, translucent, the distal half narrow 
and strongly curved inward, especially at the tip, the latter externally and distally blackened, the lip-edges 
hyaline. Receptacle rather stout, pale dirty brownish; cell II basallyand distally and cell VI externally 
more deeply suffused. Cells IV and V elongated so that they become parallel and carry the insertion-oell 
upward and outward free from the perithecium. Outer appendage consisting of a rounded basal cell 
bearing a single terminal branch, the basal cell and one or two cells above it rounded, constricted at th 
mostly blackened septa, simple or each of the lower cells producing distally on the inner side a branchlel 
the branchlets and the terminal portion of the main branch hyaline, slender, thin-walled, tarring. Inner 
appendage consisting of a basal cell like the outer and like it producing a branch on either side. Spores

A well marked species, perhaps allied to L. Chmquauii, but differing in its appendages and in other 
important respects. It has been seen only in one instance among the numerous forms of iMUmirw 
examined.

Perithecium free or nearly so, slender, usually somewhat curved inward, becoming evenly suffused 
with pale-olive brown, the broad tip not differentiated from the body of the perithecmui, the lip-cells more 
or less suffused with darker brown. Receptacle pale yellowish, often elongate, the basal iceu short; eel 
II several times as long, becoming amber-brown with transverse striatums; cells III and \ I about equal, 
elongate. Insertion-cell not deeply blackened. Outer appendage consisting of a usually somewhat ...- 
flated basal cell with thick outer wall, bearing a branch terminally distinguished by a thin black septum
