Perithccium black, almost opaque, rather narrow, the inner margin curved abruptly outward 
to the rather large apex, the lips very obHque outward. Appendages arising from two basal cells 
which are nearly equal in size : the outer inflated and separated from the cell above it by a 
blackened septum, this sub-basal cell roundish, inflated, about as large as the basal cell and giv- 
ing rise to two branches, an outer and an inner ; the outer separated from it by a blackened 
septum and consisting of a basal cell with three terminal branchlets, the inner of which is 
deeply and broadly blackened at its base, while the other two are wholly hyaline and fertile; the 
inner branch from the sub-basal cell has no blackened basal septum and produces several short 
branchlets bearing numerous antheridia. The inner appendage, like the outer, consists of a 
roundish or squarish basal cell separated from a sub-basal cell by a blackened septum ; the 
sub-basal cell producing a tuft of short branches bearing at their tips two to four antheridia 
or becoming more elongate and sterile. Receptacle normal, the two basal cells rather slender, 
elongate, colorless ; the distal cells suffused with blackish brown, rerlthecia, 110-120 X -40 fi. 
Appendages (longest), 240 /i. Total length to tip of perithecium, 333/*; greatest width, QS fi. 
On Asjoidoglossa mhangulata Cliaud., Kansas (M. A. Barber). 
A species clearly marked by the peculiarities of its appendages, which, unlike almost all 
other species of the genus, are fertile without regard to their external or internal origin. In 
this respect they resemble L. Glivince, which is found on a closely related host. Otherwise its 
relationship to other described species is not evident. It occurs rarely on the host mentioned, 
usually not more than two or three on a given specimen.

Proc. Am. Acad. Arts and Sci. Vol. XXVIII, p. 1C9. 
Color pale straw-yellow to reddish. Perithecium short, stout, united to the receptacle for 
three quarters or more of its length ; its free portion abruptly tapering to the rather small 
tip ; the lip-cells turned slightly outward, with a blackish suffusion below on the inner side. 
Appendages united to form a single brush-like organ without any blackened insertion-cell, and 
consistmg of a basal cell which may be single or longitudinally several times divided, followed 
by a second series of two or more elongate cells placed side by side and bearing distally a series 
of branches which, by branching several times successively, form a douse tuft; the ultimate 
branchlets slender and curved, sterile or fertile. Receptncle moderate, normal, except that 
col s n and V become irregularly divided into often numerous (four to eid.t) cells which vary 
in form,^size, nun^.er, and position in different specimens. Spores, 75 X 6^;.. Perithecia, 145- 
150 X 5O-60 ^. Appendage, 110-200 ^. Total length to tip of perithecium (longer), 400 /..
