which is rather small and thick; deep, slightly reddish, brown, the deep suffusion continuous with a 
corresponding external coloration of the basal cell of the outer appendage and the three to four lower cells 
of the <»utcr branch, which arises from it and which curves more or less strongly outward; the distal por- 
tion curved upward, hyaline, tapering, flaccid, each of the suffused cells giving rise distally, from the inner 
side, to a more or less erect, simple (or the lower sometimes furcate) hyaline branchlct, the lower cells of 
which are rather long and slender, inflated; the distal portion tapering, thin-walled, usually becoming 
flaccid; the inner bianch of the appendage furcate above its erect basal cell, the branchlets divergent and 
similar to those of the outer branch, or short and bearing antheridia usually in pairs; the inner appendage 
consisting of a basal cell about as large as the outer, bearing a hyaline branch on cither side which is usu- 
ally furcate above its basal cell, the branchlets similar to those of the outer appendage. Spores about

ime respects not unlike L. Caxnonice. Its appendages, however, belong to the 
type illustrated by L. Planetis and L. Helluodis, and easily distinguish it from any of the forms of L. 
polyphaga, or of other species with which it might possibly be confused.

Perithecium hyaline, becoming tinged with brown, less than one half free; short, the outer margin 
nearly straight, bending rather abruptly inward at the tip; the inner margin converging to the apex from 
its point of union with < 11 V; the tip rather abruptly distinguished, broad; the apex nearly flat, the lips 
hardly prominent. Receptacle yellowish or hyaline, with faint brownish shades; the basal cell usually 
bent, the subbasal with deeper brown suffusions; cell III more or less deeply suffused with brown, its 
thick outer wall opaque or nearly so; cells III and IV subequal, several times longer than broad; cell V 
long-triangular. Insertion-cell thick, black, contrasting, wholly free, separated from the perithecium 
by nearly the whole upper margin of cell V. Outer appendage curved strongly outward, hyaline on its 
inner side, deeply suffused on the outer concave side, the suffusion continuous with the insertion-cell; 
consisting of a small Dumber of cells, the basal relatively long, the rest producing suberect hyaline branch- 
lets distally on the upper side: basal cell of the inner appendage smaller, the subbasal -cell usually bearing 
two branchlets. Spores 50 X 5 a. Perithecia 65 X 25 /i. Receptacle 100-110 /*. Appendages 50-75 fi 
approximately. Total length to tip of perithecium 130-140.

In the types of this small and peculiar species, the appendages are more or less broken, even in the 
youngest specimens- It is distinguished by the conformation of the distal portion of the receptacle, and 
the dee]) Literal suffusion of the latter, as well as by the entire absence of suffusions even at the tip of 
its perithecium. The spores are large for so small a form, nearly equalling the perithecium in length. 
It does not appear to be nearly related to any other described species.

Perithecium becoming ri.h brown, free, usually somewhat broader distally, slightly inflated; the 
basal-cells forming a clearly denned, somewhat constricted, short neck; the tip abruptly distinguished, 
went very slightly outward, opaque except the broadly hyaline or subhyaline, broadly rounded lips. Basal 
cell of receptacle hyaline or subhyaline, inflated, broader than, and contrasting with, the opaque sub- 
basal cell, wlueh is of about equal length and forms a constricted region; the distal portion of the re- 
ceptacle small, rather abruptly broader, sub-triangular, the external margins even; cells III, IV and VI 
su hequal, more or less deeply suffused with brown; cells III and IV more deeply suffused externally, about 
halt the upper margm of cell IV free and forming a distinct prominence external to the jet black insertion
