faintly and uniformly tinged with smoky brown, normal except that cell I 

 V is pushed up even beyond the hyaliue unmodified insertion-cell which ! 

 becomes thus external to it. Appendages recalling those of L. variabilis, j 

 typically consisting of an inner and an outer basal cell, the outer bearing ; 

 a single oblique or nearly vertical more or less irregular row of branches j 

 arising antero-posteriorly ; the inner basal cell bearing a similar row on | 

 either side, all the branches hyaline or yellowish brown, more or less I 

 copiously branched ; the lower cells somewhat inflated, the septa black- | 

 ened, often oblique, the basal cells of the branches bearing distally and ] 

 externally from one to three obliquely superposed branchlets with 

 blackened septa, which may branch again ; the ultimate branchlets taper- 

 ing slightly, the septa transverse and hyaliue, usually cohering in an erect I 

 mass. A third group of branches similar to the rest sometimes arises j 

 between these and the perithecium, apparently from the distal portion of ! 

 cell V. Perithecia 140-200 X 55-60 //. Total length to tip of perithe- I 

 cium 475-875 ft; to insertion-cell 400-700 ^. Appendages, longest about ]

Perithecium short and broad, wholly united to the receptacle except 'i 

 the tip, clear dark brown, darker distally, the tip large, blackish, somewhat | 

 compressed, the lips translucent smoky brown, not prominently distin- i 

 guished. Receptacle short and stout, the distal jwrtion larger than the I 

 basal ; cells I, II, and VI transparent yellowish, the rest smoky brown, ! 

 marked by closely set fine transverse lines ; cells III and IV relatively j 

 very large, subequal. Insertion-cell two thirds as broad as cells IV- V. j 

 Outer appendage consisting of three superposed flat cells, hyaline becom- j 

 ing dark brown, the two lower larger and nearly equal, the middle cell 

 producing a single branch curving upward from its inner side, the third , 

 cell producing a similar branch from its inner side and a terminal branch i 

 which is deep brown curved outward and upward, slender, simple ; the ' 

 inner branches of the three cells all at first hyaline, mostly once branched, ! 

 later developing a dark brown contrasting suffusion above their basal i 

 cells : the inner appendage consisting of a small basal cell producing a | 

 branch on either side the basal cell of which is larger than that of the 1 

 appendage, and bears two branchlets basally suffused with brown like j 

 those of the outer appendage. Perithecia 130 X 50 fi. Total length to i
