elevation; the tip very broad, Bhort, almost flat-topped, the outer at ._ 

 almost a right angle, the inner rounded. Receptacle consisting of a basal 

 cell which is nearly hyaline, above which cells II. III. and VI form an 

 almost transverse row; cell II median, triangular, lying between the 

 other two, the receptacle abruptly expanded in this region; cells III and 

 I V Bmall and flattened; cell V hardly distinguishable, [nsertion-cell 

 and basal cells of the appendagi - nearly opaque and indistinguishable 

 from one another, the outer basal cell apparently producing two brand 

 antero-posteriorly ; the inner a branch on either Bide, all the branches 

 (broken) brown, still', erect or slightly divergent. Perithecium 185 X 

 66/t. Total length to tip of perithecium 295 p.; to insertion-cell 90/ij 

 greatest width 65 u.

Perithecium five, becoming olivaceous brown, mostly Btraight, the 

 basal wall-cells forming a very short stalk, the tip rather abruptly distin- 

 guished, mostly straight symmetrical black, distally hyaline. Receptacle 

 olivaceous yellow with brown sutl'usious ; cell I slightly Buffused with 

 brown, somewhat longer than cell II, both rather narrow ; the receptacle 

 expanding rather abruptly above cell II; cells III, IV, and V nearly 

 equal becoming rather deeply suffused with brown. Insertion-cell broad, 

 blackened. Outer appendage consisting of a large triangular basal cell 

 becoming deep blackish brown, above which four to six small nearly 

 hyaline cells obliquely superposed, or with their long axes nearly vertical, 

 form a series which runs obliquely toward the perithecium, each cell pro- 

 ducing externally a single branch ; the branches either simple and mostly 

 three-celled or branched above their basal cells; the branchlets two in 

 number, mostly four-celled, their basal and terminal cells very small, all 

 the >epta somewhat dark, slightly constricted: the inner appendage con- 

 sisting of a basal cell bearing on either side a short series of cells like 

 that of the outer appendage and similarly branched, except that the three 

 or four lower branches consist of a Bingle cell bearing terminally a pair 

 of rather stout long-necked antheridia ; the three series closely apposed 

 or united. Perithecia 100 •; 30ft. Total length to tip of perithecium 

 200 235 /ij to insertion-cell 110/a; greatest width 15 /*. Appendages 

 60-75 a.
