Basal cell relatively large, somewhat longer than broad, deeply 

 suffused with brown; the subbasal cell smaller and obliquely divided 

 into two cells, the upper of which forms the basal cell of the primary 

 appendage and is distally prominent externally, its margin bending 

 abruptly inward to the insertion of the free appendage, which is 

 composed of eight or more flattened cells, separated by constrictions 

 and blackish septa, two to four of the distal ones bearing short up- 

 curved or rigid slightly divergent branchlets. Secondary receptacles 

 more or less involved in the browTi suffusion of the receptacle, their 

 closely crowded cells forming with it a compact body, somewhat 

 triangular in outline, which may be as a whole nearlx- opaque, the 

 exact origins of the numerous branches and of the perithecia, several 

 of which may mature, is hardly determinable; the bases of the second- 

 ary receptacles overlapping the basal cell somewhat and deeply 

 blackened; the branches similar to the primary appendage above its 

 basal cell, some terminating in an antheridium or bearmg one or more 

 short antheridial branches in addition to sterile ones. Perithecia 

 bent more or less abruptly backward above the short hyaline portion 

 of the stalk, the insertion of which is black, and which is succeeded by 

 an opaque area that broadens distally and involves the secondary 

 stalk-cell and the basal cell region, except its upper inner angle, and 

 extends obliquely beyond the base of the perithecium. The latter 

 slender, subcylindrical, or slightly inflated below, and tapering slightly 

 to the extremity; the venter and neck regions not distinguished, and 

 marked by more or less regular transverse purplish bands, which 

 separate corresponding hyaline ridges that arc variably evident; 

 the tip long, clearly differentiated, often slightly inflated, purplish, 

 tapering slightly to the very short apex which is bluntly rounded or
