differing greatly from the siibbasal in length, sometimes considerably 

 longer, tapering continuously to its narrow base and pointed foot, 

 becoming somewhat suffused with the walls greatly thickened by 

 secondary layers, so that the lumen of the lower half may be nearly 

 obliterated; distally slightly rounded or inflated, usually slightly or 

 distinctly broader than the often Inaline subbasal cell, which is nar- 

 rower below, the margins straight or slightly concave. Stalk-cell of 

 the appendage more deeply suffused, relatively short, the upper half 

 broad, its outer wall greatly thickened, the distal margin broad and 

 rounded and half or more free outside the very narrow insertion of the 

 usually deciduous appendage. Appendage curved, broad in the 

 middle and tapering to its base and apex; the axis consisting of three 

 cells; the antheridia eight in number, sometimes less, turned sidewise 

 or outward; with rather stout, prominent, slightly curved necks; 

 the basal cell short, broad and pointed above, tapering to its narrow 

 hyaline base which is separated from the \'ery narrow insertion by a 

 slight constriction; the three antheridia associated with it superposed 

 and borne on a distinct small androphorous cell, which is separated 

 from it externally; the subbasal cell bearing two antheridia which 

 diverge more or less right and left; while the third bears one, followed 

 by one or by two, superposed and terminal. Stalk-cell and secondary 

 stalk-cell of the perithecium overlapping laterally, more or less similar, 

 or the former larger; the basal cells similar, the external margins 

 slightly convex and more or less conspicuously thickened ; all the cells 

 of this region suffused, and concolorous with the stalk-cell of the 

 appendage and the, venter of the perithecium; which is relatively 

 rather short and stout, usually slightly shorter or hardly longer than 

 the distal portion from which it is abruptly distinguished by well 

 marked distal prominences corresponding to the terminations of its 

 wall-cells; the neck paler, its margins straight or slightly concave, its 

 base and apex abruptly spreading; distinguished from the stout, 

 slightly tapering tip and apex by an abrupt and conspicuous inflation; 

 the apex shorter than the tip, its blunt, often asymmetrically rounded 

 termination at length subtended by a minute papilla on either side.
