cell bordering its upper half and distally promineBt, partly free and slightly inflated, ending in a short 

 spine-like tip; the antheridium consisting of three rows of nine, seven and five cells respectively, the dis- 

 charge-tube relatively short and stout, bent upward and over the prominent tip of the marginal cell.

Allied to C. Africanus which it resembles in general form, but from which it is at once distinguished 

 by the characters of the appendage.

Straw-colored becoming pale amber-brown. Perithecium elongate, tapering but slightly toward 

 the tip, or becoming distally swollen through the pressure of the spore mass, the margins corrugated 

 through the presence of sometimes as many as seventeen or even more prominences, which are mostly 

 well defined, especially the distal one of the series and often distinctly rough-granular, above which the 

 slightly bent tip is abruptly distinguished, its distal margin straight oblique, the outer and lateral lip- 

 cells extending just beyond the small darker inner lip-cell; basal-cells very much elongated and often 

 corrugated through the presence of six or more elevations; the stalk-cell rather stout, much shorter than 

 the basal cells, from which it is separated by an outer very oblique, and an inner short nearly horizontal 

 septum. Receptacle relatively small, the basal cell longer than the subbasal cell, distally enlarged so 

 (hat it almost coincides with the base of the stalk-cell, which is thus hardly in contact with the subbasal 

 cell from which it was originally derived. The basal cell of the appendage somewhat smaller than the 

 subbasal cell, the marginal cell bulging outward slightly distally, and extending almost to the base of the 

 subbasal cell. Antheridial cells in five rows of eight, seven, six, five, and four cells, or the four inner 

 rows somewhat variable. Spores 50 X 4.5 p. Perithecia 400-475 X 60-70 p, the stalk-cell 140-200 X 

 35-40 p, the basal cells 200-240 p. Receptacle 100-110 X 38 p. Appendage 120 p; antheridium 60 X 

 32 p. Total length 680-950 p.

The largest and most striking species of the genus, the corrugated elevations of the perithecium, al- 

 though sometimes partly obliterated by the copious spore formation, serving to distinguish it, apart from 

 its other peculiarities. The aseogenic cells are remarkable from their subclavate form, at least eight 

 being arranged in a rosette, as is indicated in fig. 13.

Pale straw-colored. Perithecium rather short and stout, its basal cells small, slightly and usually 

 symmetrically inflated; tapering slightly from about the middle to the broad blunt slightly asymmetrical 

 tip, the flat inner lip-cell, small, lateral, and subterminal, bearing distally a slender recurved rigid append- 

 age (not cellular) about 8-9 p long. Receptacle rather short and stout, the subbasal (anterior) cell some- 

 what stouter than the basal, the two together somewhat larger than the short stalk-cell of the perithecium. 

 Appendage relatively large, its basal cell short subtriangular, the upper and lower septa oblique, the 

 subbasal cell slightly longer than broad, its upper two thirds bordered by the marginal cell which ter- 

 minates in a slender stiff straight spine-like process about 11-12 p long and slightly divergent; the 

 antheridial cells in five rows of five, four, three, three, and two cells respectively; a single additional 

 cell sometimes persisting above the antheridial cavity; the discharge tube bent outward and slightly up- 

 ward, the tip bluntly conical with a slight basal enlargement. Spores 40 X 3.5 p. Perithecia 120 X 30 p. 

 stalk-cell 30 X 18 p. Appendage 70 p long, the antheridium 28 X 21 p. Receptacle 45 X 24 p. Total 

 length to tip of perithecium 180 p.
