Eucantharomyces Diaphori dot. sp. 



Pah' Btraw colored. Perithecium rather short and stout, its basal cella 

 ill, slightly and usually symmetrically inflated; tapering from about 

 the middle to the broad blunt Blightly asymmetrical tip, which ia Bub- 

 t- nihil liflow the free lips, on the inner Bide, by the Bat trichophoric 

 cell, jusl above which arises a very Blender recurved rigid append 

 (not cellular) about 8-9 /i long. Receptacle rather short ami Btout, the 

 Bubba8a] (anterior) cell somewhat stouter than the basal, the two together 

 somewhat larger than the short stalk-cell of the perithecium. Appen- 

 dage relatively large, its basal cell short suhtriangular, the upper ami 

 low ei- septa oblique, the subbasal cell Blightly longer than broad, its upper 

 two thirds bordered by the marginal cell which terminates in a -lender 

 stiff straight Bpine-like process about 11-12/;. long ;m ,i slightly diver 

 gent; the antheridial cell- in five rows of five, tour, three, three, and two 

 cells respectively ; a single additional cell sometime- persisting above the 

 antheridial cavity; the discharge tube bent outward and Blightly upward, 

 the tip bluntly coincal with a slight basal enlargement. Spores 10 X 



3.5/*. Perithecia 120 X 30/1. The stalk-cell 30 X 18/». Appendage 

 70fi long, the antheridium 28 X 21//. Receptacle 45 X 24 fi. Total

 No. 71 1. Oaxaca, Mexico. On mid-elytron. 



Eucantharomyces spinosus nov. sp. 



Perithecium straw colored, rather stout, inflated, tapering to the broad 

 asymmetrical tip which is slightly silicate; the outer lips often larger 

 than the inner, the latter bordered or subtended by the more deeply 

 Colored trichophoric cell which, in mature specimens, is not very COn- 



spicuous; the stalk cell rather short. Receptacle short, the cells nearly 

 equal. Appendage much a- in II. Diaphori, more slender, the marginal 



cell extending Dearly to the base of the subba-al cell, distinctly enlarged 

 below a terminal spine-like process, which is usually nearly erect ; the 

 antheridial cells in three rows of five, three (relatively large) and one to 

 two cell- respectively, the discharge tube large and broad, nearly trun- 

 cate, bent abruptly upward from the base. Spores 35-40 X 8.5-4 /x, 

 Perithecia L88 • 11/'. Appendage 70 ■ 1 1 /», the antheridium 85 X
