as the receptacle, becoming pale amber brown, tapering to a pointed 

 apex. Perithecium becoming pale amber brown, relatively large, thick 

 walled, considerably and abruptly inflated above the basal cells, somewhat 

 asymmetrical, tapering rather evenly to the blunt apex ; the stalk-cell 

 long, thick walled, slightly curved, nearly hyaline, distally somewhat 

 broader, not distinguished from the basal cells. Spores about 40-45 

 X3.5ja. Perithecia 180-200 X 72-82 /^ ; the stalk-cell 110-120 X 

 28-30 /A. Antheridium including the stalk-cell 55-65 /j.. Total length 

 to tip of perithecium 360 /a.

Eucantharomyces Xanthophaeae nov. sp. 



Perithecium (not fully mature) straw colored, somewhat asymmetrical, 

 almost symmetrically and but slightly inflated from base to apex; the 

 tip short, well distinguished ; the lip-cells rounded, and slightly inflated, 

 forming a knob-like termination, one of them protruding in the form of 

 a slight tongue-like projection beyond the others : the stalk-cell about 

 as long as the receptacle, from which it projects at an angle, being more- 

 over turned at the same time a little to one side. The cells of the recep- 

 tacle subequal, lying side by side, the basal one extending to the base of 

 the stalk-cell of the perithecium, with which it is in contact. Appendage 

 relatively large, the stalk-cell subtriangular, somewhat larger than the 

 basal cell which is wholly overlapped externally by the well defined and 

 distally somewhat inflated marginal cell; the antheridial cells in four 

 tiers of seven, six, five and four cells respectively ; the discharge-tube 

 long and curved outward. Spores about 36 X 4 /a. Perithecia 165 X 

 50 II, the stalk-cell 46 X 20 yu,. The appendage to tip of discharge tube 

 120 /x, the antheridium proper 55 X 30 /x. Total length to tip of peri- 

 thecium 290 |U.

Dichomyces bifidus nov. sp. 



Basal cell slightly enlarged, pellucid, tinged with brown, about as long 

 as broad : the lower tier, and more or less of the middle tier, opaque ; 

 the marginal cells of the latter forming a bluntly rounded, sometimes 

 almost obsolete projection on either side, hardly extending above the
