shorter than the stalk-cell, their lower septa nearly equal and symmetri- 

 cal, hoth slightly oblique. Receptacle of medium size, the basal cell dis- 

 tally enlarged. Appendage short, the two basal cells rather small and 

 nearly equal in length, consisting of three rows of six, four, and four cells 

 respectively, the discharge-tube slightly curved, abruptly nearly erect, 

 distally somewhat narrower and conical when young, the marginal cell 

 extending nearly to the base of the subbasal cell. Perithecia 275-325 

 X 45-50 /x, the stalk-cell 100-130^, the basal cells 75-100 /x. Recep- 

 tacle 100 X 2G [x. Appendage 100 //.. Antheridium 45 X 21//, the 

 discharge tube 21 /x. Total length to tip of perithecium 575-600 /a.

Eucantharomyces Catascopi nov. sp. 



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 pres- 

 ence of sometimes as many as seventeen or even more prominences, 

 which are mostly well defined, especially the distal one of the series, 

 above which the slightly bent tip is abruptly distinguished, its distal mar- 

 gin straight oblique, the lip-cells extending just beyond the small darker 

 trichophoric cell ; basal-cells very much elongated and often corrugated 

 through the presence of six or more elevations corresponding to those 

 of the perithecial wall-cells; 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 that 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 /x. Perithecia 400-475 X 60-70 /x, the stalk-cell 140- 

 200 X 35-40 ix, the basal cells 200-240 fx. Receptacle 100-1 1 X 33 fx. 

 Appendage 120 /x ; antheridium 60 X 32 fx. Total length 680-950 t i.
