On Drypta sp., Paris Museum, No. 80. Java. On elytron. 



Eucantharomyces Euprocti nov. sp. 



Perithecium straw colored to pale amber brown, slightly asymmetrical, 

 somewhat inflated below ; the upper half tapering gradually to the blunt 

 asymmetrical apex which is subtended on the inner side by the rounded 

 flat darker amber brownish trichophoric cell which may extend slightly 

 beyond the lip-edges, simulating a lip-cell ; the outline of the mature 

 perithecium becoming more or less corrugated through the appearance of 

 three to five rather broadly rounded successive elevations, corresponding 

 to the distal and basal septa of the two lower tiers of wall cells and to 

 a median protrusion of these cells where five are present; stalk-cell be- 

 coming slender, mostly slightly shorter than the receptacle ; the basal 

 cells small. Receptacle relatively rather long, the cells nearly equal. 

 Appendage generally longer than the receptacle, its basal and subbasal 

 cells nearly equal ; antheridial cells in three rows of five, three, and two 

 cells each, the marginal cell bluntly rounded above and extending nearly 

 to the base of the subbasal cell ; the discharge-tube large, bent outward 

 or obliquely upward. Spores 50 X 4.5 fx. Perithecia 160-170 X 48 //., 

 stalk-cell 70 X 15 /x. Receptacle 85-90 X 25-30 /x. Appendage 110/*, 

 antheridium 41 X 22 /x, the discharge-tube 30 /x. Total length to tip of 

 perithecium 310 fx.

Eucantharomyces Casnoniae nov. sp. 



Perithecium relatively large, rather long, often slender, inflated below, 

 tapering to the relatively narrow blunt apex; its outline corrugated 

 through the presence of from seven to eleven elevations varying in 

 prominence, the trichophoric cell simulating a lip-cell, the basal cells 

 elongated and as long or nearly as long as the rather stout stalk-cell. 

 Receptacle relatively small. The basal and subbasal cells of the appen- 

 dage relatively small and stout, nearly equal, or the latter somewhat 

 smaller, the marginal cell bordering its upper half and dis tally promi- 

 nent, 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 discharge-tube relatively short and stout, bent upward
