Eucantharomyces Callidae nov. sp. 



Perithecium rather narrow, slightly inflated, tapering from about the 

 middle to the blunt tip which is rather abruptly distinguished externally, 

 sometimes bent outward, its distal margin outwardly oblique; the rela- 

 tively small trichophoric cell simulating a lip-cell, projecting slightly be- 

 yond the latter externally, but not abruptly distinguished on its inner 

 side ; the outline of the perithecium becoming inconspicuously corrugated 

 through the presence of sometimes as many as eleven successive eleva- 

 tions ; the basal cells elongated, the base of one of the outer external to 

 the stalk-cell from which it is separated by an oblique septum longer 

 than the width of the stalk-cell, which is narrower below and about equal 

 to the basal cells in length or somewhat shorter. Receptacle symmetri- 

 cally sulcate distally, rather long, the two cells nearly equal. Appen- 

 dage rather long, its basal cell extending downward and lying external 

 to the upper half of the subbasal cell of the receptacle ; the subbasal cell 

 more than twice as long as broad, the marginal cell reaching to its base 

 and distally prominent. Antheridium relatively small, the antheridial 

 cells in three rows of five, four, and three cells respectively, the discharge- 

 tube rather short and stout, erect or bent but slightly. Spores 40 X 4/x.

On Callida sp., Paris Museum, No. 68. Venezuela. 



Eucantharomyces Africanus nov. sp. 



Very similar to E. CnlUdfB. Amber brown. Perithecium large sub- 

 fusiform, the margins generally indistinctly corrugated, sometimes marked 

 by fine transverse striations which may be wholly absent, the tip rela- 

 tively small and rather abruptly distinguished, the trichophoric cell well 

 defined, projecting beyond the lip-cells so that the apex usually appears 

 oblique asymmetrical and slightly sulcate ; the basal cells somewhat
