Cantharomyces Chilensis nov. sp. 



Unevenly tinged ^^^th dark smoky brown, the basal cell and the 

 stalk of perithecium paler. Receptacle somewhat geniculate, short, 

 the basal cell darker above, its posterior wall somewhat blackened in 

 connection with the foot, broader distally; subbasal cell mostly some- 

 what shorter, subtriangular, the walls, especially the posterior, very 

 dark blackish brown. Appendage short and very broad, its outer 

 walls very dark blackish brown, the stalk-cell usually broader than 

 long, its inner upper angle rather conspicuously blackened; the 

 antheridial segment usually slightly larger and somewhat convex on 

 either side, somewhat oblique above and below, the outer margin 

 shorter, the antheridial region usualh'' on the right; the rest of the 

 appendage consisting of a very broad flat dark cell, lying almost 

 opposite the base of the ascigerous region, sometimes followed by a 

 seconfl smaller one; the cell above dividing several times vertically 

 or obliquely, its divisions proliferating to form an irregular group of 

 short, simple, stout, hyaline branches of variable length and diverg- 

 ence, sometimes ten or more in numl^er. Perithecium and its stalk 

 similar to that of C. And'mus, the basal cells about equal, darker than 

 the pale stalk, but lighter than the dark smoky brown body ; which is 

 subtended on either side by more deeply blackened areas of the wall; 

 the apex nearly hyaline. Spores about 28 X 3.5 ix. Perithecium 

 average 70 X 30yLi: the stalk- and basal cell region 35—42 X 20 /x. 

 Appendage, to tips of branchlets, longest, about 65 jx, the axis, in- 

 cluding stalk-cell, 35-12 X IS jjl. Receptacle, including foot, 32 X 

 20 n. Total length to tip of perithecium 110-130 ^i. 



In various positions on Trogophlorus sp.. No. 1474, Banos de Apo- 

 quindo, Chile. 



This species, which is distinctly larger than the last, although it is 

 closely allied to it, differs in the absence of any contrasting blackening 

 of the subbasal cell, in its general dark smoky brown color and espe- 

 cially in the characters of its very broad appendage. 



Cantharomyces Valdivianus nov. sp. 



Basal cell of the receptacle bent, sometimes at right angles to the 

 subbasal, of nearly uniform width, nearly hyaline or faintly brownish, 

 distally involved by the opaque sufl'usion of the subbasal coll, the upper 

 somewhat oblique margin of which, and a small portion of the anterior
