210 THAXTER. 



Well developed specimens of this species are almost perfectly bi- 

 laterally symmetrical, the divergence of the paired antheridia and 

 perithecia increasing with age. The elongate distal portion of the 

 appendage is soon broken off, and persists in few even of the younger 

 specimens. The host has been kindly determined by Dr. Fenyes. 



Dichomyces Chilensis nov. sp. 



Pale yellow tinged with brown, more deeply on the right side; 

 asymmetrical through the somewhat greater de^'elopment of the tiers 

 at the right, and the greater length of the left perithecium; form 

 rather stout, with a slight curvature to the right from base to apex. 

 Basal cell large and broader than long, stained with blackish brown 

 just above the foot. Second tier consisting of four cells, including a 

 small cell separated at the right. Second tier consisting of usually 

 twelve cells, five at the left and six at the right of the median cell, the 

 paired antheridia large, conical, erect, pale brown. Third tier of 

 usually about fourteen cells, one or two more at the right than at the 

 left. Appendages rather short and unequal. Perithecia two, paired, 

 arising on either side of the median cell, tilted slightly to the right, 

 somewhat asymmetrical, uniformly pale brownish yellow, the apex 

 subhyaline, the tip darker brownish; rather long, of nearly uniform 

 diameter, slightly inflated, the tip rather clearly distinguished by its 

 color and decreasing diameter; the apex as long, broad, distally flat 

 conical, not quite symmetrical. Spores about 35 X 3.4 fx. Perithe- 

 cium 75-100 X 22-25 fx. Total length to tip of perithecia 175-220 m, 

 greatest width 50-80 ju. 



On Qvcdivs sp., more often at the tip of the abdomen, No. 1522, 

 Corral, Chile. 



This species is well distinguished by its asymmetry of form and 

 coloration, and the flat conical termination of its perithecia. Like 

 other species of the genus it varies greatly in size and the number of 

 cells in the tiers above the first is somewhat inconstant. As usual 

 individuals with single antheridia and of somewhat stouter habit may 

 occur on the legs. 



Cantharomyces Andinus nov. sj). 



General color brownish yellow, the basal cell and the stalk-cell 

 nearly hyaline. Receptacle strongly geniculate, the basal cell some- 

 what longer than broad, of nearly uniform width, the lower half, or
