to produce a small number of antheridial cells. The perithecium 

 straight, or somewhat curved outward, tapering continuously from 

 its hardly inflated base to the tip, which is but slightly distinguished, 

 nearly conical, the apex bluntly pointed, often surmounted by a short 

 apiculus; the inner wall-cells twenty-four or less, the outer usually 

 twenty-six, those below the tip slightly prominent. Perithecia 125- 

 190 X 25-50 ^t. Spores 45 X 2.5 m- Total length to tip of appendage

This species was found in considerable numbers on a single individual 

 of its host, all the others examined being quite free from it. Although 

 the perithecia are similar to those of T. brcvis, the two species illustrate 

 the extremes of development in the receptacle of this genus. There 

 is great variability in the development of different individuals, smaller 

 forms with siilgle perithecia being nearly as abundant as those in 

 which several are produced. 



Tettigomyces Indicus nov. sp. 



Receptacle variably elongated about the same diameter throughout 

 or somewhat broader below the perithecia, consisting of sixty or fewer 

 cells superposed in a simple series; the cells much flattened and 

 irregular. Appendage continuous with the receptacle, not distin- 

 guished from it, greatly elongated, simple, divergent, distally flexed 

 inward, tapering; consisting of about eighty or less superposed cells. 

 Perithecia one to several arising at intervals from the receptacle; 

 usually solitary, rather stout and short, the body hardly narrower 

 distally, but very abruptly distinguished from the tip, to the base of 

 which its outline bends almost at right angles; the tip short and more 

 or less pointed ; the outer and inner rows of wall-cells having seventeen 

 and fifteen cells respectively, those immediately below the base of the 

 tip becoming prominently rounded outward, the lower cells of the 

 inner row not at all prominent and having half, or less than half the 

 transverse diameter of the corresponding cells of the outer row.
