points on either side of the receptacle. Total length to tip of perithe- 

 cium 280-300 /x. Perithecium 90-100 (i X 22-29 /*. Spores fusiform, 

 asymmetrically once septate, involved in mucus, 26 X 4 /i. Pseudo- 

 paraphyses sometimes 60 ^ in length. 



Host, Platynus cincticollis. Connecticut. 



This genus appears to differ from other known genera in the pres- 

 ence of several groups of paraphyses on both sides of the receptacle. 

 The presence of two perithecia was only observed in a single speci- 

 men. The perithecium resembles that of Helminthophana in being 

 symmetrical at the apex. The genus is named in memory of the late 

 Dr. Peyritsch, as a slight recognition of his well known and admirable 

 work upon this family. 



CANTHAROMYCES nov. gen. 



Receptacle simple ; or compound above the supra-basal cell, from 

 which one or more divisions may arise, each bearing a solitary perithe- 

 cium. Pseudoparaphyses, one or more, arising from the supra-basal 

 cell. Perithecium median, tapering towards its symmetrical apex. 



Cantharomyces verticillata nov. sp. 



Color paie yellowish. Perithecium expanding slightly above its 

 base, then tapering slowly towards its slightly truncate, conical apex. 

 Pseudoparaphyses arising in a whorl of two to four (the number ap- 

 parently variable) from the small supra-basal cell; simple or branched ; 

 once or twice constricted at the septae ; the joints short, stout, and 

 broader towards their rounded apices. A single simple pseudopara- 

 physis composed of cylindrical segments hardly constricted at the 

 8epta3 arises also from the distal end of the third stem cell. Recep- 

 tacle simple, composed of five single superposed cells, arising from a 

 small black piece of attachment, the first four nearly cylindrical, the 

 fifth short, slightly expanded towards the base of the perithecium, 

 which is made up of two or three very small cells. The snpra-basal 

 cell is squarish about half the length of the basal. The third and 

 fourth cells are nearly similar, somewhat longer than the basal and 

 supra-basal taken together. Spores fusiform, apparently once septate, 

 and about 18-20 /x X 3 /x (these were only examined, however, loithin 

 the perithecium). Perithecia 90-1 27 /x X 18-26 /x. Pseudoparaphyses 

 50-125 /x. Receptacle 75-125 yu, X 11 /x.
