EUCANTHAROMYCES, nov. gen. 



Receptacle consistiug of two superposed cells, giving rise on one 

 side to a free stalked perithecium, on the other to a free appendage. 

 The appendage consisting of a basal and sub-basal cell terminated 

 by a compound antheridium. The antheridium formed from numer- 

 ous small cells, obliquely superposed in three rows, bordered exter- 

 nally by a sterile cell and terminated by a cavity from which the 

 antherozoids are discharged through a short irregular finger-like 

 projection. 



EUCANTHAROMTCES AtRANI, DOV. Sp. 



Pale straw-colored. Perithecium rather long, slightly inflated, 

 tapering to a blunt apex with rounded lips, its stalk consisting of a 

 single large free basal cell surmounted by three smaller cells. Basal 

 and sub-basal cells of the receptacle long and very obliquely super- 

 posed, lying almost side by side. The appendage consisting of a 

 basal cell not wholly free, but partially connected with the stalk cell 

 of the perithecium at its base, followed by a second sub-triangular 

 cell, the oblique upper walls of which separate it on the inside from 

 the body of the antheridium proper, and on the outside from the long 

 narrow cell which forms its sterile outer margin. Antheridium sub- 

 cylindrical, with rounded apex consisting of three series of obliquely 

 superposed cells decreasing in size from below upwards, and running 

 obliquely upwards and outwards, the lower series of six cells, the 

 middle of four, and the upper of two, the three series terminating in a 

 common cavity filled with antherozoids, which are discharged through 

 a terminal irregular finger-like projection which is bent strongly out- 

 wards. Perithecium 135 x 35 jx. Length to tip of perithecium 260 fx. 

 To tip of antheridium 150 jx. 



On Atranus picbescens Dej. Virginia (T. Pergande). 



Two specimens of this perplexing form were found in company 

 with Rhachomyces lasiophorus on an example of Atranus kindly sent 

 me by Mr. Pergande. The genus is based wholly upon the pecu- 

 liar compound antheridium, which seems quite different in character 

 from that of either Cantharomyces or Camptomyces, its nearest 

 allies. 



Ceratomtces mirabilis Thaxter. 



Abundant material of this species, collected in Maine and Massa- 

 chusetts, indicates that the writer has confused two closely allied 

 forms which were at first considered merely varieties of a single
