amber brown, the lower half or third often abruptly lighter, tapering to a 

 blunt tip which bears on either side a short, stout, often slightly recurved 

 ear-like outgrowth as in D. furciferus formed by the prolongation of the 

 anterior lip-cells, the posterior lips forming a usually angular, sometimes 

 sharply {)ointed projection between them. Antheridia purplish, nearly 

 straight or slightly curved, rather abruptly enlarged below the sharply 

 pointed apex, the venter somewhat inflated. Perithecia 80-1 00 X 25 /x. 

 Antheridia 35 X 7 /x. Total length to tip of perithecia 200-225 X 100 

 -115 /x. Appendages 35 /A.

Dichomyces Cafianus nov. sp. 



Tinged with dull amber brownish throughout, the perithecia darker. 

 Basal cell nearly hyaline, the lower tier as in D. vidgatus, the opacity 

 involving in general but half of the upper (external) cells, the septa of 

 which are visible on the inner side, the median cell dark brown, its lower 

 half or more opaque : the middle tier consisting of typically thirteen cells, 

 the margins unmodified and ending in a short external rounded projection, 

 which does not extend beyond the base of the upper tier; the rather in- 

 conspicuous antheridium normally placed, concolorous, a single short 

 appendage close behind it : the upper tier consisting of from nineteen 

 to twenty-three, usually twenty-one, cells, forming an inverted crescent, 

 the short, stout, bladder-like appendages arranged as in D. vidgatus. 

 Perithecia normally two in number, somewhat inflated externally, nearly 

 straight, slightly asymmetrical, rather stout, tapering to the bluntly 

 pointed undifferentiated tip. Spores 45 X 4.5 /x. Perithecia 120-140 

 X 35-40/;.. Receptacle 200-250 X 100-140 /x. Total length to tip of 

 perithecium 310-350 /u. Appendages about 20 X 6/x.
