Dichornyces dubius nor. sp. 



Receptacle mucb a~ in D. princeps and similarly colored, smaller, 

 Bhorter, and stouter, antheridia large purplish ; the distal tier of cells 

 producing typically tun, rarely more, perithecia, which hit pale brown- 

 ish and dimorphous; usually rather Blender, tapering slightly, tin- pos- 

 terior lip-cella producing car-like outgrowths recurved or bent forward 

 a> in 1). vulgatus: more rarely Larger and Btouter, the blunt, often asym- 

 metrical t i | » without appendages; the two tonus sometimes, but not 

 usually, associated on the same individual : external appendages normally 

 large, long, colorless, reaching to the middle of the perithecium or even 

 to its tip. Individuals asymmetrical, with a Bingle antheridium and peri- 

 thecia of the second type, are not infrequently met with on the legs of the 

 host. Perithecia 70-90 X 2<>//., those without appendages 70—105 X 30 

 -35 ft. Spores. - ;.", x l/i. Receptacle about 120 x 7.3 ft. Total length

On PkilonthllS sp., Niagara Falls. New York. On all parts of host, 

 On hosts received from .Mr. Charles Bullard. Possibly a variety of />. 

 princeps, to which it is very closely allied. None of the abundant mi 

 rial of the latter from differ* nl parts of the world, however, show any 

 tendency to produce an auricled type of perithecium. 



Dichornyces Peruvianus nov. sp. 



Receptacle with faint brownish shades especially along the septa, 

 almost in the form of two superposed isosceles triangles, the lower \. ir- 

 regular, including the basal cell and the first and second tiers, its distal 

 margin horizontal, the upper truncate at the base and distally concave. 

 The basal cell short, the lower tier consisting of from three to torn- cells, 

 marly equal in length; the middle tier of typically thirteen cells, 

 antheridia of medium size, the outer five cells distally appendiculate, 

 of the appendages situated behind the antheridium as usual; the distal 

 series consisting of usua'ly twenty-seven cells hearing typically lour peri- 

 thecia, the appendages placed as usual, colorless, somewhat shorter than 

 the perithecia, which are mostly brownish externally and hyaline on the 

 inner side, the brown or reddish fawn color sometimes predominating. 

 asymmetrical, somewhat inflated, slightly bent inward near the tip which 

 b small, pointed, and well distinguished. Perithecia about 120 30 fi. 

 Receptacle 207-240 X 1-10-17.")//. Appendages 185 p. (longest). Total 

 length to tip of perithecium 300-350 //.
