This peculiar species is most nearly ailed to C. obtutms which it 

 resembles in general habit and coloring. It is clearly distinguished 

 by the peculiar conformation at the apex of its peritheciura. 



Stichomyces Pterogenii nov. sp. 



Foot relatively large; receptacle sulKlecvunbent, broadest at the 

 base when seen sidewise; colorless or faintly yellowish, continuous 

 with the primary appendage from which it is in no way distinguished, 

 the whole consisting of about six superposed cells; the four lower 

 somewhat larger, rather irregular in size, somewhat broader than 

 long; the second, third and fourth giving rise laterally either to single 

 perithecia, or to single short branches; the subbasal cell more often 

 producing a short antheridial branch, and the cell above it an up- 

 curved perithecium; the terminal cells of the axis giving rise on one 

 or both sides to rather slender, elongate, tapering branches, which are 

 simple or once l)ranched near the base, turned upward parallel to the 

 perithecium. Perithecium rather slender and long, borne laterally 

 on a short stalk-cell which is bent abruptly upward; the venter 

 somewhat broader, tapering slightly to the hardly differentiated tip, 

 which is short, often slightly bent, tapering to a blunt point. Peri- 

 thecia 40-50 X 9-12 jjL. Spores 18-20 X 2 /x in perithecium. Main 

 axis 30-35 X 10- 12 jj. at base. Longest branches 175 ijl.

This rather nondescript form is somewhat doubtfully referred ta 

 the genus SticJiomyccs, of which it may be an aberrant and reduced 

 type. The tendency to produce branches and perithecia on either 

 side of the main axis, and the common occurrence of a branch below 

 the perithecium from the subbasal cell would make it difficult to in- 

 clude it in Corethromyces which it resembles in some respects, nor does 

 it seem possible to include it in the genus Chactomyces, although the 

 position of this last genus is somewhat uncertain. The perithecium,. 

 which is normally single, is more often produced by the third cell. 

 The axis lies nearly parallel to the surface of the host, and the peri- 

 thecium and long slender branches, at the bases of which short antheri- 

 dial branchlets may arise, are abruptly bent upward. 



Stichomyces Cybocephali nov. sp. 



Very constantly coherent in pairs; straight, nearly colorless, the 

 foot relatively very large, the axis consisting of from six to eight
