CHITONOMYCES AND RICKIA. 13 



by seven or eight blackish horizontal parallel ridges, which extend 

 beyond the middle of the adjacent venter of the perithecium, which is 

 otherwise nearly hyaline; cell i continuing the axis of cells g and h 

 directly, erect, about twice as long as broad, distally hyaline and 

 tapering slightly, suffused below, with several blackish flat tubercular 

 patches, the blackened base of the appendage terminal. Perithecium 

 relatively long, narrow and subsigmoid ; tapering distally; the strongly 

 convex outer margin uneven, owing to slight elevations which mark 

 the jimction of the lower wall-cells; the third external wall-cell pro- 

 ducing from its base, a rather slender, very slightly curved, blunt 

 appendage, which projects upwartl at an angle of more than 45°; the 

 slender tip curved abruptly outward, and ending in a hood-like apex. 

 Spore about 20 X 1.5 /x. Perithecia 46-50 X 10 yu, the appendage 

 9-10 X 2-2.5 fi. Total length to tip of perithecium 75-80 X 16-17 /x.

This species is most nearly related to C. deniifcrus among described 

 species. It is distinguished from all other forms, however, by its 

 conspicuous transverse blackish striations on the right side. 



Chitonomyces elongatus nov. sp. 



Long, slender, of nearly the same diameter from the basal cell to the 

 base of the perithecial tip: evenly suffused with dirty yellowish or 

 amber-brown; except the basal cell which is more deeply suffused, 

 often blackened on one side and at the base, and also a deeply suffused 

 region along the anterior margin of the tip of the perithecium which 

 merges into a more or less distinct transversely mottled area extend- 

 ing half way across the tip on the right side. Basal cell rather long, 

 convex along its suffused margin, obliquely separated from cell h 

 which it overlaps on one side almost completely, and by which it is 

 overlapped for less than half its length on the opposite side; cells d 

 and e relatively long, lying side by side, similar; cell c small and over- 

 lapping the distal end, only, of cell d, for the most part on the left side; 

 cell/ very long and narrow, its base somewhat oblique and but slightly 

 overlapped by cell g, which is relatively long and narrow, slightly 

 broader distally, and hardly longer than cell h; cell i more than twice 

 as long as broad, bent against the margin of the perithecium some 

 distance below its apex. Perithecium very long and narrow, the tip 

 hardly distinguished, except by its suffusion; the apex well distin-
