Stigmatomyces Hydrelliae now sp. 



V. -liter of the perithecium umber brown, oval, the wall-cells becoming 

 separated by well-defined, slightly oblique longitudinal broad ridges, 

 which become broader distally where they end abruptly; the neck pale, 

 well distinguished, its middle third prominently inflated, more so poste- 

 riorly, ami separated from the usually abruptly bent tip by a constric- 

 tion ; the apex rounded, one of the (lateral?; lip-cells forming a slender, 

 bluntly pointed, well-defined free projection. Stalk-cell of the appendage 

 sub-triangular, somewhat prominent below the basal cell, which nearly 

 equals it in length, sterile ; tin- fertile cells above it nearly equal, bearing 

 rather large, apparently single, antheridia, with stout, straight necks, the 

 series ending in a terminal .--piniferous antheridium. Receptacle hyaline, 

 the two cells Dearly equal in length, the lower tapering below, the upper 

 broader inflated, its diameter greater than the base of the perithecium 

 ami stalk-cell combined, bo that the latter region appears to be con- 

 Btricted. Spores 28 • _//. Perithecium : venter 50— 55 X 33-40 /& ; neck 

 40— 43 /a. Appendage .j<»/x, the stalk-cell 18 ft. Receptacle 55-G5 X 

 I'U-L'^u. Total length to tip of perithecium 150— 185 /x. 



On the superior surface of tin- abdomen, sometimes on the legs of 

 HydreUia sp. Kittery Point. Maine. Occurring in scattered groups. 



Stigmatomyces purpureus nov. sp. 



Hemming wholly Buflused with purple. Venter of the perithecium 

 inflated toward the base, tapering distally ; the four wall-cells separated 

 by a corresponding number of prominent longitudinal ridges, rounded in 

 ■ hi, which run spirally, making in well-developed individuals a whole 

 half turn about tin- venter, and becoming sometimes lobulated through 

 tin- presence of successive constrictions and enlargements ; neck not 

 abruptly distinguished, except by the abrupt elevations which form the 

 terminations of the longitudinal ridges of the venter, rather Blender, an 

 abrupt posterior subterminal elevation preceded bj a slight constriction, 

 the tip distally quite hyaline ] the apex becoming furcate through the 

 presence of an anterior (shorter) and a posterior projection. Stalk-cell 



of the appendage relatively small, but sliglnh prominent below the basal 



Cell, which ifl nearly as long, Sterile, and, as a rule, followed bv three 

 cells hearing antheridia singly or in pair-, the terminal one Bpiniferous. 



1; eptaele usually straight, the cells nearly equal or the upper larger.
