which is bent slightly upward. Receptacle more or less suffused, some- 

 times deeply colored with blackish brown, cells I and II paler, slender, 

 of nearly equal width, cell II longer ; cells IV and V very broad, carrying 

 out the insertion-cell free from the receptacle so that it becomes oblique 

 or even vertical and lateral. Outer and inner appendages similar, bent 

 away from the perithecium, their bases overlapping ; consisting of a series 

 of superposed cells which are sucessively smaller from below up, each 

 bearing distally and externally a short tapering branch ; all the branches 

 brown, the subbasal septa blackened, all simple except the lower branch 

 of the outer appendage which bears two to three short branchlets ; the 

 basal cell of the inner appendage bears a short antheridial branch from 

 its inner side ; the outer appendage somewhat longer than the inner, the 

 superposed cells usually eight in number. Perithecia 140-100 X 40-45 ^. 

 Total length to tip of perithecium 400-550 /a ; to insertion-cell 270- 

 450 fx. Appendages, 140-170 fx. Tip of perithecium, including out- 

 growth, 50-60 /A.

 on Brachinus sp., Eustis, Florida, October. At base of anterior legs. 



Laboulbenia separata nov. sp. 



Perithecium pale olivaceous, the inner margin convex, the outer nearly 

 straight; the tip rather abruptly distinguished, blackened, but not uni- 

 formly, below the inner lip-edges, prominent olivaceous translucent, the 

 right inner lip prolonged to form a slender nearly hyaline projection, the 

 tip of which is blunt and somewhat swollen. Receptacle dull olivaceous, 

 cells II, III, and IV sometimes becoming blackish brown externally, 

 cells III and IV rather large ; the insertion-cell close to the base of the 

 perithecium, half as broad as cells IV and V. Appendages much as in 

 L.jissa^ the outer curved strongly outward, opaque and indistinguishable 

 from the insertion-eel], bearing three or four branches from its convex 

 side which are mostly once branched (the outer appendage usually 

 broken) ; the inner appendage consisting of a small basal cell, bearing a 

 branch on either side externally blackened, somewhat curved outward, 

 and bearing three or four branchlets which are curved toward the peri- 

 thecium, externally or wholly brownish toward the base. Perithecia 

 100-110 X 25-30 iJL. Total length to tip of perithecium 220-260/^ ; to 

 insertion-cell 130-165 fx. ; greatest width 55 /x. The prolongation of the 

 lip-cell extending about 20 [i or more beyond the tip of the perithecium.
