Laboulbenia maculata nov. sp. 



Perithecium free, dark brown becoming nearly opaque, the outer 

 margin more convex than the inner ; somewhat constricted at the base, 

 the tip rather abruptly distinguished externally, the margins nearly 

 straight, the inner lips small and prominent, the outer broad, straight, 

 oblique. Receptacle abnormal, cell I short, slender, curved, opaque ; cell 



II nearly hyaline in the middle, brownish above, coarsely spotted with 

 blackish brown below, becoming darker and indistinguishable from cell 

 I at its base ; cell VI distally nearly hyaline and narrow, extending 

 down beside cell II nearly if not quite to cell I, its base spotted as in cell 

 II ; cell VII (the " secondary stalk-cell ") external to it, the margin 

 blackish brown especially distally, extending down beside cell VI to 

 within a short distance of its base where it is similarly punctate 

 towards its base or throughout ; cell III narrow, external to the upper 

 two thirds of cell II, punctate below, its distal end close beside the cor- 

 responding termination of cell II ; the base of cell IV overlapping cell 



III so that a cross section in this region would cut cells II, III, IV, 

 VI, and VII : distal portion of the receptacle concolorous with the 

 perithecium or somewhat paler. The perithecium bent toward and 

 partly or wholly overlapping the insertion-cell. Appendages directed 

 across the lower half of the perithecium sometimes at right angles ; 

 consisting of a large outer basal cell sometimes slightly inflated, bearing 

 distally one or usually two antero-jjosterior simple branches which are 

 slender, rather rigid, their diameter much less than that of the basal cell : 

 the inner appendage consisting of a smaller basal cell which may pro- 

 duce one or two branches similar to those of the outer appendage ; all 

 the branches slender, rather rigid and straight, parallel and closely ap- 

 proximated, tapering but slightly. Perithecia 225 x 60 /x. Total length 

 to tip of perithecium 560 /x ; to insertion-cell 375 /x; greatest width 140/x. 

 Appendages about 200-250 /x.

Laboulbenia Madagascarensis nov. sp. 



Perithecium free, mostly straight, the inner margin more convex, uni- 

 formly clear dark brown or blackish except just below the black tip, 

 abruptly distinguished from and contrasting with the receptacle ; the tip 

 rather abruptly distinguished, straight or bent slightly inward, with 

 hyaline lip-margins, the wall-cells with a slight spiral turn. Receptacle
