THAXTER. — iNEW LABOULBENIACE^. 183 



Laboulbenia leucophaea nov. sp. 



Perithecium dark brown, almost opaijue, rather small, hardly more 

 thau the tip free from the receptacle ; the tip relatively large and long, 

 bent slightly outward, not abruptly differentiated, black except around 

 the pore, the right inner lip forming a hyaline nearly median blunt out- 

 growth which is bent slightly outward. Receptacle sometimes twisted at 

 the distal end of and above cell II j cell I hyaline; cell II suffused with 

 brown, in some cases with deeper brown tranverse elevations on one 

 side ; the lower half of cell III and cell VI hyaline, the rest of the 

 receptacle concolorous with the perithecium. The outer appendage 

 simple, its basal cell four or more times as long as broad, curved toward 

 the perithecium ; the basal cell of the inner appendage very small, 

 bearing in general a single short branch, both appendages pale yellowish. 

 Perithecium to tip of outgrowth 130-150 X 35-40 ju. Total length to 

 tip of perithecium 325-375 /x ; to insertion-cell 250-290 /a ; greatest 

 width 55-65 ^. Appendages about 200 jjl.

Laboulbenia Loxandri nov. sp. 



Perithecium about three fourths free, suffused with brownish, translu- 

 cent, the distal half narrow and strongly curved inward, especially at the 

 tip, the latter externally and distally blackened, the lip-edges hyaline. 

 Receptacle rather stout, pale dirty brownish ; cell II basally and distally 

 and cell VI externally more deeply suffused. Cells IV and V elongated 

 so that they become parallel and carry the insertion-cell upward and out- 

 ward free from the perithecium. Outer appendage consisting of a 

 rounded basal cell bearing a single terminal branch, the basal cell and 

 one or two cells above it rounded, constricted at the mostly blackened 

 septa, simple or each of the lower cells producing distally on the inner 

 side a branchlet, the branchlets and the terminal portion of the main 

 branch hyaline, slender, thin-walled, tapering. Inner appendage con- 

 sisting of a basal cell like the outer and like it producing a branch on 

 either side. Spores about 45 X 4 ^. Perithecium 140 X 40 /i. Total 

 length to tip of perithecium 340 /x ; to insertion-cell 275 fi. Appendages, 

 longest 120^.
