half as large, bearing a branch like the outer appendage on either side : 

 all the branches erect, closely associated, and often bent terminally across 

 the tip of the perithecium which they scarcely exceed. Perithecia, aver-

 insertion-cell 145-150 ^; greatest width 48-50 fi. Appendages 30 /z.

Laboulbenia fissa nov. sp. 



Perithecium three fourths or more free, short and stout, slightly bent 

 toward the appendages, dirty olive-brown becoming deeply suffused with 

 blackish brown except distally just below the tip, which is abruptly dis- 

 tinguished, long, narrow, hyaline below its black distal portion, furcate, 

 the inner fork formed by the upgrowth of one of the inner (right) lip- 

 cells which grows outward and abruptly upward beside the deep black 

 blunt-tipped projection formed by the other three which it may equal in 

 length, though narrower and somewhat paler. Receptacle short, the 

 basal cell largest, pale yellowish or hyaline, of about the same diameter 

 throughout, broader than cell II, which is short, narrow, of equal diameter 

 throughout, hyaline or yellowish at the very base, the rest opaque and 

 indistinguishable from the remainder of the receptacle, which expands 

 abruptly above, becoming opaque except the upper part of cell IV and 

 cell V. Insertion-cell much narrower than cells IV- V. Outer append- 

 age consisting of several superposed cells, which form a black opaque 

 axis, usually broken off, curved outward, each cell producing a short hya- 

 line or brown edged branchlet distally on the inner side ; the inner ap- 

 pendage consists of a smaller basal cell, which gives rise on either side to 

 a branch much like the outer appendage, its main axis less deeply black- 

 ened, curving outward on either side of the perithecium, the hyaline 

 branchlets arising from its convex side mostly once branched. Perithe- 

 cia, average 150 X 48^, including the tip, which is about 45 X 18-20/*. 

 Total length to tip of perithecium 290-300 /* ; to insertion-cell 185 fi ; 

 greatest width 70 p. Appendages about 110^.
