ITyaline or slightly yellowish. Perithecium becoming pale amber brown, except the tip, 
which is colorless ; more or less inflated, conical above, the apex blunt symmetrical, the stalk- 
ceil about as long as the receptacle. Eeceptacle small, the basal cell somewhat larger than the 
sub-basal. Appendage of three nearly equal cells, the distal bearing terminally from one to 
three sterile, simple, tapering flexuous branches; the other two producing distally groups of 
autheridial branchlets arising from small cells cut off from their upper inner angles. Spores, 
45x3.7/i. Perithecia, 86x33/*. Primary appendage about GO fi, its longer branches 225- 
375 jx. Total length to tip of perithecium, average 200 /x.

Var. a, Plate IX, fig. 10-11. Larger than the type, the perithecia propoitionately narrower, 
becoming evenly suffused with amber yellow. Appendage often rclaf irely shorter with numer- 
ous sterile branches arising from all its cells, often crowded, and usually producing short 
antheridial branchlets. Perithecia, larger, 165x45/.. Spores, 44x4/.. Appendao^c, 37-

tips at maturity, the branches of the appendage fe^ in nun>l,er, with the antheridia borne in 
the typical fashion d.reetly from the main appendage ; in the variety very considerable differ- 
ences m s,ze and general habit are noticeable. While in the type two perithecia are unusual, in 
the var,ety there are sometimes five, uniformly tinged with amber yellow ; the appendage is apt 
to be much more eop.ously branched, and though this is not always the ease, it is often decidedly
