Basal and subbasal cells of the receptacle subcqual, the latter somewhat broader; tin lower mar- 
ginal cell relatively short and broad; the lower appendicular cell relatively taige; the up|M>r marginal 
cell bearing distally a long unicellular amber-brown outgrowth, about half the total length of the indi- 
vidual, projecting upward and outward at an angle of about 15°, with a slight terminal twist, and sub- 
tended by a prominent bulge of the cell which bears it: the distal appendicillate oeU relatively large and 
broad. Perithecium rather stout, the transverse limits of the Wall-0 Hfl indicated externally by more or 
less pronounced elevations, the blunt tip somewhat abruptly distinguished alum the nearly .straight 
inner margin. Total length to tip of perithecium, including foot, 130 ft, greatest width 33 n. Maiginal 
appendage 45-60 pi. Spores about 28 X 2.5 ft. Perithecium 75 X 20 ft.
