NEW INDO-MALAYAN LABOULBENIALES. 9 



much narrower, lateral in relation to the base of the antheridiuni. 

 Basal cell of the appendage hyaline, separated from the rest of the 

 appendage by a thin dark septum, the rest of the appendage about the 

 same diameter throughout, two to three celled, the basal cells shorter, 

 the tip bluntly rounded. Antheridium solitary, arising from the 

 subbasal cell of the receptacle, its base resting almost wholly on the 

 basal cell; its stalk-cell short and broad, distally slightly pointed; 

 the antheridial cells four with clearly distinguished basal cells; the 

 venter short and rather stout; the neck stout, purplish, not abruptly 

 distinguished, relatively long and stout, curved and slightly tapering 

 throughout. Receptacle, exclusive of foot, 10 X 9 m- Antheridium 

 18X6)U. Appendage 20-24 m- Total length to tip of appendage 

 about 30 jj.. 



Female individual. Receptacle prostrate, its three successively 

 larger cells flattened, somewhat obliciuely superposed, not distin- 

 guished from the basal cell of the appendage; the whole, including the 

 foot, subtriangular; the lower (outer) margin straight, the upper 

 divergent from the foot to the upper angle of the basal cells from 

 which it conAerges to the thin dark terminal septum which separates 

 the basal cell from the rest of the primary appendage; which is two 

 to three celled, rather stout, the lower cells short, the tip bluntly 

 rounded. Secondary appendage solitary, arising from the subbasal 

 cell of the receptacle; when growing on the abdomen bent abruptly 

 upward at right angles to its axis, erect, its long basal cell sometimes 

 rather deeply suffused, and followed by two nearly equal thin-walled 

 purplish cells, slightly longer than broad; the rest of the appendage 

 mostly hyaline, one to two-celled; when growing on the foi'ceps 

 smaller, shorter, and lying nearly parallel to the axis of the receptacle. 

 Perithecia solitary, arising from the thirtl cell of the receptacle, curved 

 abruptly upward at its abruptly broadened base, erect; the stalk 

 elongate, broader below, distally merging gradually with the faintly 

 purplish body of the perithecium ; which is hardly distinguished from 

 it, slightly asymmetrical, its inner margin nearly straight, the outer 

 convex; the tip not distinguished, except near the apex which is 

 subtended externally by a more or less well defined hump or promi- 

 nence; the lip-cells Aariably somewhat asymmetrically prominent, 

 slightly oblique inward, that is away from the secondary appendage. 

 Body of perithecium 45 X 12^ (ascigerous portion), the stalk 70- 

 80 X 10 M, at base. Spores about 28 X 2. .5 m- Receptacle, including 

 basal cell of appendage and foot, 20 X 10 m- Primary appendage, 

 exclusive of basal cell, 12-16 X 5 yu. Secondary appendage 35-45 X 

 5.5 iJL.
