THAXTER. — NEW LABOULBENIACEAE. 315 



the rest broader than long, and separated by somewhat oblique septa ; 

 the hyaline appendiculate cells relatively large, and not concealed by 

 the appendages, which are rich black brown, the lower ones, when un- 

 broken, extending upward far beyond the tip of the perithecium and curved 

 toward it : those arising about its base, and even below it from the inner 

 cells of the appendiculate series, unlike the rest, erect, straight, consisting 

 of a paler basal part, five to six septate, with constrictions at the septa, 

 and a distal unicellular more or less elongate portion. Perithecium (not 

 fully matured) about 85 x '25 fx. Receptacle 75-1 Co x 15-18 /x. The 

 longest appendages about 300-350 /x.

Laboulbenia bilabiata nov. sp. 



Form stout, the basal cell of the receptacle nearly hyaline, the sub- 

 basal becoming amber-yellow, the parts above it clear amber-brown. 

 Perithecium stout, nearly symmetrical, tapering to the broad tip, the an- 

 terior lip-cells modified subterminally to form a closely approximated pair 

 of broadly rounded projections, which are subtended on the inner side by 

 the slightly prominent rounded apex, which is in turn subtended by a 

 blackish suffusion of no great size. Receptacle normal, rather short and 

 stout, the basal and subbasal cells slightly prominent anteriorly, of nearly 

 equal length, the walls very thick and striate. Appendages normal, the 

 outer consisting of a black-brown basal cell, twice as long as broad, bear- 

 ing distally the two divergent branches, which are mostly once branched 

 (antero-posteriorly), all the lower cells suffused with brown, becoming 

 hyaline toward the tips : the inner appendage consisting of a basal cell, 

 slightly shorter than that of the outer, paler brown, bearing the normal 

 branch on either side ; the branchlets more or less elongate, or bearing 

 loose tufts of antheridia. Perithecium 240 X 75 t*, including the terminal 

 projections, which measure 25x22^.. Receptacle 225-250 /x. Total 

 length 450 X 1 15 p. Appendage 200-300 u.

Laboulbenia olivacea nov. sp. 



Perithecium nearly free, broader distally. olivaceous brown, paler and 

 subhyaline distally on the inner side ; the inner margin bulging character- 

 istically above and curved abruptly outward to the tip, which forms a flat
