Laboulbenia incerta nov. sp. 



Perithecium erect or slightly divergent, rather pale or rarely darker 

 translucent dirty brown, considerably, almost symmetrically, inflated, 

 slightly broader below ; the basal wall-cells forming a very short, often 

 almost obsolete, hyaline stalk ; the tip rather abruptly distinguished, 

 usually bent slightly outward, short, stout, wholly suffused, darker 

 below ; the apex evenly rounded as a rule ; the outer lip-cells curved 

 outward to the external pore. Receptacle normal, hyaline, or faintly 

 yellowish ; the distal portion short and broad ; the basal cell relatively 

 short; cells III and IV subequal. The insertion-cell slightly oblique, 

 black, contrasting, the opacity usually involving a part or the whole of 

 the basal cells of the outer and inner appendages. Appendages similar 

 to those of L. perplexa, more compact, with shorter branches ; outer 

 appendage consisting of about six to eight obliquely superposed cells, 

 the branches divergent, curved upward ; the two cells of the basal part 

 stout, clear brown, constricted at the dark septa, roundish to long-oblong ; 

 the distal part rather stout, unicellular, tapering to a blunt apex and 

 seldom reaching beyond the tip of the perithecium ; the two branches of 

 the inner appendage similar to the outer, except that the two lowest 

 branches consist of a single cell, its basal septum alone dark and con- 

 stricted, bearing distally a single brown antheridium. Spores 95-100 X 

 8 f,. Perithecia 185-250 X 60 fi. Receptacle 185-290 X 70-80 ,x. Ap- 

 pendage 200-250 fx. Total length to tip of perithecium 360-500 /x.

Laboulbenia insignis nov. sp. 



Perithecium free except the base, straight, nearly symmetrical, brown, 

 translucent or transparent, paler below; the wall-cells spiral, describing 

 about half a turn from the base to the tip ; which is abruptly distin- 

 guished, nearly symmetrical, abruptly opaque below the broadly subhya- 

 line, faintly brownish lips, which are not prominent and form a somewhat
