THAXTER. — NEW LABOULBENIACEAE. 33 



narrow, but rather abruptly distinguished, especially cells III and IV, 

 more or less deeply suffused, becoming concolorous with the perithelium. 

 Outer appendage long, slender, simple, or rarely distally furcate, curved 

 outward; the basal cell of the inner appendage relatively very small, 

 bearing a single, erect, short, one-celled branch; which, after bearing 

 several antheridia distally, soon disappears. Spores 75 X 5 /a. Peri- 

 thecia 180-210 X 48^. Receptacle 150-325 ,u. Appendages longer, 

 300-375 fi. Total length to tip of perithecium 280-500 /x.

Laboulbenia curvata nov. sp. 



Perithecium large and long, strongly curved inward throughout, rich 

 deep red-brown, the inner half usually opaque, the outer more or less 

 translucent or becoming opaque ; the basal wall-cell forming a well- 

 defined, short, hyaline stalk; the tip short and broad, suffused about 

 the terminal nearly median pore. Receptacle short and stout, trans- 

 lucent, more or less deeply and unevenly suffused with dirty brown; 

 the basal cell paler, or nearly hyaline below, often as long as the rest 

 of the receptacle above it, obscurely punctate ; the subbasal cell short, 

 a very small part only of its anterior margin free; cells III and IV 

 subequal, or cell IV larger, separated by a very oblique septum, a small 

 portion only of the outer margin of cell IV free. Insertion-cell slightly 

 oblique, brown or black, the suffusion involving the basal and even the 

 subbasal cells of the appendages. Appendages similar to those of 

 L. perplexa, consisting of from six to eight obliquely superposed cells, 

 the branchlets usually much shorter than the perithecium, the two 

 lowest cells of the branches of the inner appendage bearing distally a 

 pair of deep brown divergent antheridia, the long slender necks curved 

 rather abruptly distally. Spores 70-75 X 4|U. Perithecia 325-400 X 

 50-70 ju, including the stalk (40-55 ,u). Receptacle 185-220 X 75-90 /*. 

 Total length to tip of perithecium 500-600 ,u.
