THAXTER. NEW LABOTJLBENIACEiE. 195 



On Catoscopus sp., Paris Museum, No. 119, New Guinea. On in- 

 ferior surface. 



Laboulbenia Polyhirmae nov. sp. 



Perithecium rather slender, almost wholly free, nearly hyaline or 

 faintly brownish yellow ; tapering slightly toward the moderately well 

 differentiated tip which is usually bent slightly outward, more or less 

 blackened on the inner side, sometimes wholly black, the inner lips often 

 prominently rounded and terminal. Receptacle concolorous with the 

 perithecium, marked by faint transverse striations, long and slender; 

 cell II usually greatly elongated; the distal portion small and normal. 

 Outer appendage consisting of a small basal cell more or less rounded 

 and producing distally from two to four branches, usually four ; an 

 outer and an inner, the two others placed between them one on either 

 side, the branches simple or usually not more than once branched above 

 the basal cell ; the branchlets slender, often flexed, rather closely septate, 

 hardly tapering: the inner appendage consisting of a smaller rounded ba- 

 sal cell which produces on either side a single branch, which may branch 

 several times and bears hyaline lateral or terminal antheridia singly 

 or in pairs; all the branches nearly hyaline. Perithecia 130-190 X 

 30-40 /x. Total length to tip of perithecium 400-700 /u, average 500 ft, 

 to insertion-cell 275-450^. Appendages, longest 350-400/*. Greatest 

 width 40-50,(1. 



On Polyhirma sp., Paris Museum, Nos. 5, 6, and 1G8, Tangar, Algeria.

Laboulbenia prominens nov. sp. 



Perithecium short and stout, less than half free from the receptacle, 

 nearly opaque blackish brown lighter distally, the short broad blunt 

 black tip rather abruptly distinguished on the inner side. Receptacle 

 rather stout, cells I and II dirty yellowish or subhvaline, the rest more 

 or less deeply suffused with blackish brown ; all the cells except cell I 

 marked by fine transverse striations more distinct on the suffused por- 

 tions ; cells III and IV large and prominent, the insertion-cell broad but 

 narrower than cells IV- V. Outer appendage consisting of a short 

 irregular cell abruptly narrowed distally and bearing two branches an- 

 tero-posteriorly, the outer externally deep blackish brown, once branched; 

 the outer branchlet also branched, the inner consisting of a short basal 

 cell which bears an inner and an outer branchlet, the branchlets pale
