Laboulbenia cauliculata nov. sp. 



Perithecium short and stout, straight or slightly curved, inflated more 

 prominently on its inner side ; dull olivaceous brown, translucent, or 

 becoming opaque ; the basal wall-cells forming a well-defiued pale 

 olivaceous or hyaline narrow stalk; the tip black, broad, not distin- 

 guished, except by its color ; the rather coarse, but not prominent, 

 lip-edges hyaline and outwardly oblique. Receptacle relatively short 

 ard small, the basal cell usually curved, narrow and subhyaline below, 

 becoming opaque and punctate distally ; the subbasal cell having only a 

 small portion of its posterior margin free, cell III being subtriangular 

 and overlapping it ; cell IV nearly as broad as, and somewhat larger 

 than cell III, separated from cell V, which may equal it in size, by a 

 vertical or but slightly oblique septum ; cells II- VI mostly translucent 

 yellowish brown, often becoming opaque. Insertion-cell rather broad : 

 basal cells of the appendages hardly distinguishable, the outer giving 

 rise abruptly to usually two erect, or slightly divergent, stiff, bristle- 

 like, curved branches, which are blackish brown, externally opaque, 

 producing short hyaline branchlets along their hyaline inner margins : the 

 basal cell of the inner appendage producing a branch on either side con- 

 sisting of from one to two cells from which arise several branchlets 

 similar to those of the outer appendages. Spores 58 X b ^. Peritiiecia 

 125-165 X 45-60 ju, including stalk (18-22 /i). Receptacle 90-100 X 

 35-40 ju. Appendages 125-185 /i. Total length to tip of perithecium 

 220-290 ^.

Var. prolixa nov. var. Perithecium straight or slightly curved, large 

 and greatly elongated, the body opaque ; the neck usually elongate, hya-

 and more slender, the two main branches of the inner often consisting of 

 from three to four cells. Sjjores 70 X 5 /<. Perithccia 365-540 X ob u,
