which IS bent abruptly inward almost at right angles. Receptacle yellow- 

 ish brown, deeper in the region of cell III, the basal cell slightly curved, 

 its upper half rather abruptly expanded ; a more or less distinct bulge 

 below the perithecium. Outer appendage usually simple, stout, the basal 

 cell of the inner usually much smaller bearing a branch on either side 

 usually once branched above the basal cell ; all the branches stout and 

 constricted at the lower septa. Spores 60 X 4: jn. Perithecium 100-125 X 

 37 jM. Total length to tip of perithecium 200-270 /<; to insertion-cell 

 135-1 GO ,(/. Greatest width 55 ^.

 Vale de Chiriqui, Panama. On margin of elytron. 



Laboulbenia Clivinalis nov. sp. 



Usually rather slender. Perithecium three fourths or more free, more 

 or less deeply tinged with blackish olive-brown, distally curved slightly 

 outward, the tip black with hyaline lip-edges. Receptacle wholly hya- 

 line, or cells III and IV becoming more or less suffused with blackish 

 brown, the suffused areas punctate : bulging distally below the perithe- 

 cium. Insertiou-cell well differentiated, black. Appendages consisting 

 of an inner and an outer basal cell, which may remain simple or become 

 longitudinally divided, sometimes also transversely or even obliquely : 

 the outer basal cell hyaline, often several times as long as broad, its dis- 

 tal septum blackened ; when simple, bearing a single branch, if divided, 

 several ; the basal cell of the outer branch usually rather short and some- 

 what suffused, commonly bearing two branchlets. The basal cell of the 

 inner appendage usually smaller than that of the outer, sometimes equal, 

 and like it simple or divided ; when simple, bearing a branch on either 

 side, or more if it is divided. All the branches of both appendages hya- 

 line or nearly so, mostly once branched above their basal cells. Spores 

 about 55 X 4.5 /i. Perithecia 120-150 X 35-50 jM. Total length to tip 

 of perithecium 275-400^; to insertion-cell 200-340^. Appendages, 

 longest 300-400^.
