THAXTER — NEW LABOULBENIACE^. 157 



Laboulbenia angularis no v. sp. 



Perithecium wholly free, symmetrically inflated, straight, evenly suf- 

 fused with smoky brown except the very short narrow hyaline neck-like 

 base ; the tip well differentiated, black, distally hyaline, the whole peri- 

 thecium inserted nearly at right angles to the axis of the receptacle. 

 Receptacle amber-yellow or amber-brown, the basal cell tinged with 

 smoky brown, cell II abruptly broader and long, all the cells except cell 

 I more or less conspicuously marked by short transverse striae, cell V 

 bulging on the inner side and carrying the black insertion-cell out free 

 from the neck of the perithecium. Outer appendage consisting of an erect 

 series of about six obliquely superposed cells, the lower becoming nearly 

 opaque, the basal one larger and darker, opaque externally and below; 

 each cell bearing externally a single simple branch, the branches consist- 

 ing of a basal portion of three short cells prominently constricted at the 

 blackish septa, and a terminal portion (broken in the types) : the inner 

 appendage consisting of a basal cell which gives rise to a series of super- 

 posed cells on either side, like that of the outer appendage and similarly 

 branched, one of the series in the types much shorter than the other (two 

 and four celled), the branches all erect, closely apposed, more or less suf- 

 fused with brownish. Perithecia 280 X 45-55 /x. Total length to tip 

 of perithecium 680 /x ; to insertion-cell 420 /x ; greatest width 75 fi. Ap- 

 pendages (broken) 55 fx. 



On Galerita unicolor Dej., Brit. Mus. No. 516, Amazon River. In- 

 ferior surface of prothorax. 



Laboulbenia anomala nov. sp. 



Perithecia nearly symmetrical, free except at the base, tapering dis- 

 tally, the tip somewhat lighter, subtruncate with one (or more ?) of the 

 lip-edges modified to form a prominent large somewhat irregular blackish 

 brown median projection which causes the tip to appear notched on the 

 inner side. Receptacle dirty olive-brown, finely punctuate, the whole 

 curved almost to a horseshoe form : cells I and II about equal in length 

 and diameter, the base of the perithecium opposite cell III, insertion-cell 

 unmodified external subtriangular, cell V similar to it, about twice as large 

 and occupying a corresponding position on the inner side ; the two to- 

 gether with the terminal portion of cell IV, on either side of which they 

 lie, form the free broadly clavate terminal portion of the receptacle above 

 the narrower and also wholly free basal half or more of cell IV. Basal 

 cells of appendages not distinguishable, giving rise to a number of promi- 

 nences (about twelve) each forming the base of a branch, the branches
