are nearly equal in size : the outer inflated and separated from the 

 cell above it by a blackened septum, this sub-basal cell roundish, 

 inflated, about as large as the basal cell and giving rise to two branches, 

 an outer and an inner ; the outer separated from it by a blackened 

 septum and consisting of a basal cell with three terminal brauchlets 

 the inner of which is deeply and broadly blackened at its base, while 

 the other two are wholly hyaline and fertile : the inner branch from 

 the sub-basal cell has no blackened basal septum and produces several 

 short branchlets bearing numerous antheridia. The inner appendage, 

 like the outer, consists of a roundish or squarish basal cell separated 

 from a sub-basal cell by a blackened sejDtum ; the sub-basal cell pro- 

 ducing a tuft of short branches bearing at their tips two to four 

 antheridia or becoming more elongate and sterile. Receptacle nor- 

 mal, the two basal cells rather slender, elongate, colorless ; the distal 

 cells suffused with blackish brown. Perithecia 110-120 X 40 /x. 

 Appendages (longest) 240 /x. Total length to tip of perithecium 

 333 /A, greatest width 63 /x. 



On Aspidoglossa suhangulata Chaud. Kansas (M. A. Barber). 



A species clearly marked by the peculiarities of its appendages, 

 which, unlike almost all other species of the genus, are fertile without 

 regard to their external or internal origin. 



Laboulbenia macrotheca, nov. sp. 



Amber-yellow. Perithecium large, evenly inflated, the curvature 

 from base to apex nearly symmetrical on either side, the apex rather 

 large, outwardly oblique, with a blackish basal shade ; the remainder 

 of the i^erithecium translucent, amber-colored, the walls thick, the 

 spore mass large. Appendages flexuous, thick, pale amber-colored 

 or tinged with purplish, arising from two cells, the inner small and 

 roundish, the outer much larger, two or three times as long, usu- 

 ally bearing a single cell with two terminal more commonly simple 

 branches; the inner producing two branches each several times 

 branched : the outer appendages especially more or less constricted 

 at the septa. Receptacle small, usually short and slender, the basal 

 cell long, narrowed towards its base, the sub-basal cell short, the 

 remaining cells relatively small. Perithecium 130-150 X 45-55 /x. 

 Spores GO x 5.5//, Appendages (longer) 185 /x. Receptacle 150- 

 165 X 35-40 /x. Total length to tip of perithecium 240 /x (longest 

 270 /x), greatest width 55-60 /x.
