THAXTER. — NEW LABOULBENIACE.E. 169 



brown suffusions about the distal region of cell I and the basal region of 

 cell II ; the basal cells of the perithecium opaque and cell IV and V 

 more deeply suffused ; a series of prominent blackish brown tuberculate 

 rido^es extend more than half way across the receptacle from the anterior 

 margin, beginning below the insertion cell and present as far as the base 

 of cell II; cell IV bulging distally outside the insertion-cell. Outer 

 appendage simple, erect, tapering, yellowish, perhaps once branched above 

 the basal cell ; inner appendage consisting of a smaller basal cell with a 

 similar and shorter branch on either side. Perithecia 120 X 37-40 /x. 

 Total length to tip of perithecium 340 [x ; to insertion-cell 200 fx. ; greatest 

 width 60 /x. Appendages \85 fx.

Laboulbenia Cubensis nov. sp. 



Perithecium short and stout, free except ^at the base, slightly curved 

 toward the appendages, blackish olive, the lip-cells prominent but flat- 

 tened backward and outward. Receptacle elongate, cells I and II dirty 

 olive, cell III hyaline, long, contrasting with cells IV and V, which, 

 together with the basal cells of the perithecium, are deeply suffused with 

 blackish olive ; cell VI as long as cell III and lying beside it, becoming 

 tinged with dirty olive ; basal cells of appendages dark olive, indistin- 

 guishable, producing concolorous prominences which give rise to a 

 number of hyaline branches, the basal cells of which are large, swollen 

 distally, and bear numerous terminal and subterminal branchlets exter- 

 nally ; the branchlets once or twice branched, the septa olive. Perithe- 

 cia 155-190 X 75-85 /x. Total length to tip of perithecium 480-800 [x. 

 Appendages, longest 140 /x.

Laboulbenia dactylophora nov. sp. 



Perithecium relatively small, its upper third only free from the recep- 

 tacle, translucent smoky brown, the tip prominent, not abruptly differen- 

 tiated, its upper half hyaline, black-tipped, symmetrical or irregularly 

 sulcate, the lower half blackened. Receptacle very elongate, concolorous 

 with the perithecium or paler, finely punctate, tapering below, its curved 

 base hyaline, the basal cell expanding distally to the very broad upper 

 septum, which forms the middle of a somewhat one-sided enlargement 

 involving the adjacent extremities of cells I and II, cell II more dis-
