 turned slightly outward. Receptacle amber-colored, deeper anteriorly,

 perithecium comes opposite cell III. Insertion-cell and the inner margin 

 of cell V usually free from the perithecium. The outer append 

 -implc divergent, tlie basal cell very targe; the basal cell of the inner 

 appendage much Bmaller, bearing one to two Bhort branchlets. Spores

Laboulbenia Oopteri nov. bo. 



Perithecium three fourths or more free, translucent blackish brown, 

 the inner margin evenly curved outward, the outer margin with slight 

 elevation- at the septa ami curved abruptly inward to form the well 

 differentiated tip which is pale brownish, with dark inferior Buffusions. 

 Receptacle concolorous with perithecium, except that cells I and II are 

 usually hyaline, the suffused portion- Bparsely and rather coarselj and 

 distinctly punctate. Iusertiou-cell broad and black. Basal cell of the 

 outer appendage for the most part very long, bearing distally an outer 

 and an inner branch, the former with blackened basal septum, Bimple, 

 or once branched in which case the basal septum of the outer branchlet 

 is also blackened. Inner appendage consisting of a very small basal cell 

 hearing a short branch on either side. Perithecia 95-110 • 30-35 ,,. 

 Total length to tip of perithecium 17o 275 n ; to insertion-cell 85-160 ft. 

 Appendage broken. 200 ft, probably much longer.

Laboulbenia Ophoni nov. sp. 



Perithecium free except at the base, short and stout, pale straw-colored 

 or nearly hyaline, somewhat inflated ; the inner margin more convex, the 

 black tip abruptly differentiated on its inner side. Mack, contrasting, the 

 lip-edges hyaline turned slightly outward. Receptacle Bhort, -tout, nor- 

 mal, concolorous with the perithecium. Insertion-cell black, contrasting. 

 The outer appendage divergent, simple or once to three times branched, 

 the ultimate branchlets distally attenuated ; the inner appendage consist- 

 ing of a basal cell half as large as that of th iter, bearing a short branch 



on either side which may he several times branched, the antheridia borne 

 i;i small groups. Spores 28x3^. Perithecia 70x30-3-1./. Total
