Laboulbenia Misceii nov. sp. 



Peritbeciura free, long aud slender, translucent, pale brownish olive, 

 narrowed at the base to form a short paler stalk which lies opposite the 

 insertion-cell; the tip long, not very abruptly distinguished, paler below, 

 straight or turned slightly outward, distally blackened on the inner side ; 

 the lips variable, rather prominent. Receptacle rather short and stout, 

 darker olive-brown ; the basal cell pale yellowish. Insertion-cell nearly 

 as broad as cells IV-V. Basal cell of outer appendage blackish brown 

 externally, bearing a single terminal branch of less diameter externally 

 suffused with blackish brown, slightly curved outward and bearing two 

 or three branchlets from the inner side which are hyaline, the basal cells 

 somewhat suffused with brown ; the basal cell of the inner appendage 

 smaller than that of the outer, nearly hyaline and bearing a branch on 

 either side similar to the outer appendage. Perithecia including base 

 145-180 jx. Total length to tip of perithecium 210-300 ft ; to insertion-

Laboulbenia obtusa nov. sp. 



Perithecium about three fourths free, becoming opaque, black-brown, 

 very stout, the outer margin slightly and more or less symmetrically 

 convex, the inner bulging prominently distally aud curved abruptly to 

 the brown blunt rounded hardly differentiated apex, the pore external. 

 Receptacle short, cell VI together with the basal cells of the perithecium 

 concolorous with the latter, becoming indistinguishable; cell VI ex- 

 tending to or towards the base of cell II, which is mostly suffused above, 

 hyaline and contrasting below as is cell I ; cells III and IV with 

 median brown shades. Insertion-cell black-brown. Appendages hyaline 

 becoming tinged with brown, the outer basal cell twice as long as the 

 inner, each bearing one to two branches which form a compact group 

 curved toward and against the perithecium. Perithecium 120 X 65 /i. 

 Total length to tip of perithecium, average 260 /x ; to insertion-cell 

 175 /x. Appendages, broken, 35 a/.
