appendage serve to distinguish it. It is nearly allied also to the 

 smaller L. polyphaga. 



Laboulbenia eukop.ea, nov. sp. 



Amber-brown. Perithecium darker amber-colored, rather narrow, 

 its tip nearly straight, broad, black except the edges of the coarse lips, 

 which are turned slightly outwards, an olive shade extending below 

 the blackened portion. Outer appendage hyaline, suffused below with 

 olive-brown deeply colored externally near the base, simple or more 

 commonly consisting of a basal and a sub-basal cell which bears two 

 long slender tapering branches : more rarely the basal cell bears two 

 branches directly, the inner simple, the outer bearing two branches from 

 its basal cell. Inner appendage consisting of a basal cell which may 

 bear two branches directly, or more commonly is followed by a sub- 

 basal cell bearing a long simple sterile branch and a shorter fertile 

 branch producing several antheridia and one or two sterile divisions 

 which sometimes become elongate. Receptacle normal, a very slight 

 olive suffusion of the external surface of cell 4. Spores 55-59 X 

 4-4.5 fi. Perithecia 130-140 X 55 p.. Appendages (longest) 250 p.

Allied to L. Pterostichi, from which it is readily separated by its 

 amber color, its sparingly branched appendages, and by the shape of its 

 perithecium. 



Laboulbenia Quedii, nov. sp. 



Perithecium moderate, straight, slightly suffused with brownish, 

 darker externally just below the apex, the lips turned outwards, the 

 outer hyaline, the inner blackened. Outer appendage consisting of a 

 rather large basal cell bearing two branches, the outer strongly curved 

 outwards, usually bearing two secondary branches from its basal eel] 

 suffused with blackish ; the inner also similarly branched, the branches 

 long, tapering to a blunt point, often suffused with brown near the base. 

 The inner appendages commonly arise from two basal cells, the inmost 

 smaller and lower in position, each giving rise to a variable number of 

 appendages, usually not more than once branched, hyaline except tin: 

 outer one which is larger and usually suffused with brown near its 

 base. Receptacle elongate. Spores about 55 ^ long. Perithecium 

 185 X 50 fi. Longest appendages 370 p. Total length to tip oi 

 perithecium G30 n.
