Corethromyces bicolor nov. sp. 



Foot broader than the base of the long slender obconical receptacle; 

 which is opaque, the cell boundaries indistinguishable, except a small 

 translucent portion just above the foot, its distal end asymmetrically 

 furcate, owing to the presence of two blunt, hardly divergent lobes; 

 one larger and longer, lying at the left and overlapping a portion of the 

 venter; the other anterior, smaller and shorter, but otherwise similar. 

 The perithecium usually bent at a slight angle to the axis, slightly 

 inflated below, the region of the venter blackish olive, contrasting 

 rather abruptly with the perfectly hyaline distal half or more; which 

 tapers to the rather broad, slightly enlarged, somewhat rounded apex, 

 from the middle of which a short blunt projection extends upward; 

 the stalk-cell when partly visible, short, and hyaline. Appendage 

 more or less concealed by the longer lobe, hyaline; consisting of a short 

 axis with a few short hyaline branches on the inner side. Perithecium 

 50 X 16 fjL. -Receptacle to tip of longer lobe, including foot, 70-85 /x. 

 Total length 110-124 m, greatest width 20-24 m. 



On legs and inferior abdomen of a species of Cholcva. Aukland, 

 N. Z. No. 2143 (Messrs. Eames and Sinnott). 



This very striking species, which belongs to the group that includes 

 C. Qiicdiomichi, is at once distinguished by the coloration of its peri- 

 thecium, and by its elongate, opaque, bilobed receptacle. 



Corethromyces Valdivianus nov. sp. 



Basal cell of the receptacle much elongated, funnel shaped, opaque, 

 with a small translucent area above the foot; the blackening involving 

 the inner portion, or sometimes almost the whole, of the subbasal 

 cell as well as the outer half or more of the axis of the appendage; 

 the inner walls remaining hyaline, one or two of the terminal cells 

 usually not involved: subl)asal cell of the receptacle obliciuely placet!, 

 much flattened, its outer and sometimes its upper edge hyaline. Axis 

 of the appendage consisting of five or six cells, tapering somewhat 

 distally, and more or less distinctly curved toward the perithecium; 

 the branches short and scanty, pressed against the venter. Stalk- 

 cell of the perithecium hyaline or pale yellowish, oblique, somewhat 

 rounded, much broader than long, forming, with the subbasal cell and 

 the seconflary stalk-cell, a paunch-like protrusion of this region, which
