THAXTER. — NEW LABOULBENIACEAE. 307 



Chitonomyces Javanicus nov. sp. 



Foot relatively small. Basal cell of the receptacle small and narrow, 

 its basal half or more suffused with dirty blackish-brown, above hyaline ; 

 subbasal cell longer than the basal, and of nearly the same diameter 

 throughout ; the three cells above it subtriangular, about equal in size, 

 darker straw-colored, or pale amber-brown : the lower marginal cell of 

 the distal portion of the receptacle narrow, clean cut, darker amber- 

 colored ; the lower appendiculate cell above it hyaline, small ; the two 

 remaining cells above and external to it, forming an opaque appendage 

 shaped like a knife-blade, its tip rounded outward from the inner side to 

 an external blunt apiculus. Perithecium suffused below with pale amber- 

 brown, long and slender, narrower opposite the insertion of the lower 

 appendage, expanding slightly above it, the small hyaline apex curved 

 inward and subtended externally by an erect, clear, dark amber-brown 

 projection, hardly or not at all exceeding it; and on the inner side by a 

 larger, broader, less deeply colored, spreading cell, which is curved 

 toward the receptacle, the blackened portion of which projects about half 

 its length above it. Total length to tip of perithecium 165-185 u, to the 

 tip of the black prolongation of the receptacle 180-200^, greatest width 

 22-25 (i. Perithecium 90-110 X 16 u. Basal portion of the receptacle 

 75 u, including the slender foot. 



On the margin of the left elytron of Laccophilus sp., Java. 



Chitonomyces spinosus nov. sp. 



Basal and subbasal cells of the receptacle subequal, the latter some- 

 what broader; the lower marginal cell relatively short and broad: the 

 lower appendiculate cell relatively large ; the upper marginal cell bearing 

 distally a long unicellular amber-brown outgrowth, about half the total 

 length of the individual, projecting upward and outward at an angle of 

 about 45°, with a slight terminal twist, and subtended by a prominent 

 bulge of the cell which bears it : the distal appendiculate cell relatively 

 large and broad. Perithecium rather stout, the transverse limits of the 

 wall-cells indicated externally by more or less pronounced elevations, the 

 blunt tip somewhat abruptly distinguished above the nearly straight inner 

 margin. Total length to tip of perithecium, including foot, 130 /a, greatest 

 width 33 m. Marginal appendage 45-60 ^. Spores about 28 X 2.5 p, 

 Perithecium 75x20 «. 



On the left posterior leg of Laccophilus sp., Java.
