Rhachomyces Dolicaontis nov. sp. 



Form elongate. Cells of the main axis of the receptacle twenty to 

 thirty-five, more or less dirty brownish, banded with dark blackish brown 

 below, while the more slender proximal cells are usually opaque ; the axis 

 of nearly equal diameter throughout and nearly straight above about the 

 eighth cell ; each cell containing distally one, the axis cells two, roundish 

 or oblong brown bodies (possibly thickenings of the walls) which suggest 

 the stigmata of an insect larva. The appendages somewhat divergent, 

 opaque, except a narrow upper hyaline margin, short, stiff" and numerous ; 

 those external more slender, slightly curved and sharply pointed ; those 

 between somewhat stouter and longer, with slightly recurved tips ; those 

 about the base of the perithecium, which they do not conceal, but slightly 

 longer and few in number. Perithecium short-stalked, slightly more 

 or less symmetrically inflated, dull brown, minutely punctate or granular, 

 not uniformly suffused ; the tip with darker shades, the blunt apex 

 hyaline. Spores 66 X 5 ^w. Perithecia 150-200 X 42-60 /x, including 

 the basal and stalk-cells. Larger appendages 90-110 /x, smaller about 

 75 /A. Total length 600-1100^, the average diameter about 30-35 /x.
