(Figures 13-18) 



Stromata scattered, infrequently confluent, more or less defi- 

 nitely circular, 1-3 mm. in diameter, chiefly hypophyllous, but 

 often amphigenous, caulicolous, and fructicolous, not usually 

 erumpent before the delimitation of the perithecia, in section 

 homogeneous and black or dark-brown, externally dull black and 

 minutely roughened, bearing finally a crowded cluster of 20-50 

 or more perithecia ; perithecia first making their appearance 

 through the ruptured epidermis as hemispherical protuberances 

 on the stroma, the ascigerous cavity being partially buried and 

 pure white within ; the young perithecium cartilaginous, soon at- 

 taining a characteristically conical form, the apex smooth and 

 shining, the base rough and dull, later protruding farther and 

 developing a cylindrical neck which becomes clavate by the pro- 

 nounced enlargement of the tip ; perithecium at maturity ap- 

 proximately 1 mm. in length, brittle, somewhat dumb-bell shaped, 

 usually bent in the narrow, middle portion and appearing conse- 

 quently inequilateral, this being especially pronounced in those 

 individuals borne at the margin of the stroma ;' the swollen apex 

 of the perithecium at maturity flattened and deeply cleft by one 

 to several transversely running furrows, the resulting ridges 

 usually breaking up into scales, giving the apex of the perithecium 

 a pronouncedly shaggy appearance, finally dehiscent along the 

 line of the middle furrow by a wide and deep split, the two lips 

 pulling apart and usually recurving thus exposing the ashy to 

 brown inner wall; asci 20-26X34-44/^ (p. sp.), 8-spored ; 

 spores 9-14 (mostly 12 in diam. ; pycnidia sometimes de- 

 veloped on the stroma ; pycnospores elongated, 5-7 X 2 ju. 



Parasitic on Podocarpus elongata, P. latifolia, P. Nagem, P.
