black and rough, amphigenous (chiefly hypophyllous, but a single 

 stroma sometimes erumpent on both surfaces of the leaf), not 

 observed to be caulicolous or fructicolous, bearing 7-100 or more 

 perithecia; perithecia large, reaching 1.5 mm. in length, approxi- 

 mately 0.5 mm. in lateral diameter, in some cases much crowded 

 and covering the whole surface of the stroma, in others scattered 

 or developed only at the margin; young perithecium conical to 

 short cylindrical, the apex smooth, rounded, and undifferentiated, 

 the ascus-bearing cavity partially buried in the stroma, pure white 

 within and the surface roughened with minute markings ; mature 

 perithecium very characteristic, the lower half globose to sub- 

 cylindrical and roughened like the stroma, the upper half trisul- 

 cate and trilobed giving a triangular appearance in transverse 

 section, smooth to shiny, the apex subtruncate and trilobed-um- 

 bilicate, the apical furrows running half way down the sides of 

 the perithecium ; dehiscence taking place along these furrows, 

 the upper half of the perithecium becoming deeply tri-cleft, the 

 three lobes pulling apart and turning back, exposing the lighter 

 colored inner surface of the perkhecial wall and giving a 3- 

 pronged apex ; in rare cases one or more perithecia on a stroma 

 showing only a bilobed apex and resembling closely the typical 

 perithecium of C. portoricensis; in other cases, an occasional peri- 

 thecium quadrilobed, a condition also met with in C. jamaicensis; 

 asci ellipsoidal to ovate, 22-30 X 34-42 /x. (p. sp.), typically 8- 

 spored, asci containing a fewer number of spores uncommon ; 

 spores 10-13. 5 fi (mostly 12-13.5 fO in diameter. 



Parasitic on Podocarpus angustifolia, P. Sellowii, P. chilina, 

 and P. macrostachys. Probably occurs also on other species of 

 this genus. The type material collected on P. angustifolia. 



Corynelia oreophila, C. portoricensis, C. jamaicensis, and C. 

 brasiliensis are very closely related species. Of these C. bra- 

 siliensis is easily separated from the others by the wedge-shaped 

 apex of its perithecium. Corynelia oreophila may be distin- 

 guished from the remaining two by its typically 8-spored ascus. 

 In the material of this species studied less than 5 per cent, of the 

 asci contain fewer than eight spores. A few 6-spored asci, fewer 

 5-spored asci, and one 2-spored ascus have been observed. This 

 variation is not correlated with the variation in the number of 

 lobes at the apex of the perithecium. Slides made from bilobed 

 and quadrilobed individuals show typically 8-spored asci. In 

 Corynelia portoricensis and C. jamaicensis approximately 80 per
