X 55-60 [JL, but they were immature. Occasionally a peach pit is met 

 with, on which all the perithecia produce 8-spored asci, but in this case 

 the sporidia are smaller, 30-50 x 1 8-20 /j.. There are generally but 

 two of the larger sporidia in an ascus.

Spharia callicarpa, Curr. Linn. Trans. XXII, p. 321. tab. 58 fig. 62. 

 Caryospora callicarpa, Fckl. Symb. p. 163. 



Perithecia scattered, broadly adnate at base, |-1 mm. diam., car- 

 bonaceous, brittle, dull black, with a prominent, obtuse, tuberculiform- 

 conical ostiolum, which is finally deciduous, leaving the perithecium 

 broadly perforated above. Asci broad-clavate, paraphysate, about 

 200 X 50 /.< (210-260 x 60-70 pi, Winter). Sporidia subbiseriate, broad- 

 fusoid, with ends mostly curved in opposite directions, subhyaline, 75- 

 85 X 20-25 [1, 3-5-septate at first, finally broad-elliptical, with the ends 

 narrowly pointed, brown, nearly opake, 100-112 x 40-50 ft. 



On bark of decaying Platanus, Long Island, N. Y. (Zabriskie) 

 and on dead birch limbs, Hull, Canada (Macoun). 



The young sporidia are mostly distinctly constricted at the mid- 

 dle septum, but when mature, they are scarcely constricted, and the 

 color becomes so dark that the septa can hardly be seen. The asci in 

 the specc. examined did not seem well developed, and it is probable 

 that the measurements given by Dr. Winter are none too large. 



C. Langloisii, E. & E. Journ. Mycol. IV, p. 79. 



Perithecia gregarious, nearly superficial, their bases slightly sunk 

 in the matrix, depressed-conical, large (nearly 1 mm. across), dull black, 

 with a distinct papilliform ostiolum. Asci broad-oblong or narrow- 

 elliptical, subsessile, 120-140x40-45 /z, 8-spoi'ed, with abundant fili- 

 form paraphyses. Sporidia crowded in the asci, somewhat almond- 

 shaped or acutely elliptical, uniseptate and slightly constricted at the 

 septum, ends obtusely pointed, yellowish-hyaline at first, soon dark 

 brown, 35-45 x 16-20 fi and 3-septate. 



On old canes of Arundinaria, Louisiana (Langlois). 



The two additional septa (one near each end of the sporidium) 

 do not appear at first.

Perithecia adnate-superficial, carbonaceous, subglobose, papillate, 

 ostiolum soon perforated. . Often seated on a thin stroma or on the 

 blackened surface of the wood. Asci elongated, stipitate, 8-spored,
