Amphigenous, scattered, l)lack. Perithecia subglobose, super-

 rounded at the ends, scarcely constricted, uniseptate, yellowisli, 12-15

Spots reddish-brown or brownish, sometimes with a grayish cen- 

 ter. Perithecia amphigenous, minute (70-80 /i), black, with a few 

 short, straight, diverging, black bristles 30-40 p long around the 

 apex. Asci oblong, gradually and slightly narrowed above, 40-45 x 

 8-10 . Sporidia biseriate, oblong, quadrinucleate, 12x5 //. 



On living leaves of Cassandra calyculata, Caroga, N. Y., and on 

 leaves of Andromeda poUfolia, London, Canada (Dearness). 



The perithecia are found mostly on the lower side of the leaf. 

 Thev are so small as to be scarcely visible to the naked eye. Some-

times they emerge from beneath the scales of the leaf, so as to appear 

 erumpent, but they are really superficial. 



In the Canada specimens the asei are 40-45 x 15-20 //. Sporidia 

 ovate-oblong, 12-18x4-5 //, which are about the same as our meas- 

 urements of the asci and Sporidia in a specimen from Peck.

Perithecia scattered or subgregarious, hypophyllous, globose, 

 80-115 IJL diam., thickly clothed with dark, bristle-like, spreading 

 hairs 60-100 x 5 (j.. Texture of the perithecia (which finally collapse), 

 very thin and pale. Asci oblong-cylindrical, sessile, 30-35 x 7-8 JJL. 

 with paraphyses. Sporidia biseriate, subcylindrical, hyaline, (8-10 x 

 2 fj., Sacc.) 



On fallen leaves of Andromeda racemosa, Newfield, N. J 

 The bristles are abundant, and those arising from the lower part 

 of the perithecia are slightly curved inwards. The specc. examined 

 were immature and the Sporidia continuous.
