Perithecia gregarious, on bleached areas of the limbs, punctiform, 

 minute, 100—120/* in diameter, covered by the epidermis, through 

 which they are visible as minute black specks, giving the part of 

 the limb occupied a smoky appearance : sporules ovate-elliptical, 

 4-5.5 x 2-2.5 /i. 



Differs from P. negundinicola Thum. var. ramicola E. & E. in 

 its much smaller perithecia and sporules. Var. infuscans is found 

 with the normal form and differs only in being accompanied with 

 a subepidermal Macrosporium and toruloid mycelium which black- 

 ens the surface of the limb when the bleached epidermis falls off.
