On the lower surface of leaves of Quercus, more rarely Castanet/. 

 Fagus, ^E*<'nhis, Carya, Cornus and some others, common. 

 The pynnnyniv is from Winter's Pilze.

Perithecia hypophyllous, thickly gregarious, forming small, black, 

 angular spots J-l mm. across, and limited by the nerves of the leaf, 

 innate-prominent, punctiform, globose, 70-80 tj. broad, black and luster- 

 less, pierced above. Asci clavate-cylindrical, sessile, 50-60 x 7-8 //.. 

 Sporidia biseriate, obovate-oblong, uniseptate, more or less constricted 

 at the septum, hyaline, 9-14 x 3-4 p. (or sometimes only 2 p. wide). 



On leaves of Quercus, Castanea, Fraxinus, ^Escuhis and other 

 deciduous trees, common. 



Winter (in Die Pilze, p. 383) remarks that this species is usually 

 gathered in the autumn, while the perithecia are still immature, so 

 that the specimens in the various Exsiccati are, for the most part, un- 

 reliable.
