Stroma elViisod, thin, a])]»lanatc, black, variable in fbriii and size, 

 (iltcn in nanow, olon,<j;atod strii)s 2-3 mm. wide and 3-6 cm. lonu', but

 J,-l cm. wide. Perithccia subi>'loI)(>se, crowded, rather large, i-ounded 

 and ])romiuent above or rarely slightly depressed around the central 

 papilla, then only slightly prominent, and the surface of the sti-omn 

 not so distinctly roughened. Conidial layer pulverulent, cinereous.

 septate sterigmata. Asci cylindrical, long-pedicellate, 75-100 // long

 uniseriate, sulicylindrical, rounded at the ends, olilong-cylindrical, sub- 

 inoipiilateral or almost curved, seldom sti-aight, becoming dark. 12-

On decaying wood (seldom on the bark) of various deciduous 

 trees. 



This is called a connnon and widely diffused species, l)ut as we 

 have some doubt as to wh(>tiier we properly understand it, we have 

 taken the above descri]»tion from Xitschke's Pyr. Germ. The speci- 

 mens distril)ntcd in N. A. F. under this name are certainly not the 

 typical form, for the i)ei'ithecia are small, mostly |- mm. or less, and 

 oidy sliu'htly jirominent, and the sporidia are mostly only S-10.\3-4 m. 

 'J'iie N. A. F. specimens appear to Ite the same as the //. coUiculoimnt.
