sporidia. The habit is almost the same as that of Cal. pnnceps. The 

 decumbent ostiola are often 1 mm. or more long, and perforate the 

 epidermis with a circular opening.

Perithecia circinating or scattered, about J mm. diam., gloliose 

 and tuberculose-roughened, lying on the surface of the inner bark or 

 slightly bedded in it, their long (sometimes as much as 1 mm), slender, 

 cylindrical, decumbent necks converging and piercing the epidermis 

 in a small, compact fascicle, but not united in a disk and only slightly 

 projecting. In the scattered forms often densely gregarious, with the 

 ostiola erect and separate, and the perithecia more or less sunk in the 

 bark. Asci p. sp. 32-40x4 //, clavate or olavate-cylindrical. Sporidia 

 biseriate, cylindrical, nearly straigh«t, 5-6' x lJ-2 /z. 



On decaying white oak limbs lying on the ground, and on cast oif 

 maple bark. New field, N. J. 



The ostiola are slightly swollen above and, except the bare, black 

 tips, covered with an olive-brown pubescence.

Perithecia circinate in orbicular or oblong groups, globose, gla- 

 brous, black, nearly \ mm. diam., 12-20 together, necks decumbent, 

 of variable length, converging to the center with their obtyse, swollen 

 tips barely erumpent through short, transverse cracks in the thick epi- 

 dermis. Asci 25-30 X 4 ;i (p. sp.), with long, stout, lanceolate paraph- 

 yses. Sporidia subbiseriate, oblong-fusoid, scarcely curved, hyaline,

On dead birch limbs, Bethlehem, Pa. (Schw.), Maine (Harvey),

When the epidermis is peeled off, the perithecia come with it. 

 The ostiola are said to be sometimes 1 mm. long. In the specc. we 

 have seen they are short.

 trating the substance of the bark, elegantly circinate, suberect joined
