H ab. On the dead branches of various trees, b u t generally on those of the
Beech (Fagus syhatica) ; at all seasons, extremely common.
Gregarious, bursting through the bark, circular, about two lines in breadth,
depressed, hrownish-hlack, whitish within, glabrous, even, dotted with
the orifices of the immersed perithecia. Perithecia mostly ovate, terminating
in a narrow neck, and not at all exserted. Asci elongated, attenuated
at each extremity. Sporidia yellow, oval and simple, as far as I
could perceive in my specimens, b u t bi-septate, according to the figure
published by Professor N e e s v o n E s e n b e c k .
One of the most common Sphcerice in existence, at least in
Europe and North America, where S c h w e i n i t z finds it “ copia
incredibili.”
