H ad. On the dead stems and branches of the Common Raspberry (Rubus
Idceus) , frequent. Perennial.
Minute, gregarious, innate, bursting through the epidermis. Peritkecia
roundish, very black, slightly corneous, even, smooth, the margin indexed,
connivent, entire, thin, at length expanding, and leaving the rather
pale disk nearly plane. Asci forming a soft, nearly level stratum.
I have followed my learned friend IM. F r i e s in placing
this plant in his genus Excipula, but I fear it is rather too
nearly allied to Peziza. The genus itself is made up of species
formerly Pezizce, and unites those fungi with the Splice-
rice. With Pliacidium and Hysierium it has the nearest
aifinity, differing from the former in the perithecium remaining
entire, from the latter in its orbicular form, and from both
in the less corneous substance of the perithecium. The asci
are in the present species erect, and contain very minute oval
sporidia. On the application of moisture, the Excipttlce re-
