H ab. On the dead leaves of the Holly (Ilex aqufolium), frequent at all
seasons.
Perithecia scattered or gregarious, nearly a line in breadth, adnate with
the epidermis, very black, shining, plane or slightly convex, so completely
innate as to occupy both surfaces of the leaf, dark brown within
; the centre of the perithecium at length opens by 3-5 acute, somewhat
regular, short segments, which become almost erect. Within the
cellular perithecium are 3-5 ovate, blackish masses or nuclei, composed
entirely o f sporidia, and which, under favourable circumstances,
dissolve, and discharge the sporidia by the opening of the perithecium.
The sporidia are whitish, and as they escape from each nucleus, form a
k ind o f orifice for themselves, those at first protruded serving for a mar-
