On branches.
Perithecia about 12 together ; tbeir ostiola minute, black, in a small flat
disc, which is not raised above tbe bark. Pustules on tbe same branch bursting
tbe bark transversely or longitudinally, sometimes three or four are confluent,
giving tbe plant altogether a different babit.'—M. J .B .

On hornbeam. Dec.
Concealed by the cuticle : perithecia globose, collapsed, circinating, about
eight in a group, with straight decumbent necks and confluent ostiola ; asci
clavate ; sporidia biseriate (’OOOZ-’OOOS in.) ’0177-’02 m.m. long, uniseptate,
constricted strongly at the septum and in the centre of each of the binucleate
articulations. Somewhat resembles the fruit of V.faginea, but is larger and
more constricted.— B. 4 Br.

Remarkable for the green disc above the perithecia. Mr. Currey’s plant
does not appear to differ speoifically from th a t of Tulasne.

On Hawthorn.
Sporidia (’0006-’0010 in.) ’015-’025 m.m. long. Of this species Messrs.
Berkeley and Broome observe th at Mr. Currey’s figure of the sporidia accords
with what they have seen in the early stage of growth, but at length they
are strongly constricted, uniseptate, with two distinct nuclei in each articulation.
