consent, now combined with it again. Mr. Borrer goes farther
and unites with it the Genus Endocarpon, and even thinks that
the Acharian Porina (Pertusaria, DC.) should not be kept distinct.
His character, as given in the Supplement to E. Bot., runs
thus ; " Tubercles of a different substance from the thallus, simple,
convex, not expanding, but furnished with a central pore and
inclosing a somewhat gelatinous nucleus"
* Growing on the bark of trees, Corticolse.

marked with minute pale dots and swelling about the tubercles,
apothecia rather large hemispherical black immersed, at length
partially exposed. Borr.— Schrad. in Journ. 1801, fuse. I. p. 79.

Trees in Ireland; near Bantrv, Mus Hutchins, and near Killarney,
Sir T. Gage, Hart.— Miss Hutchins observes that the living plant is constantly
suffused with a reddish tinge, probably of an extraneous nature,
of which some traces remain on "Mr. Borrer's long-dried specimens.
" Allied, at first sight, to V. epidermidis as it usually grows on Birch-trees,
or to a variety of it which spreads over the trunks of young Ash-trees
but in the real nature of the crust it more resembles V. nitida, although
not in the structure of its tubercles, the shell of which does not, as in
that, inclose the base of the nucleus; but the colour and remarkable
vellum-like appearance of its thinner and polished crust and the entire
want of clots distinguish it." Borr.
3. V. cinerea, Vers, (greyish Bark Verrucaria); crust greyish
uninterrupted thin smooth and polished swelling about the
tubercles, apothecia minute convex black protruding- through and
elevating the crust. F.stigmateUa,Ach. Syn.p.89.—Lichen dig-
