LICHEN aero tell us.
Little Sharp-tubercled Lichen-.
CRYPTOGAMIA Algce. *
Gen. Char. Male, scattered warts.
Female, smooth shields or tubercles," in which the
seeds are imbedded.
Spec. Char. Crust scarcely any. Tubercles minute,
scattered, somewhat confluent, black, unequal,
convex, pointed, umbilicated.
Syn. Verrucaria acrotella. Ach. Meth. 123.
C o m m u n ic a t e d to Acharius by his celebrated friehd
Professor Swartz, from whom we also have received a specimen,
which accords precisely with what Mr. Borrer has sent
us on a flint from Sussex.
No crust is discernible, except certain minute black fragments
intermixed with the tubercles are to be considered as
such, but we are rather inclined to believe them young or
abortive fructification. The perfect tubercles are about the
size of those of L: Sckraderi, scattered over the smooth broken
face of the flint, sometimes crowded together, round, with a
little prominence, on the summit of which is a dimple or
orifice.
Acharius hints that it may be the first rudiments of his
Urceolaria fimlriata. We should not have suspected any
such thing; but howeve.r that may be decided by future observations,
we have thought it worth while to publish a figure of
what has no where been noticed but in the work above cited.
