gee by Nees and Sprengel, while Dr. Greville's Cldorococcum (a
genus of Algce) vulgare, which he has most judiciously separated
from the PahneUa botryoides, with which it had been
confounded, is the Lepraria viridis of Messrs. Turner and
Borrer. But it appears to have an equal claim to rank with
the other Lepraria' among the Lichens, as with the Alga. No
distinct fructification has been found, and the character of the
Genus Chloroeoccum is in reality the same as that of Lepraria,
"Gratuda omnino libera minima aggregata absque gelallna? If
therefore L. viridis be removed to the Algce, so should the rest of
the Leprarice.

On pales, old buildings, trees and walls, abundant.— The granules are
often clustered together, and Dr. Greville observes them to be so in
fours.—The membranous base to this species, noticed by Sir J. E. Smith,
has not been remarked by other Botanists.
2. L. murdrum, Grev. (wall Lepraria); sporules green sim-
ple minute oval-oblong.— Chloroeoccum murorum, Grev. Scot. Cr.
FL t. 325.
On walls and stones, frequent, Dr. Greville.— This forms small spots
of a yellowish-green colour, the spots at length becoming confluent.
It is so closely allied to the preceding, that whether that be placed
with the Algae or with the Lichens, the present should rank next to it.
3. L. ochrdcea, Turn, and Borr. (peltry Lepraria); crust none,
sporules extremely minute ochraceous-ydlow collected into thin
scattered patches. Turn, and Borr. Lie//. Br. p. 8. E. Bot.
