Endocarpon.} LICHENES. 159
lus of simple depressed cartilaginous peltate roundish smooth
greenish-yellow scales, apothecia immersed their points redbrown
depressed Ach. Syn. p. 98. Schar. Lick. Helv.p. (r2.

On sandstone rocks in Durham, Rev. Mr. Harriman. Near Sheean
Ferry, Ross-shire, Borr. and Hooker. Fissures of rocks, Ardtur, Argyle-
shire, Capt. Carmichael.
11. E. tephroides, Ach. (ash-coloured Endocarpoii); thallus
crustaceous of depressed areolated and separated lobed or angled
glaucous ash-coloured smooth scales the circumference wavy,
tubercles immersed coal-black the apex depressed margined.
Ach. Syn. p. 98. Lichen tephroides, E. Bot. t. 2013.
On the ground at Burgh Head in Stronsa, one of the Orkneys, Borrer
and Hook.— In habit, this species seems to be the connecting link between
our genera Endocarpon and Vcrrucaria. M. Schaerar, in his
" Observationes Critical," refers it to the former.
12. E. fuscellum, (dark-grey Endocarpon); crust smooth
spreading cracked dark grey somewhat pruinose, apex of the
apothecia flat not prominent black. Lichen fusccllus, Turn, in
Linn. Trans, v. 7. p. 90. t. &./. 2. E. Bot. t. 1500.—E. teph-
roides, \3.polythccium ? Ach. Syn. p. 89.
Onthewalls of Gorlestone Church, Suffolk, Mr. Turner, and in similar
situations in other parts of Suffolk and in Norfolk.—Acharius unites
this with E. tephroides, but I think not justly: the colour, form, and
texture are considerably different, and this has still more the habit of a
Verrucaria, than the last.
13. E. smopicum, Ach. (Sinoper Endocarpon); crust spread
ing determinate tumid smooth cracked and tessellated scarcely
lobed of a rusty red, apothecia minute sunk black depressed in
tin- centre. Ach. Syn. p. 98. Sclurr. Lick. Helv.p, (12. n. 116.
—Lichen sinopietis, E. Bot. t. 1776.
On fellow hone schist, Anglesey, Rev. II. Davis.—This again, like
the last, appears to have as good* a claim to rank with Verrucaria as
with the present Genus. Mr. Turner has suggested that Urceolaria
dianiarta, Acli., is probably no other than this plant : hut Acharius him-
Belfsays that in E. Bot. the lower magnified figure belongs to that plant,
while the upper one is the E.sinopicum. The name, according to Sir
J. E. Smith, is derived from a red stone, called Sinoper, which this
Lichen resembles in colour.
—The Endocarpon paranHeum, Ach. (Lichen parasiticus, E. Bot.
,. 1866,) is i on universal'} considered to he a portion of the thallus of
ParmeUa saxatifo or omphatodet, deformed by a parasite.
