TA H IS , though by far lefs common than the preceding, is
found on trees, chiefly in the moft woody and rather mountainous
parts of our ifland. Its near affinity to L.farinaceus has
already been mentioned, but we (hall proceed to {how their
differences. L . fajligiatus is equally tufted and branched,
but generally fhorter, lefs foft and flexible ; its colour rather
more yellowifti, verging towards an ivory hue, though fome-
times (as Dr. Acharius mentions in the Stockholm Tranf-
actions) it becomes afhcoloured; its branches are alfo broader,
and, though pitted, their furface fmooth, almoft {hining,
and always deftitute of the powdery warts or cracks, fo con-
fpicuous in L. farinaceus. The ihields are copioufly produced,
each on a broad bafe, lateral, or moil frequently nearly
terminal, the pointed fummit of the branch beyond them being
more or lefs reflexed : when young they are concave, glaucous
white, with a fmooth acute margin; when older they
become flat or convex, and of a pale buff.
We take this opportunity of correcting an overfight in W . 10 .
t. 688, of this work. Dr. Acharius rightly obferves that L.Jco-
fulorum is the real calicaris of Linnaeus, a fa£t which efcaped
us before, but to which we now fully affent. The calicaris of
Britiffi authors is that now before 11s.
