_ OUND on dry expofed heaths in the winter feafon. DiJ-
lenius mentions it as growing near Farnham. Mr. D. Turner
fent it from Yarmouth, and we have gathered it on Moufehold
heath, Norwich, towards Rackheath.
Surety Mr. Dickfon and others, who have placed this Lichen
in the Linnsean divifion of fruticulof, have come nearer the
troth than Dr. Acharius, who has removed it to the fame tribe
with L. corallinus. We venture in this inftance therefore to
diflent from his opinion, and to refer the plant in qtieftion to
his 23d tribe, Cladonia, confiding of L. uncialis, rangiferinus,
and others, whofe bafis is formed of imbricated leaves, which
bear tubular ftalks, fru&ifying at the fummit. The cruft of
L . Papillaria is decidedly fueh, though minute. The ftalks or
ftems ftand more oriels clofely, upright, and are very- fhort,
generally fimple, hollow and inflated. Diflenius and Wulfen
reprefent a more flender and branched variety, which more
nearly approaches the other Cladonia. Round brown folitary
little tubercles terminate each ftem.
We can by no means confider Weber’s L . fragilis a as
having any thing to do with the above, but rather prefume he
intended our fragilis t. 1 1 4 . f . 1 , and has mifquoted Dillenius
and Hallep,
