S eNT by Dr. Pulteney from Dorfetfhire with the laft. We
do not hefitate to make the L. articulatus fig. 1, and barbatus
fig. 2, one fpecies, the propriety of which was firft hinted by
Mr. Lightfoot in Flo. Scot., and we have adopted the fame
opinion from having alfo examined the fpecimens of Dillenius,
which in this cafe are the original authority. Both are found
hanging upon trees in old woods in England and Scotland,
The barbatus, which is the leaft uncommon of the two, is lefs
tumid, and not always fo full of tranfverfe cracks as the articulatus.
The latter has never yet been found in frudeification
with us, but in the fouth of Europe it bears precifely the fame
tubercles as barbatus, (fee Smith’s Tour V. 1 . 312 and 336),
which are fmall, very convex, rugged, and of a pale flefh-
colour. By thefe tubercles, and the fweliings of the ftem,
(the interftices of which are molt generally cracked, and discover
the central fibre, as in L. plicatus) the fpecies before
us, and its variety, may be eafily known from all others of
the fame tribe.
