convex wet than dry; the surface of a very minutely granulated
appearance under a powerful glass; internal substance
rather paler, sometimes with an orange tint, marked,
according to Mr. Sowerby’s observations, with obscure
vertical striae.
It may very reasonably be questioned whether this species
has a just claim to a place amongst the Lichens, and
whether what is taken for its thallus is in reality more
than a discoloration of the bark. Specimens from Acha-
rius, preserved in the museum of the Linnean Society, authorize
the citation of the two synonyms given above.
