The crust consists of little round lobed leaves, like those of
L . rudiatus, but somewhat of a more grey hue, as indeed is
the whole plant. The stalks are from one to two inches, or
more, in height, mealy, cylindrical, slender, simple or
branched; the branches awl-shaped, acute, more or less
curved. The cups are scarcely more than a slight dilatation
of the top of the stalk, bordered with a series of small tubercles,
which are sometimes stalked, but more frequently
sessile and confluent, or even forming one continued tubercle,
rendered annular by a small central perforation. We find the
tubercles always scarlet, though inclined to turn brown with
age. The varieties C and F of Dillenius are very scaly. These
are of extremely unfrequent occurrence. B, D and F of
Dillenius, are different species from this; the latter possibly
L . vermicularis, but if so the leaves are misapplied.
