Seems always to grow associated with the type, of which it is probably
to be regarded onlv as a state, since at times similar conditions occur m
tbe variety. The 'fibrillæ are usuaUy very few, though occasionally
they are more numerous.

priority ; b u t I have retained th a t of Acharius in order to prevent

Differs in the very prominent reticulate rugæ of the upper surface,
which are nearlv a line in height, and which “ look like a series of erect
curled squamules” sometimes developing into small lobules. These
occur chiefly towards the centre of the thallus (except in smaller plants),
bevond wbicli it is usually very rugose, “ almost papillose. To this
latter state belongs var. mesenteriformis (non Wulf. nee Schær.), lu ro .

are sparingly fertile.

AA’ell distinguished from the type by the absence of reticulate plicæ.
In the few British specimens tbe under surface and tbe margins are more
or less fibrillose, so that in this respect they are analogous to form fim -
bnata of the type. I t somewhat resembles G. arctica, but at once diflers
in tbe .smaller and thinner thallus. The apotheoia are numerous, though
small, in our specimens.
