Distiuguislied from tbe preceding by the paler thallus, the absence of
isidia, aud the presence of greyish or soi'didh' cæsious soredia. The
thaUus is usually small, and is either strictly mouophyllous or sublobate
at the eircuinfereiice. The fructitication is not kuown ; the parasite
Ahrothallus Welwitzschii, sometimes found on the thallus, might be
mistaken for apotheoia.

Also intimately allied to S. fuliginosa, from which it may be recognized
by the more deeply divided thallus, the narrower lohes whioh are
hitid or trifld towards the e.xtremities, aud the generally more naked or
slight!}’ furfuraceous upper surface. I t is usually a larger plant, and
spreads more extensively over the substratum. AA’ith us it is always
sterile.

Looks intermediate between S. fuliginosa and S. sylvatica, and po.s-
sesses some characters in common, but is distinguished from both by tlie
characters given iu the diagnosis. I t is easily recognized by its fimbriate
margins. I t is met with in a less typical condition, with darker
thallus aud more entire margins. I t has not been seen fertile.
Hab. On mossy rocks and trees in maritime aud upland wooded tracts.
