Also intimately allied to 8. fuliginosa, from which it may be recog- 
nized by the more deeply divided thallus, the narrower lobes which are 
bifid or trifid towards the extremities, and the generally more naked or 
slightly furfuraceous upper surface. It is usually a larger plant, and 
oir more extensively over the substratum. With us it is always 
sterile,

Looks intermediate between S. fuliyinosa and S. sylvatica, and pos- 
sesses some characters in common, but is distinguished from both by the 
characters given in the diagnosis. It is easily recognized by its fim- 
briate margins. It is met with in a less typical condition, with darker 
thallus and more entire margins. It has not been seen fertile. 
Hab. On mossy rocks and trees in maritime and upland wooded tracts,

of Scotland (less typical), and S,W. Ireland.—B. M.: Near Torquay, and
