CRYPTOGAMIA. ALGAL Lichen. 
Foliage more rigid and more upright than in the L. polyphyllus, the edge less 
regularly scolloped, more black underneath, and thick set with short black 
tendrils. In other respects resembling that, and has like that dots upon 
the leaves, but more distinct. Dill. Plant circular, expanded, thick, some 
inches over, edge curled, irregularly nicked and scolloped. Surface 
wrinkled or plaited, grey white, sprinkled with minute dots, sometimes 
cracked, sometimes powdery, sometimes smooth. Under side very black, 
closely set with short forked tendrils; root central. Hoffman. Fructi- 
Jications numerous, black, and as Dillenius describes them, “ surrounded 
with a margin and tubercled in the centre.” Mr. Relhan. Besides the 
black fibres underneath, it has a central root, which being broken off, 
leaves the bare place figured by Hoffman. 
This last author doubts whether this be the plant of Linnaeus, but I think 
without much reason. Dr. Smith says that L. polyrrhhos and L. velleus 
are one and the same plant.
