The stalk is undoubtedly hollow in some parts of the gathering, in others 
it is doubtful, but I have referred the specimens to P. antarctica.

For the determination of the Hypogymnia section of Parmelia, Bitter’s 
important paper (01) should be consulted. According to his classification 
the plant which Mrs. Vallentin found so plentifully on Empetrum rubrum 
is referable to P. lugubris rather than to P. enteromorpha. Probably the 
bulk of Hooker's material belongs to the same species, though referred by 
him to P. enteromorpha. 
Several lichens are known to be carried large distances by the wind, 
and Mrs. Vallentin records in her note-book that this is particularly the 
ease in the present specles, owing to the thallus being so much inflated 
with air.
