FLORA OF FORFARSHIRE.

“ Podetia lax, taper branched, smooth ; granules roundish, 
somewhat cinereous, then flattened lobed and crenulated oli- 
vaceous edged with white; apothecia lateral minute flattish.” 
Abundant on the Sidlaw Hills and Clova mountains, ft. 
rare. 
S. nanum , Ach. 
“ Podetia erect, very slender, fastigiate-branchy, below 
naked blackish, above most delicately pulverulent; granules 
wart-shaped minute pale-greenish five cose. ‘ Apothecia la- 
teral convex.’ 
“ Quite different from all the rest by its floccose granules, 
which are usually ochre mixed with verdigris-green. The 
most typical specimens have the thallus very granular, and 
resemble a miniature of the preceding species.” 
This occurred in considerable abundance on the rocks on 
the north banks of the Isla, a little to the west of the Reeky 
Linn. It is the true plant of Acharius, different from that 
previously considered so, and quite new to our Flora. I first 
detected it on rocks at West Water, on the south banks of 
the Tay, and Mr Babington determined it.
