MSS. (including f. suóciliata, Ny Tt is distinguished by having 
“the thallus suborbicular, somewhat closely appressed, black or blackish

Lichen stictoceros, E. B. t. 1353, — Evernia prunastri, var. gracilis,

stictocera, Ach., is simply E. prunastri typical, with small foreign tubercles 
scattered on the laciniz, a state not uncommon in Britain, and abun aut
