Hyperphyscia adglutinata forme foliicole.
Thallus very small, 0.2-0.5 across, minute lace-shaped tightly adpressed to the substratum. Apothecia unobserved yet. Rare (or understated), on leaves of Buxus in shaded and humid areas. N.B. Differs from Hyperphyscia adglutinata only by its very small size and its folicolous habitat on box trees.*
