Hyperphyscia adglutinata (Flörke) H.Mayrhofer & Poelt
Thallus foliose, minute, lobes c. 0.5mm in width, appressed to substrate, grey-green, green when damp, more brownish when dry, dotted with tiny, conspicuously paler, convex soralia; apothecia brown with thalline margins, but rare and with spores generally remaining immature. Widespread and locally common, more so in the south, in sheltered depressions and crevices on nutrient-rich bark and more rarely on rocks. Often first noticed by its dot-like soralia.
