Ochrolechia microstictoides Räsänen
Thallus thin, somewhay waxy, greyish white, extensively and coarsely greyish-sorediate; apothecia rare. Predominantly northern and western, frequent on base-poor rocks and acid tree bark, but not easily distinguished from O. turneri, which initially has delimited soralia and is widespread, mostly on nutrient-enriched bark.
