This lichen inhabits mainly mountain coniferous and mixed forests, also peatland forests, raised bogs and scree surroundings. It forms white to grey-white coatings, often sorediate at least in their centres, on wood and bark of conifers, less often on deciduous trees with smooth acidic bark. The taxon may be easily mistaken for the related O. alboflavescens, which has similar ecology, but whose soralia stay delimited for a long time. It may appear also some sorediate Lecanora species, such as L. mughosphagneti, which can occur even in the same habitats. The most reliable species identification is via TLC. O. microstictoides can be found in most of the boundary mountains of the Czech Republic, in the Brdy Hills, Křivoklát and Třeboň regions.
