A white, yellowish to light greyish-white, finely granular crust, recently described from Europe and so far known only in the sterile stage without apothecia and pycnidia. It is an epiphytic lichen that typically occurs on bark of various maple species (especially on Acer campestre and A. platanoides) and old beeches. It generally prefers old-growth forests. The species is abundant in floodplain forests at the confluence of the Morava and Dyje rivers. Bacidia albogranulosa has been collected at middle elevations in scree forests in the Křivoklát region, in the valley of the Dyje and in the Moravský kras karst. It may also be found in mountain scree forests and rarely in beech forests (Šumava, Novohradské hory, Český les Mts). The highest occurrence reported is from Mt Zátoňská hora at the elevation of 1022 m. The so far known species distribution covers central and eastern Europe.
