Melanelixia subargentifera is characteristic by soralia on lobe surface and margins and by white-pruina and smooth hairs covering lobe margins. The species grows in open forests, avenues or elsewhere in managed open landscape, typically on trunks of older deciduous trees, mainly ashes, sycamores (Acer pseudoplatanus), oaks and Norway maples (Acer platanoides). Rarely, it may be found also on mossy basic rocks. The lichen is widely distributed across Europe. It has a boreal, temperate to Mediterranean distribution with a continental tendences. It occurs sparsely to rarely from foothills to mountains across the entire Czech Republic. Only in areas most heavily affected by acid rain in the past, the species is still absent (e.g. northern Bohemia).
