An inconspicuous but characteristic microlichen, described from the Czech side of the Krkonoše Mountains as Catillaria subtilis (Vězda 1961). The species has a relatively wide substrate ecology, similarly as the related F. bouteillei. The two species together with another closely related taxon F. viridisorediata often form „foliicolous“ communities on needles and thin lower branches of young conifers, in both the natural and managed habitats. However, in contrast to the other two species, Fellhanera subtilis occurs also in more exposed habitats at higher elevations, such as mountain spruce forests, where it may be even dominant on twigs of Vaccinium myrtillus.
