Absconditella sphagnorum Vězda & Poelt

A lichen typically found in raised bog with a well-developed microrelief of shallow wet depressions and hummocks of drier peat moss. It preferentially grows on various species of living Sphagnum on hummocks. However, its occurrence is seasonal, uneven throughout the year. It can also occur on other substrates: on other species of mosses, liverworts, detritus, pure peat or water-soaked wood. Moreover, A. sphagnorum may be found in other habitats, such as transitional peat bogs, boggy pine forests, or even in open primeval mountain mixed and coniferous forests, where its usual substrate is slowly decaying, lying, water-soaked wood. An exceptional occurrence is the finding of this species in the Karlštejn region on a slowly decaying trunk in a fragment of a relict pine. It is an arcto-boreal species of the northern hemisphere with occasional occurrence in temperate forest types. A. sphagnorum is a type species of the genus Absconditella.
