Pink earth lichen

Appearance

''D. baeomyces'' is characterized by bulbous pink apothecia, 1–4 mm in diameter, atop stalks no taller than 6 mm. The thallus may be grey or white, and may have a pinkish tinge.

Naming

''D. baeomyces'' is related to ''Icmadophila ericetorum'', the candy lichen, and the two species superficially resemble one another. Its appearance is also superficially similar to some ''Cladonia'' species, particularly ''Cladonia cristatella'' , which has red tips rather than pink; and to multiple ''Baeomyces'' species, which typically have brown tips. ''B. rufus'', as mentioned above, has pinkish bulbs atop its stalks, like ''D. baeomyces'', but like other ''Baeomyces'' species it has been established as not being closely related to ''D. baeomyces''.

Distribution

This lichen is found throughout eastern North America, from Alabama and Georgia in the south to the Arctic Circle in the north. While rare there, it does occur in both Alaska and the Northwest Territories. It prefers to grow directly on unstable soils such as loose sand or dry clay, and in full sun. It also prefers acid soils to neutral or alkaline. On disturbed ground, a preferred habitat type, it is able to spread quickly for a lichen.
