A red-fruited Cladonia very similar to the common species C. macilenta. They are distinguished based on the podetium surface; it is corticate or granular in C. floerkeana but finely sorediate in C. macilenta. C. floerkeana is usually richly fertile and there are also small differences in secondary metabolites (Ahti & Stenroos 2013).
It is a primarily terricolous species associated with mineral soil, sand or peat. It also grows on rocks and rarely on wood or tree bases. Its distribution in Europe and the Czech Republic is not well-known because of the common confusion with C. macilenta. The lichen is probably widely distributed but only locally common. In the Czech Republic, it is probable rare, more common only on sandy substrates in western Bohemia.
