Cladonia botrytes (K.G. Hagen) Willd.

A species characterized by corticate non-branched or apically slightly branched podetia with usually composite pale-coloured apothecia (pink-brown when wet, ochraceous to pale brown when dry) on the tops. It grows on slowly decaying coniferous wood, typically on the cut surfaces of stumps or logs but also on old thatchroofs, lying branches or tree bark. Rarely, it may also occur on dying bryophytes and humus (Ahti & Stenroos 2013). Cladonia botrytes is a typical boreal-montane lichen, abundant in northern Europe. In central Europe, it is currently considered rare, mainly growing in high mountains. In the Czech Republic, scattered distribution from lowlands to mountains was recorded in the past (Černohorský et al. 1956). The latest record comes from the 1990s from the Šumava Mts (Liška et al. 1998). It has not been found since then, although its presence here is still possible. The species evidently declined and the reasons are not clear but may be linked to, e.g., changes in forest management (Liška et al. 1998).
