Cladonia acuminata (Ach.) Norrl.

Cladonia species characterized by thick-walled, usually unbranched pointed podetia with discontinuous cortex and squamulose, but granular-sorediate in the upper part, surface. The primary thallus is inconspicuous, composed of minute, just a few mm large squamules. The most common chemotype in Europe contains atranorin and norstictic acid.

It is a widely distributed bipolar taxon known from both hemispheres and also from tropical mountains. It usually occurs on open stands, on basic soil or humus, in Europe mainly in mountain or northern areas (Ahti & Stenroos 2013). C. acuminata is rare in central Europe, recorded mainly in the high mountain ranges, such as the Alps and the Tatra mountains, exceptionally also from lower elevations. In the Czech Republic, it was historically known from the surroundings of Česká Lípa (Anders 1906) and unspecified localities in Moravia (Kovář 1912). Recently, it has also been found in the sandstone areas of Saxon Switzerland, less than a hundred metres from the Czech border (Palice et al. 2018). The collection represented a rare chemotype containing atranorin and fumarprotocetraric acid previously only known from the southern Hemisphere, specifically from Tierra del Fuego (Stenroos & Ahti 1990).
