Ochrolechia bahusiensis H. Magn.

A lichen from the O. androgyna aggregate that has a relatively thin thallus with tiny pustules and produces fatty acids from the murolic acid group. However, these may be present only in low concentrations and their detection by TLC may be problematic. In the past, the taxon was sometimes referred to as Ochrolechia androgyna C (Tønsberg 1992).

Ochrolechia bahusiensis grows mainly on bark of deciduous wooden plants (often on beech), seldomly also on conifers and wood, in both forest and open habitats at middle and higher elevations. In the central and northern parts of Europe, it is a relatively common lichen (Kukwa 2011). Its distribution in the Czech Republic is not yet mapped in detail. Apparently, the species is sparse in the country, occurring most frequently in sub-mountain and mountain areas.
