Hypotrachyna afrorevoluta (Krog & Swinscow) Krog & Swinscow

The name reflects the species was described from Africa. Later, it has been realized it occurs also on other continents in areas with rather an oceanic climate. In Europe, the species was not distinguished from the similar H. revoluta in the past. However, H. afrorevoluta differs in having verrucose soralia with rough, granular soredia and longer, shinier, irregularly or non-branched black rhizines that grow also on thallus margins and resemble tiny cilia.

The lichen occurs epiphytically, mainly on branches of deciduous trees, less often of conifers such as larches. Abroad, it has been recorded also on rocks. The species is known from all the neighbouring countries, but from the Czech Republic, it has been first reported relatively recently (Šoun et al. 2017). So far, the data has been collected mainly in the western part of the country, individual records exist also in southern and northern Bohemia. Since this species was not distinguished from H. revoluta in the past, its historical distribution is unknown and the revision of herbarium specimens is needed.
