Taedigera

Taedigera is a genus of lichen-forming fungi in the family Teloschistaceae. It comprises 6 species. The genus was established in 2024 to accommodate a group of twig-dwelling lichens previously misplaced in the genus Marchantiana, from which they were separated based on molecular evidence and chemical differences. Taedigera species are characterised by their small orange to orange-red fruiting bodies and distinctive chemistry dominated by the anthraquinone pigments parietin or emodin. These inconspicuous lichens typically grow on the slender twigs of shrubs and trees in cool, open habitats such as riverbanks, coastal scrub, and subalpine shrublands. Taedigera is a cool-temperate, Southern Hemisphere lineage: species occur in southern Patagonia (with records from the Falkland Islands), New Zealand, and Australia....read more on Wikipedia.
