Dijigiella

Dijigiella is a small genus of bark-dwelling lichens in the family Teloschistaceae. It currently comprises two species. The genus was established in 2017 on the basis of DNA sequence data from Australian material that formed its own evolutionary branch, although later work has suggested that Dijigiella may not represent a distinct lineage and could be better merged with the related genus Teuvoahtiana. Both known species produce small, bright yellow to orange disc-shaped fruiting bodies on tree bark, often growing in dense clusters that are more conspicuous than the thin, greyish thallus beneath them. The genus is currently known only from Australia, where it occurs on the bark of shrubs and trees in open, dry habitats....read more on Wikipedia.
