Rufoplaca

About

Rufoplaca is a genus of lichen-forming fungi in the family Teloschistaceae. The genus is found primarily across the Northern Hemisphere, with most species occurring in Europe and additional records from North America and Asia. These lichens typically grow as thin crusts with orange-red colouration on sun-exposed rocks and other surfaces. The genus was established in 2013 to group together several previously scattered species that genetic studies showed formed a natural evolutionary lineage.
