Muhria

About

Muhria is a fungal genus containing a single crustose lichen species, Muhria urceolata. Its family placement is disputed. Broad fungal databases currently accept it in Cladoniaceae, whereas some Nordic and specialist lichen sources place it in Stereocaulon as Stereocaulon urceolatum, usually in the family Stereocaulaceae. The lichen forms a small crust on rock and thin soil, typically among patches of free-living cyanobacteria, and is distinctive for its urn-shaped apothecia that split open by star-shaped slits.
