Cladonia uncialis is a species of fruticose, cup lichen in the family Cladoniaceae. It was first described as a new species by Swedish taxonomist Carl Linnaeus in 1753. ^[2] It was transferred to the genus Cladonia by Friedrich Heinrich Wiggers in 1780. ^[3] In North America, the lichen is colloquially known as the thorn Cladonia ^[4] or the thorn cup lichen. ^[5]

Cladonia uncialis is host to the lichenicolous fungus species Lichenopeltella uncialicola , which is named after C. uncialis. ^[6]
