Cladonia transcendens

Cladonia transcendens is a species of fruticose lichen in the family Cladoniaceae.
Taxonomy.
The lichen was first formally described by Finnish lichenologist Edvard August Vainio in the first volume of his 1887 work "Monographia cladoniarum" with the name "Cladonia corrallifera" γ. "transcendens". The type material was collected from Oregon by David Lyall in 1858. In 1898, Vainio raised this taxon to species level.
Teuvo Ahti and Paula Depriest put forth a proposal to conserve the name "Cladonia transcendens" with a conserved type in 2005. This was later accepted by the Nomenclature Committee for Fungi.
