Taxonomy

Coccotrema was circumscribed by Swiss botanist Johannes Müller Argoviensis in 1889, with Coccotrema antarcticum assigned as the type species.

In a 2001 publication, Schmidt and colleagues showed, using molecular phylogenetics, that the species then known as Lepolichen coccophorus (the type species of the genus Lepolichen, created by Trevisan in 1853) was nested in a clade that contained Coccotrema species, and so transferred that species into Coccotrema, as Coccotrema coccophorum.[3] However, the genus Lepolichen is older than Coccotrema, and so its name has priority according to the rules for botanical nomenclature. To minimize nomenclatural disruption, Alan Fryday and colleagues submitted a proposal to conserve the name Coccotrema against Lepolichen.[4]
