Alyxoria wainioi


Alyxoria wainioi is a species of lichen in the family Lecanographaceae. It was originally formally described by Finnish lichenologist Edvard August Vainio in 1901, as Opegrapha ochracea. Vainio identified it as a new species from samples collected in Africa by the Austrian botanist Friedrich Martin Josef Welwitsch. However, this name was not validly [published name|validly published] as it was an illegitimate homonym; in 1824 Johann [Adam Philipp Hepp] had transferred Arthonia ochracea, a lichen originally named by Léon [Marie Dufour] in 1818, into genus Opegrapha, and thus the name Opegrapha ochracea was already occupied by this taxon. So in 1923, Alexander Zahlbruckner renamed Vainio's taxon as Opegrapha wainioi. Nearly a century later, it was transferred to genus Alyxoria in 2018 by Indian lichenologists following a revision of the genus Opegrapha.
