Allographa aptrootiana

Allographa aptrootiana is a species of script lichen in the family Graphidaceae that is found in tropical Africa. It was formally described as a new species in 2014 by Dries Van den Broeck, Robert Lücking, and Damien Ertz. The type locality is Yaengo excipulum, and does not produce the secondary compound atranorin. The holotype specimen is parasitised with Etayoa trypethelii, a widespread tropical lichenicolous fungus. The specific epithet aptrootiana honours André Aptroot, "in recognition of his many contributions to tropical lichenology". The taxon was transferred to Allographa in 2018 following a reinstatement and reorganization of that genus.
