Taxonomy It was first described in 1970 by Edred John Henry Corner who classified it as Pterula caricis-pendulae.
In 2020 the Pterulaceae family was reclassified based on phylogenetic analysis and many species were split into Pterula, Myrmecopterula, Pterulicium and Phaeopterula genera. This species was one of them and was reclassified as Pterulicium caricis-pendulae by the mycologists Caio A. Leal-Dutra, Bryn Tjader Mason Dentinger and Gareth W. Griffith in 2020.
