The Swiss lichenologist Johannes Müller Argoviensis first proposed Phyllobathelium in 1883 as a section of the genus Bathelium. He promoted it to full genus status in 1890.
Description
The main characteristic of the genus is the presence of black, amorphous to pulverulent (i.e., powdery and crumbly) structures on the upper part of the wall of the perithecium (fruiting bodies).
