The lichen was described as a new species in 2017 by André De Kesel and Damien Ertz, from specimens collected in the Democratic Republic of the Congo (DRC).

Unlike other African basidiolichens such as Ertzia akagerae and Lepidostroma rugaramae, which have scale-like growths, S. miomboensis forms a simple crust.

[2] The organism forms a thin, barely noticeable crust containing single-celled green algae that have multiple chloroplasts and a large oil-containing body.

Under the microscope, they show a complex internal structure of fungal threads (hyphae) arranged in distinct layers, producing transparent, elongated spores.

The fruiting bodies emerge halfway through the rainy season, growing on compacted, iron-rich soil, often along dirt roads.
