[1] Found in the East Province of Cameroon, A. frischii has a smooth, olive-green thallus, and its broadly oval, glass-like ascospores.

However, differences in the ascospores, a crucial feature of lichens, revealed that it was, in fact, a separate species.

[2] In later molecular phylogenetic analysis, A. frischii was shown to be a close relative to the clade containing Diploschistes species.

The unique trait of this lichen lies in its ascospores, which are broadly oval with blunt ends.

At the time of its publication, additional information about the species' distribution or preferred habitats had not been reported.
