[2] These microlichens form very thin layers on the surface of leaves, appearing to the naked eye as small, fuzzy dark patches due to their numerous short black bristles.

It is named in honour of Augusto Chaves Batista, a Brazilian mycologist known for his research on tropical fungi and lichens, particularly those in the family Gomphillaceae.

The genus was created after molecular studies showed that these species were distinct from Tricharia, where they were previously classified.

While they share some features with Tricharia species, Batistomyces can be distinguished by its uniquely dense arrangement of short, stiff black bristles on its surface.

Their reproductive structures (apothecia) are translucent and either sit directly on the surface or are slightly elevated on very short stalks.
