First described in 1817, the genus consists of crustose and squamulose lichens with green algal photobionts, biatorine apothecia, colorless, simple to 3-septate ascospores, and bacilliform pycnospores. According to the Dictionary of the Fungi (10th edition, 2008), the genus contains 42 species that are widely distributed in temperate areas.

Species

The taxon Biatora marmorea, found in Alaska, was proposed as a new species in 2020; however, it is an illegitimate name as it had already been used for a species that is now known as Bagliettoa marmorea.
