Taxonomy
The genus was circumscribed in 1956 by Australian botanist James Hamlyn Willis, with Bibbya muelleri assigned as the type species.[2] The generic name honours Patrick Noel Sumner Bibby (1907–1955), a colleague with whom Willis had collaborated, and who had died the year previously.[3]
In 1992, Einer Timdal included Bibbya in Toninia.[4] The genus was resurrected in 2018 after a comprehensive molecular phylogeny of the family Ramalinaceae. The authors transferred several species previously placed in genus Toninia, as well as one previously placed in Bacidia.[5]

Description
Bibbya is characterized by the presence of a reddish-brown pigment in the epithecium (the tissue layer above the asci) and in the rim of the exciple (the ring-like structure surrounding the apothecium). The thallus varies in form from crustose to squamulose or bullate (covered with rounded swellings like blisters). The ascospores range in shape from ellipsoid with a single septum, to filiform (threadlike) with multiple septa.[5]
