Bibbya
Bibbya is a genus of fruticose lichens in the family Ramalinaceae.
Taxonomy
The genus was circumscribed in 1956 by Australian botanist James [Hamlyn Willis], with Bibbya muelleri assigned as the type species. The generic name honours Patrick Noel Sumner Bibby, a colleague with whom Willis had collaborated, and who had died the year previously.In 1992, Einer Timdal included Bibbya in Toninia. 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.
Description
Bibbya is characterized by the presence of a reddish-brown pigment in the epithecium and in the rim of the exciple. The thallus varies in form from crustose to squamulose or bullate. The ascospores range in shape from ellipsoid with a single septum, to filiform with multiple septa.Species
