Botryolepraria
Botryolepraria is a genus of saxicolous, byssoid lichens of uncertain familial placement in the order Verrucariales. It has two species. Both species grow in damp conditions, such as on cave walls, particularly in areas with minimal light.
Taxonomy
The genus was circumscribed by Antonio Canals, Mariona Hernández-Mariné, Antonio Gómez-Bolea, and Xavier Llimona in 1997, as a segregate of genus Lepraria, with the widespread and common lichen B. lesdainii as the type, and at that time, only species. The type specimen was collected by French lichenologist Maurice [Bouly de Lesdain] from a wall in Les Baraques. The genus name combines the Greek-derived botryon with its namesake genus, Lepraria.Although some later authors did not accept the proposed genus as different from Lepraria, later molecular analysis showed it to be genetically distinct. Although presumed to be a member of the Lecanoromycetes, its precise classification was not clarified. The genus has been subsequently been accepted by most lichenologists, and is considered to be a member of the Verrucariales with uncertain familial placement. A second species, found in the Neotropics, was added to Botryolepraria in 2010. Both species have similar morphology and secondary chemistry.
