Teuvoa

Teuvoa is a genus of lichen-forming fungi in the family Megasporaceae. It was first classified by lichenologists Mohammad Sohrabi and Steven Leavitt in 2013, with Teuvoa uxoris assigned as the type species. This genus was delineated from the larger genus, Aspicilia, following a molecular phylogenetic analysis which revealed that the Aspicilia uxoris species group constituted a distinct lineage in the Megasporaceae. Initially containing three species, two additional species native to China were added in 2018. Teuvoa is characterised by its small ascospores and conidia, and the absence of secondary metabolites. The physical characteristics of Teuvoa include a crustose thallus, forming a distinct areolate or patchy pattern, which can range from white to grey in colour with a dull surface. The innermost layer, or medulla, is white. The genus's photobiont, a photosynthesising partner, generally belongs to the green alga genus Trebouxia or similar chlorococcoid genera.
