Gyalecta nana

Lichen species

Gyalecta nana is a species of corticolous (bark-dwelling), crustose lichen. It was first described in 1862 by the American lichenologist Edward Tuckerman.[2] In 1969, Antonín Vězda renamed the genus Gyalectina in an effort to denote its 12–16 spores per ascus in comparison to the ≤ 8 spores per ascus of Gyalecta,[3] and research in 1982 posited that G. nana was synonymous with Cryptolechia nana.[4] In 2019 molecular phylogenetics analysis suggested the most appropriate characterization again was Gylecta nana.[5]
