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]

Description

[edit]

This crustose lichen has minute apothecia (fruiting bodies) with 10–12 small, colorless spores per ascus.[2]

Habitat and distribution

[edit]

The lichen is found on the bark of trees in South America and Africa.[6]
