Maronella is a genus of lichens of uncertain familial and ordinal placement in the class Lecanoromycetes.[1] The genus was circumscribed in 1959 by German lichenologist and lichen chemist Maximilian Steiner with Maronella laricina assigned as the type, and at that time, only species.[2] This lichen is rare, having only been recorded from Austria and Spain.[3]M. coreana, known only from type collection in South Korea, was added to the genus in 2015. Both species grow on bark and have a crust-like thallus.[4]
