Lawreyella was established by Flakus et al. (2019b) to accommodate L. lobariella, originally described as Unguiculariopsis lobariella, which grows on the thallus of Lobaria erosa. Phylogenetic analyses based on SSU-ITS-LSU sequence dataset placed this genus within Cordieritidaceae. The genus is characterized by black, aggregate ascomata with a greenish pigment in the hymeniu and an additional orange-brown pigment in the exciple and epithecium. It possesses short, aseptate, acute excipular hairs. The asci are 8-spored, functionally unitunicate, clavate with a long stalk, and have a slightly thickened apical wall. The ascospores are hyaline, simple, straight to curved, narrowly ellipsoidal with acute ends, and lack of a perispore (Kondratyuk et al. 1995b).

Type species: Lawreyella lobariella (S.Y. Kondr. & D.J. Galloway) Flakus, Etayo, Kukwa & Rodr. Flakus, on Lobaria erosa (Flakus et al. 2019b).

= Unguiculariopsis lobariella S.Y. Kondr. & D.J. Galloway (Kondratyuk et al. 1995b).

Other accepted species: Species Fungorum – search Lawreyella.
