T. arizonica T. coralligera T. fendleri T. pseudoweberi T. rickieae T. subfendleri T. weberi Tuckermanella is a genus of lichen-forming fungi in the family Parmeliaceae.

[1] The genus was circumscribed in 2003 by lichenologist Ted Essingler to contain cetrarioid lichens previously placed in the "Cetraria fendleri" species group.

[2] In 2017, Pradeep Divakar and colleagues used a then-recently developed "temporal phylogenetic" approach to identify temporal bands for specific taxonomic ranks in the family Parmeliaceae, suggesting that groups of species that diverged within the time window of 29.45–32.55 million years ago represent genera.

[4] Tuckermanella lichens have small- to medium-sized foliose (leafy) thalli, and are generally brown to blackish-green in colour.

Tuckermannopsis and Melanohalea are similar in appearance, although species in those genera are typically larger and lack the continuous marginal pseudocyphellae.
