Vernacular names
Tuckermanella is a genus of lichen-forming fungi in the family Parmeliaceae.[1]
Taxonomy
The genus was circumscribed in 2003 by lichenologist Ted Essingler to contain cetrarioid lichens previously placed in the "Cetraria fendleri" species group. The genus names honors the American lichenologist Edward Tuckerman.[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. They proposed to synonymize Tuckermanella with Nephromopsis, along with several other Parmelioid genera, so that all the genera within the Parmeliaceae are about the same age.[3] Although some of their proposed taxonomic changes were accepted, the synonymization of the Parmelioid genera with Nephromopsis was not accepted in a later critical analysis of the temporal phylogenetic approach for fungal classification.[4]
