Taxonomy

The genus was circumscribed by Finnish mycologist Otto Miettinen in 2016 with '' Antella niemelaei'' as the

type species In International_Code_of_Zoological_Nomenclature, zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the spe ...

genus '' Antrodiella''. This is reflected in the name ''Antella'', which is a "construct of letters from the genus name ''Antrodiella''."

Description

''Antella'' species have light-coloured, crust-like fruit bodies with a poroid surface. They have a dimitic
