Norrlinia [SEP] parent taxon
Norrlinia
Norrlinia is a genus of fungi in the family Verrucariaceae. Most members of Verrucariales, as in other lichenized lineages, form typical thallus morphologies, including crustose, squamulose, foliose and rarely subfruticose thalli. Four species of Agonimia can form a monophyletic group together with Norrlinia. Finland has 223 species of Polypores, one of which is Norrlinia. Norrlinia decays trees at a fast rate, but is kept under control in Finland and Russia, the two major countries that are known to have Norrlinia.

Taxon in disguise
In bacteriology, a taxon in disguise is a species, genus or higher unit of biological classification whose evolutionary history reveals has evolved from another unit of similar or lower rank, making the parent unit paraphyletic. This happens when rapid evolution makes a new species appear radically different from the ancestral group, so that it is not (initially) recognised as belonging to the parent phylogenetic group, leaving the latter an evolutionary grade.
While the term is from bacteriology, parallel examples are found throughout the tree of
