Fomes weberianus, 50 years of taxonomic confusion: lectotypification and taxonomic notes.

Fomes weberianus Bres. & Henn. ex Sacc.

The - lineage: multilocus phylogenetic analysis and morphology confirm and in the Neotropics.

Many species of exhibit a high phenotypic plasticity. Hence, particularly among them, the morphological species concept remains difficult to apply, resulting in a currently confused taxonomy; as a consequence, the geographical distribution range of many species also remains very uncertain. One of the areas with a strong uncertainty, as far as morphological species concept is concerned, is the Neotropics.
