Page number:336 
Remarks (public):The genus is characterized by its perennial or long-lived fruitbodies with a distinct cuticle or crust which develops from the base. Its closest relatives are Trametes and Coriolopsis, which both share the same type of hyphal system and spores. However, in both these genera the fruitbodies are short-lived and in many cases covered with a tomentum even if there are species within both genera where a thin reddish cuticle develops from the base. The colour of the context in some Fomitopsis species develops with age and the skeletal hyphae are only weakly tinted. Its woody hard fruitbodies with a cuticle usually make the genus easy to recognize in the field.
