This diverse family of brown-rot polypores, typically forming tough, woody, or corky basidiocarps on dead or dying conifer and hardwood timber. Fruitbodies range from resupinate crusts to hoof-shaped or shelving brackets, often with distinctive zonation, thick context, and persistent, long-lived structures. Pores are usually round to angular, sometimes large and irregular in older specimens.
