EDIBLE when very young but generally avoided: Only the tender growing edges of very young specimens are palatable - most of the fruiting body is too tough to eat even when young. Strong musty smell and fibrous texture make it unappealing. Can cause digestive upset. Must be cooked thoroughly. Generally not worth harvesting due to toughness. Better polypores exist for eating. Some people powder dried specimens for flavoring.
Massive rosette of large overlapping fan-shaped caps 4-12 inches wide, total fruiting body can reach 12-36+ inches across. Cream to tan to light brown upper surface with radial wrinkles. White to cream pore surface. Thick, tough, fibrous texture even when young. Individual caps larger and less organized than Grifola. Can weigh 20-50+ pounds. Strong musty odor.
