Turkey Tail (Trametes versicolor) is the most common polypore, and one of the most common mushrooms, in North American woodlands. It is found on logs and stumps of dead hardwood trees, especially oaks. It is sometimes also found on wounds of live trees. It is rarely found on conifers. It appears in the spring and persists through the summer or fall. The fan shape and concentric rings of contrasting colors look like a turkey tail, giving this mushroom its common name.

Northern Tooth (Climacodon septentrionalis) is a widespread and fairly common tooth fungus. The fruiting body is annual and often massive, up to 20″ tall and 10″ wide. It consists of tight, overlapping layers of shelf-like caps joined at the base by a whitish plate. It lives high on the trunks if living hardwood trees, especially sugar maple. It enters the tree through a wound and causes heartwood rot. It is sometimes found on recently dead trees and stumps but is rarely found on fallen logs.
Northern Tooth is not poisonous but is not edible due to a bitter taste and a tough texture. It has a sour smell when it is fresh, an unpleasant, rancid odor as it dries.
