Hydnum
Hydnum is a genus of fungi in the family Hydnaceae. They are notable for their unusual spore-bearing structures of teeth rather than gills. The best known are the edible species Hydnum repandum and H. rufescens. There are no known toxic varieties of Hydnum. Widely regarded as important maintainers of forest ecosystems, the Hydnum genus is known to have ectomycorrhizal relationships with multiple plant families. Hydnum has many brittle, white teeth from which the spores drop. Some species have teeth which hang from ascending branches, while other species have teeth which project downwards from the undersurfaces of dead wood. Most Hydnum species are safe to eat, and contain many fatty acids and antioxidants.
