Gymnopilus

This impressive mushroom is found growing in dense clusters on stumps and logs of both hardwoods and conifers--and a number of associated species names are found growing in a dense cluster, as well. These species (if they are truly distinct), are all fairly large mushrooms that have orange to orangish brown spore prints, bitter taste, and stems that feature rings or ring zones. The central species name is Gymnopilus junonius, which is the correct name for "Gymnopilus spectabilis," according to the most recent taxonomists.
