Schizophyllum amplum
Schizophyllum amplum is a species of fungus, also known as poplar bells. It is a small inedible bell-shaped fungus that grows from September until November, with a cap sized between 5–15 mm. The fungus grows on fallen branches of a number of hardwood trees. It was transferred to the genus Schizophyllum in 1996 by Karen K. Nakasone as a new combination after a study of Auriculariopsis albomellea and Phlebia albida .

It is common in Europe but found across the world including the United States, Netherlands, France, Spain, Romania, New Zealand, Canada, Austria, Germany, Hungary, Yugoslavia, Russia, Iran and Denmark.
