Stropharia hornemannii, commonly known as the luxuriant ringstalk, or lacerated stropharia, is a species of agaric fungus in the family Strophariaceae. It is found in Europe and North America, where it grows as a saprophyte on rotting conifer wood. The specific epithet hornemannii honors Danish botanist Jens Wilken Hornemann, who made the first scientifically documented collections of the species. It is inedible and may be poisonous.[1]
It is similar to Stropharia ambigua.[2]
