Infundibulicybe geotropa, commonly known as the Trooping Funnel, is a mushroom characterized by its funnel-shaped cap and pale coloration. It is often found in groups, hence the name 'trooping'. While not considered highly toxic, it can cause gastrointestinal upset in some individuals. Identification can be challenging due to its variability and similarity to other species.
