Infundibulicybe gibba (also known as Clitocybe gibba), and commonly known as the common funnel or funnel cap,[1] is a species of gilled mushroom which is common in European woods.
The epithet gibba comes from the Latin adjective "gibbus", meaning "humped" or "gibbous".
This species was originally described by the mycologist Christiaan Hendrik Persoon in 1801 as Agaricus gibbus, at a time when gilled mushrooms were generally all assigned to genus Agaricus. Then in 1871 in his guide to mycology ("Der Führer in die Pilzkunde"), Paul Kummer allocated the species to the genus Clitocybe, which previously (according to the system of Fries) had only been a tribe within genus Agaricus.
In 2003 Harri Harmaja created the new genus Infundibulicybe for some of the larger members of the former Clitocybe and he included Infundibulicybe gibba as the type species.
Clitocybe catinus is described as differing from C. gibba by having white cap with occasionally some pink tonality and its slight smell of flour.[2]
Harmaja (2003) gave it a new name Infundibulicybe catinus.
Vizzini et al. (2011) listed it a color variant of Infundibulicybe gibba.
The older name Clitocybe infundibuliformis is often identified as a synonym of I. gibba, but according to Species Fungorum that use was incorrect and the original C. infundibuliformis was a different mushroom.
The name infundibuliformis derives from the Latin "infundibulum", a funnel, with the suffix "-formis" - so it means "funnel-shaped".

This gregarious saprobic mushroom grows on soil in deciduous or (less commonly) coniferous woods and may be found from summer to autumn. It sometimes forms fairy rings.
It is very common throughout Europe, and occurs in North America and Japan.
It is edible when young, but said to be of mediocre quality. It can be fried or used in risottos or soups etc. The stems are tough and may be discarded. The species resembles some which are poisonous.
An extract of I. gibba exhibits inhibitory activity on thrombin.
The species resembles Infundibulicybe squamulosa and Pseudoclitocybe cyathiformis.
