[3] Then in 1821 another Englishman, Samuel Frederick Gray published his "Natural Arrangement of British Plants" (including fungi) in which he allocated the species to the already existing genus Gymnopus.

[5][6] In much later work culminating in 1997, Antonín and Noordeloos found that the genus Collybia as defined at that time was unsatisfactory due to being polyphyletic and they proposed a fundamental rearrangement.

[9][10][6][11] This saprobic mushroom grows generally in smaller or larger clumps on leaves or needles in deciduous or coniferous woods and may be found from May to December.

[5] One 1948 paper states that this species generates hydrogen cyanide (HCN) in detectable amounts, suggesting that it is poisonous.

However the same paper lists other mushrooms normally considered edible, such as Infundibulicybe geotropa, as having the same characteristic, so it is difficult to know how much significance to attribute to this observation.
