This species was originally described in 1859 by the mycologists Miles Joseph Berkeley and Christopher Edmund Broome in the British "Annals and Magazine of Natural History".

[1] The original collection was done on the Coed Coch estate in Denbighshire, Wales, which then belonged to the Wynne family.

The entry for the new species explicitly mentions Mrs. Wynne, and so it is clear that the mushroom was named for her and not her husband.

The taste is mild and the smell is pleasant initially (of hay, melilot[5] or bitter almonds[3]) but after a moment it becomes unpleasant (of acid,[3] or a drying facecloth[6]).

[8] This mushroom is widespread from August to January in Europe,[8] and has been reported from Algeria, Morocco,[3] and Texas,[9] but not from other regions.
