Candolleomyces candolleanus (formerly known as Psathyrella candolleana) is a mushroom in the family Psathyrellaceae.

It is commonly found growing in small groups around stumps and tree roots on lawns and pastures[2] in Europe and North America.

The cap is tan when young,[2] growing to 2–8 cm (1–3 in) in diameter,[4] initially conical, later becoming rounded and finally with upturned margins in maturity.

[5] The specific epithet candolleanus honors Swiss botanist Augustin Pyramus de Candolle.

[6] While it is edible and may have a good flavor, it is not recommended due to its thin flesh, alleged poor culinary value and consistency, as well as difficulty in identification.
