Candolleomyces candolleanus (formerly known as Psathyrella candolleana) is a species of fungus in the family Psathyrellaceae. The color is tannish when young, fading to white. It is found in lawns in North America.

Description

The cap is tan when young,[2] fading to whitish,[3] and growing to 2–8 cm (1–3 in) in diameter;[4] they are initially conical, later becoming rounded and finally with upturned margins in maturity. The cap margin is irregular and radially asymmetrical—a defining characteristic of this species. It can retain veil fragments on the edge and center.[2] The white stalk[2] is 4–10 cm (1.5–4 in) tall and 3–7 mm wide.[4] The spore print is purple-brown, while spores are smooth and elliptical, measuring 6.5–8 by 4–5 μm.[5]

Similar species

One similar species is Psathyrella gracilis.[4] Some species may have darker caps when young, drying to match that of C. candolleanus.[2] Also similar are C. tuberculatus, Britzelmayria multipedata, and members of Coprinopsis and Psathyrella.[3]

Etymology

The specific epithet candolleanus honors Swiss botanist Augustin Pyramus de Candolle.[6]

Distribution

It is commonly found growing in small groups around stumps and tree roots on lawns and pastures[2] in North America[3] and Europe.[citation needed] In 2014, it was reported from Iraq.[7]

Edibility

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.[2][8][9]
