The fruitbody is a mushroom, with a cap atop a central stem. The cap is smooth and convex, up to a few centimetres in diameter, some shade of yellow and with a striate margin. The gills are initially off-white but later get pinkish tinges as the spores mature. The stem is smooth, up to a few centimetres long and up to 5 mm in diameter.
There is neither a universal veil nor a partial veil.
Spore print: brownish-pink.
The mushrooms grow from dead wood.
Look-alikes
Some other genera have yellow caps up to a few centimetres in diameter. The closest look-alikes will turn up in the genus Entoloma, because the species in that genus also give a brownish-pink spore print. However, species of Entoloma are very rarely found on wood - and the gills are not free.
Smooth, bright-coloured caps are common in Hygrocybe, but the spore print is white and the fruitbodies don't grow on wood. In Leucocoprinus the caps are scaly or with a granular coating, the mushrooms grow on the ground and the spore print is white.
