Yellow fieldcap

Bolbitius titubans

A species of Bolbitius. Also known as Egg yolk fungus.

Bolbitius vitellinus, commonly known as the Yellow Fieldcap, is a mushroom species prevalent throughout Europe and North America. It typically thrives in environments rich in nutrients, such as dung patties or heavily fertilized fields, where it prefers to fruit. Its common name is derived from the distinct bright yellow or golden color of its young cap, though this vibrant hue tends to diminish as the mushroom matures and its cap flattens. It's important to note that the Yellow Fieldcap is not considered edible.
