Yellow Fieldcap

bolbitius titubans

The Yellow Fieldcap is a bright yellow mushroom that grows in grassy areas. It's fun to spot because its vibrant color stands out against the green grass!

Habitat: Yellow Fieldcaps typically grow in meadows, fields, and grassy areas.

Appearance

The Yellow Fieldcap has a vibrant lemon-yellow cap that often fades to grayish-white at its edges as it matures, appearing like a tiny umbrella. Its cap starts bell-shaped but flattens out, often becoming sticky or slimy when wet, and is very delicate.
