Common Fieldcap
Agrocybe pediadesAlso known as Common Agrocybe, Hemispheric Fieldcap
Common fieldcaps emerge in warm weather after spring and summer rainfalls, popping up across suburban lawns, pastures, and grassy parks. Their smooth, rounded caps begin warm yellow to tan before flattening slightly and often cracking in dry weather. Beneath the cap, attached gills turn from pale clay to dark cinnamon brown as millions of spores mature.

- Why interaction risk is low
- Many wild mushrooms have toxic look-alikes; never eat wild fungi based on app identification alone.
Responsible observation
- Observe Cap Texture: Note how sticky the cap feels when moist compared to dry weather.
- Check Stem Base: Gently inspect the base for tiny root-like strands called rhizomorphs.
