Common Fieldcap
Agrocybe pediadesAlso known as Common Agrocybe, Hemispheric Fieldcap
Common fieldcaps pop up abundantly in manicured lawns, pastures, and grassy parks after spring and summer rains. Young caps emerge hemispheric and moist, expanding to a flattened tan or pale yellow-brown disk with attached brownish gills. These small saprobes play a crucial ecological role by decomposing dead root matter and returning vital nutrients to the soil.

- Why interaction risk is low
- Many wild mushrooms have toxic look-alikes; never consume wild fungi based on app identification alone.
Responsible observation
- Inspect cap surface: Note how the slightly sticky top becomes smooth and pale tan as it dries.
- Spore testing: Make a spore print on white paper to confirm its rich brown spore color.
- Check stem base: Look for delicate white mycelial threads clinging to grass roots at the base.
