Edible portions
- fruiting bodies
Absence of a portion from this list means it is not treated as food here — not that every other part is toxic.
Growing
- Climate. Industrial/compost cultivation
- Light. Dark/shade houses
- Soil. Composted substrate, not garden dirt
- Planting. A specialized craft. Buy them if you want dinner tonight.
- Harvest. Buttons closed; portobello fully open with developed gills.
Preparation and culinary uses
- Cook; they brown and give up water
Safety
- Wild Agaricus includes yellow-stainers that make people sick. Grocery A. bisporus is the food.
