Examine each mushroom closely, taking note of distinct features like cap shape, gill color, bruising, stem characteristics, and whether there is a ring or volva present. These traits can help pinpoint the species. Mushroom experts caution against touching unknown mushrooms.
For safety, first photograph specimens to aid in identification. Trust your instincts if a mushroom seems hazardous or poisonous. Some distinguishing qualities to look for are a thin, fragile stem, cap or gills tinged yellow, red, or brown, and quick bruising where handled.
Approach identification with care, as many lawn mushrooms have toxic lookalikes.
