This is one of those situations where a little caution matters a lot.
From the photo, an observations, but not a safe, definitive ID:
They’re white, smooth-capped mushrooms with a rounded “button” shape (one more mature, one younger).
The larger one shows free gills (not attached to the stem) and a veil remnant (that torn edge under the cap).
The stem looks fairly plain—no obvious ring in the photo, but that might just be angle or maturity.
The smaller one has darker gills, which suggests they darken with age.
That combination could point toward something in the Agaricus family (like store mushrooms)…
BUT—and this is the important part—it can also overlap with dangerous lookalikes, especially:Amanita species (some are deadly poisonous, like destroying angels)
Certain white lawn mushrooms that cause stomach upset or worse
Here’s the hard truth:
White mushrooms are one of the most risky groups to guess on. Even experienced foragers treat them carefully because harmless and deadly ones can look nearly identical.
What you should do right now
Do NOT eat them
Wash hands after handling
Keep them away from pets/kids’ mouths
If you’re curious (safe way to learn)
If you want to narrow it down safely, these details help a lot:
Was there a bulb or sac (volva) at the base underground?
Do the gills turn pink → brown (Agaricus trait)?
Any strong smell (chemical, almond, foul)?
Where were they growing? (lawn, wood chips, near trees?)
If you can, snap:
The base of the stem (dug up)
A side view of the gills
The underside clearly
Straight talk
Don’t try to “figure it out enough” to eat. With mushrooms, it’s not like plants where you can take a chance—some mistakes are permanent.
But as a learning moment with the grandkids? This is actually great. You can show them:
“Some things in nature look simple and safe, but you have to slow down and really understand them before you interact.”
