No described toxicity
Described signs
Cultivated mushrooms are not listed as toxic: the ASPCA does not expect problems from mushrooms sold in shops for human consumption, when they are clean and without sauces or seasoning. This does not apply to any mushroom from the countryside, the garden or the park: treat those as toxic until a specialist identifies them, and a photo is not enough to tell them apart.
