“Magic” mushrooms (Psilobyce sp) contain psilocybin and psilocin which are structurally related to LSD and are presumed to act on serotonin receptors. Signs reported in dogs include vocalization, mydriasis, ataxia, tachycardia, disorientation, hyperthermia and anxiety. Rarely tremors and seizures have been reported.
Hallucinogenic mushrooms aren't life-threatening and rarely need treatment. That said, signs of ataxia (acting abnormal, howling, abnormal eye movement and hyperthermia) can be seen when dogs ingest them.

Dogs can eat most store-bought mushrooms. These can include canned, cremini, portabella and shiitake mushrooms. Some mushrooms are as toxic to dogs as they are to humans, but those aren't typically sold in standard grocery stores, as you'd expect.
Grocery store-bought mushrooms are generally safe for dogs to eat, but leave off the sauces, oil, salt and other spices which can be harmful to dogs. Dogs can eat store-bought mushrooms plain or raw, but don't really need them in their diet.
Similar to humans, some mushrooms are fine for dogs to eat, while others can be toxic. Dogs can eat mushrooms bought from a supermarket or other shop, preferably organic, unseasoned and raw. But you should always avoid any wild mushrooms.
As mentioned previously, dogs can eat mushrooms, raw and cooked. They contain vitamins B and D, minerals and antioxidants. They are also low calorie, have no fat or cholesterol and contain very little salt.
More serious symptoms of mushroom poisoning include seizures, coma, liver failure, abdominal pain and death, making it imperative you see your veterinarian or an emergency vet immediately if you suspect your dog got into wild mushrooms.
