Is Common rustgill Toxic?

Common rustgill is considered inedible due to its bitter taste and potential toxicity. Several species within the Gymnopilus genus are recognized as seriously poisonous. While it primarily grows on conifer stumps, debris, hardwoods, and woodchip, the presence of psilocybin in this particular species remains uncertain. Given this, all fungi in the Gymnopilus genus, including common rustgill, should be treated as toxic to ensure safety.

Toxic Severity

Low to high toxicity

Incubation Period

0.5-6 hours

Poisoning Symptoms

Digestive issues, vertigo, vision complications, blood circulation troubles.

Is Common rustgill Toxic to Dogs?

Some sources suggest that common rustgill contains psilocybin, a compound poisonous to dogs, so it is wise to assume that this mushroom is hazardous to your dog, but probably not life-threatening. Psylocibin poisoning causes, disorientation, salivation, vocalization, and seizures in dogs. Seek veterinary assistance if your dog displays these symptoms. This mushroom grows on dead conifers, so it mainly poses a risk to dogs during woodland walks.
