Conocybe (Conocybe)

Conocybe (Conocybe)

Conocybe mushrooms grow commonly in Nova Scotia in pastures or other open, grassy areas. They are often gathered by individuals mistaking them for Psilocybe species. Like many fungi, they rapidly lose moisture and dry out, appearing like any other little brown mushroom.

Conocybe filaris (Deadly Conocybe) is common in Nova Scotia and contains deadly amanitins (cyclopeptides) like those found in the Destroying Angel (Amanita spp.) and can be lethal if consumed.

Although there are a few species of Conocybe that contain psychoactive compounds, most don’t occur in Nova Scotia. The chances that local species can be mistaken for the deadly Conocybe, or may also be poisonous, are high. Refrain from eating any little brown mushrooms, the consequences from a mistaken identification can be unpleasant at best and deadly in the worst case scenario.
