Galerina patagonica is a species of agaric fungus in the family Hymenogastraceae.

First described by mycologist Rolf Singer in 1953,[1] it has a Gondwanan distribution, and is found in Australia, New Zealand, and Patagonia (South America), where it grows on rotting wood.

[2] The fungus contains a laccase enzyme that has been investigated for possible used in bioremediation of chlorophenol-polluted environments.

[3] The toxicity of Galerina patagonica is unknown.

[4] However, it's phylogenetically nested within the Galerina marginata species complex, and thus likely contains deadly amatoxins.
