Galerina marginata
![A group of about a dozen reddish-brown mushrooms clustered together and growing out of a decaying piece of wood covered with moss. The gills on the underside of the caps can be seen, as well as a small ring of tissue on the upper half to third of the whitish-brown stems. Visible amongst the larger mushrooms are about a dozen miniature versions of the larger mushrooms, with hemispherical caps that do not have the gills exposed.](/Images/godic/202501/14/Gifthäublinge1734.jpg")

Galerina marginata is a species of poisonous fungus in the family Hymenogastraceae of the order Agaricales. Prior to 2001, the species G. autumnalis, G. oregonensis, G. unicolor, and G. venenata were thought to be separate due to differences in habitat and the viscidity of their caps, but phylogenetic analysis showed that they are all the same species.
