Common Bonnet - Mycena galericulata
Widespread and common across much of mainland Europe and North America, Mycena galericulata (Mycenaceae) is larger than most of the other tuft-forming bonnet mushrooms that are found on stumps. This species shows a distinct preference for well-decayed moss-covered stumps and fallen trunks of deciduous broadleaf trees. Only very occasionally is this bonnet mushroom found on conifer stumps and fallen trunks.
