Distributed across Australia, India, Indonesia, Japan, and Philippines. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Clustered Pine Bonnet

Mycena stipata, the clustered pine bonnet, is a small saprotrophic fungus in the family Mycenaceae that grows in tightly clustered groups on decaying pine and conifer wood, stumps, and roots across northern Europe and boreal regions. The cap is hygrophanous, grey-brown to tan, broadly bell-shaped, and typically shows lighter tones when dry. The gills are pale grey to whitish, attached to slightly running down the stipe, and the slender stipes are often fused at the base in clustered specimens. Like many pine-associated Mycena species, M. stipata has a characteristic alkaline or bleachy odor and bitter taste. It is distributed primarily in northern Europe including Scandinavia and the British Isles, corresponding to the range of its principal substrate, Scots pine and other coniferous trees. The species is classified as Least Concern by the IUCN. Mycena species play important ecological roles as decomposers of wood and litter in coniferous and mixed forest ecosystems, contributing to nutrient cycling and soil formation. The genus contains hundreds of species, many of which require microscopic examination for definitive identification.
