Willow Bonnet

Mycenella salicina

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

The Willow Bonnet faces severe decline due to the widespread loss of mature willow woodlands across its European range, particularly from intensive forestry practices that favor monoculture plantations over diverse riparian forests. Climate change compounds these pressures by altering moisture regimes essential for this saprotrophic fungus, while pollution from agricultural runoff degrades the water quality of wetland habitats where its host willows thrive.

Threat summary

Habitat

This saprotrophic fungus is exclusively associated with decaying wood of willow species (Salix spp.) in wet woodlands, riparian forests, and marshy areas throughout temperate Europe. It requires consistently moist conditions and mature willow stands with abundant deadwood for successful fruiting and spore dispersal.
