Dune Fibrecap
Inocybe dunensis
The Dune Fibrecap is a small to medium-sized mushroom characterized by its fibrous, often radially streaked cap surface and typically brown to tan coloration. This mycorrhizal fungus forms essential symbiotic relationships with coastal vegetation, particularly helping stabilize nutrient-poor sandy soils through its extensive underground fungal networks.

Species Profile
The Dune Fibrecap is a small to medium-sized mushroom characterized by its fibrous, often radially streaked cap surface and typically brown to tan coloration. This mycorrhizal fungus forms essential symbiotic relationships with coastal vegetation, particularly helping stabilize nutrient-poor sandy soils through its extensive underground fungal networks.
Dune Fibrecap faces significant threats from coastal development, recreational activities, and climate change impacts on its specialized dune habitats. The species' restricted distribution to fragile coastal sand dune ecosystems makes it particularly vulnerable to habitat loss and degradation from human activities and rising sea levels.
Key Facts
Habitat & Distribution
Coastal sand dunes and sandy grasslands near the sea, typically associated with marram grass and other specialized dune vegetation. The species forms mycorrhizal associations with dune plants in these dynamic, salt-influenced environments.
Threats
Coastal development and urbanization
Recreational trampling and disturbance
Climate change and sea level rise
Invasive plant species altering dune vegetation
Sand extraction and dune stabilization projects
