Habitat of Split fibrecap

The split fibrecap is a woodland species primarily associated with broadleaf deciduous trees, but occasionally with conifers. This fungus exists in a symbiotic relationship with a host tree’s roots, helping it absorb water and nutrients while the tree provides the fungus with sugars and amino acids, and it's always found on the ground, in the vicinity of its host tree's roots.
