Braunnetziger Raukopf
Cortinarius melanotus
Braunnetziger Raukopf (Cortinarius melanotus) is a distinctive mushroom species characterized by its dark brown to blackish cap with a netted or reticulated surface pattern and robust stature. This mycorrhizal fungus forms essential symbiotic relationships with coniferous trees, facilitating nutrient exchange and supporting forest ecosystem health through its extensive underground hyphal networks.

Species Profile
Braunnetziger Raukopf (Cortinarius melanotus) is a distinctive mushroom species characterized by its dark brown to blackish cap with a netted or reticulated surface pattern and robust stature. This mycorrhizal fungus forms essential symbiotic relationships with coniferous trees, facilitating nutrient exchange and supporting forest ecosystem health through its extensive underground hyphal networks.
Braunnetziger Raukopf faces significant threats from habitat degradation and loss of suitable forest ecosystems due to logging, agricultural expansion, and climate change. The species' specialized ecological requirements and dependence on specific host trees make it particularly vulnerable to environmental changes and forest fragmentation.
Key Facts
Habitat & Distribution
This species inhabits mature coniferous and mixed forests, particularly those dominated by spruce and fir trees, typically at montane elevations. It forms mycorrhizal associations with specific coniferous host species and requires undisturbed forest floor conditions with appropriate soil chemistry and moisture levels.
