02Description

Species Profile

Species profile data sourced from the IUCN Red List of Threatened Species.

Vammel tragtridderhat faces severe population declines due to habitat destruction from deforestation and agricultural expansion across its limited range. Climate change is altering the specific soil chemistry and moisture conditions this fungal species requires for fruiting, while overcollection by foragers has further reduced viable populations in accessible areas.
