Amanita Xanthocephala colonizes the host plants' roots extracellularly, by doing this it provides Amanita xanthocephala with a relatively constant and direct access to carbohydrates that the plant produces. The carbohydrates are translocated from their source (Photosynthesis) to root tissue and on to Amanita xanthocephala. In return, the plant gains the benefits of the mycelium's higher absorptive capacity for water and mineral nutrients (Because mycelium has a huge surface area), thus improving the plant's mineral absorption capabilities.
Amanita xanthocephala lives in an ectomycorrhizal relationship with Eucalyptus.
Although P. australiana, P. eucalypta and P. tasmania have subtle physical differences, they are mostly the same mushroom with similar alkaloid content.
