Fungus, mycorrhizal
Amanita muscaria
Fly agaric
A poisonous ectomycorrhizal mushroom, known to chemists because it concentrates vanadium in its fruiting bodies as a natural complex, amavadin. It is not used in remediation: it is included as a case of selective metal accumulation and as a bioindicator.
How it works
- Mechanisms
- bioaccumulation
Contaminants
| Contaminant | Evidence | What was shown |
|---|---|---|
| Vanadium | survey of wild specimens | Measurements on wild mushrooms, not a remediation trial: in fruiting bodies collected at three distant sites in northern Poland vanadium medians fall in the 50-200 µg/g dry matter range, with similar concentrations in cap and stalk and significant differences between sites. |
| Cadmium | survey of wild specimens | In the same samples cadmium in caps has medians of 10-20 µg/g dry matter, higher in cap than in stalk. |
Limits
It cannot be cultivated without its host tree, is poisonous, and its fruiting-body biomass is negligible against the mass of soil: vanadium accumulation does not translate into an extraction technique. The evidence is observational. The determination of amavadin in this species is described in Braeuer et al. (2021), of which only the title and short abstract were consulted.
