The following fungal species were assessed in 2019 by the International Union for Conservation of Nature and are now part of the global Red List of Threatened Species for Australia:
- Vermilion Grisette – Amanita xanthocephala – Least Concern
- Antrelloides atroceracea – Vulnerable
- Auriscalpium sp. nov. ‘Blackwood’ – Endangered
- Austroboletus viscidoviridis – Vulnerable
- Bondarzewia retipora – Vulnerable

Conservation of fungi is important and, through our work with Lost Fungi, we hope to encourage you to learn about local fungi that are likely to be rare and threatened. Please record them when you can. This work contributes to the global effort in monitoring biodiversity, particularly that done through the IUCN Red List process.

Associated with grasslands world wide.
THREATS
On a world-wide scale, threats to the species are not sufficiently known. The sites where this species occurs in Europe are threatened mainly by intensification or cessation of grassland management, eutrophication and afforestation.
CONSERVATION ACTIONS
Research on the identity and distribution of M. radiosa as well as on its ecology and habitat requirements is recommended.
