Austroboletus viscidoviridis

Austroboletus viscidoviridis is a fungus belonging to the family Boletaceae, characterised by the pore-bearing fruiting bodies typical of boletes rather than gilled mushrooms. As with most boletes, the visible mushroom is a temporary reproductive structure produced by an extensive underground network of mycelium, which forms mycorrhizal partnerships with the roots of host trees. This symbiotic relationship allows the fungus to exchange soil-derived nutrients and water for photosynthetic sugars, playing a role in nutrient cycling and supporting forest and coastal vegetation health.

The species is known from Australia, where it occurs in coastal and supratidal habitats. Its distribution appears to be limited, and it depends on the persistence of specific vegetation communities and associated soil conditions found in these coastal zones.

The species faces a range of ongoing pressures linked to human land use and environmental change. Expansion of housing and urban development, tourism and recreational infrastructure, and livestock grazing all contribute to habitat loss and degradation in the coastal areas it inhabits. Road construction and recreational activities cause further disturbance, while broader habitat shifting and alteration, drought, and fire and fire suppression regimes affect the vegetation and soil conditions its mycorrhizal partners require.

Invasive species and associated diseases add additional stress to host plant communities.

No population figures are currently available. The population trend is assessed as decreasing, consistent with the cumulative impact of habitat modification across its limited coastal range. Conservation measures specific to this species are not well documented, though its listing as Vulnerable reflects recognition of these compounding threats.

Its outlook remains uncertain, dependent on the protection of remaining coastal habitat and management of the pressures acting upon it.
