Assessment Notes

Justification

The fungus was collected and described by McNabb in 1968. It has been systematically sort in the type locality over a 20 year period and not rediscovered. Similar habitats in the north and centre of South Island have also been extensively surveyed in recent year without result. The species has not been seen for 50 years and it is reasonable to suppose it is extinct.


Taxonomic notes

Lactarius maaruiaensis McNabb


Why suggested for a Global Red List Assessment?

Proposed by Pat Leonard. Known only from the type collection in SI New Zealand. A relatively large member of the L. eucalyptorum group. It has been extensively searched for over a 15 year period, without success. The type locality is subject to increased tourism pressure. AOO/EOO 4 km2.


Geographic range

Springs junction, South Island, New Zealand.


Population and Trends

The population estimate is zero.

Population Trend:


Habitat and Ecology

Lactarius maruiaensis was a mycorrhizal fungus found in Nothofagus forest.


Threats

The area where it was originally found at Springs Junction has undergone rapid land use change with native forest and low intensity grazing being replaced by high intensity dairy farming. The area retained in forest has seen substantial increases in recreational use over the past 50 years. There is some evidence of damage to the habitat by pigs and deer.


Conservation Actions

List as Extinct but continue to monitor the area.


Research needed

None
