Assessment Notes

Justification

Estimated area of occupancy 12km2, known from 3 locations with concern over quality and extent of habitat.


Taxonomic notes

In general, Russula species are noticeable but difficult to identify. Russula miniata is recognised because of its small stature, red colouration and association with beech (Nothofagaceaea). The genus has been extensively surveyed and studied in New Zealand over a period of 60 years. This species, and most other New Zealand Russula species are sequence barcoded.


Why suggested for a Global Red List Assessment?

A distinct and uncommon small red species of Russula associated with beech (Nothofagaceae) with at least one population no longer extant.


Geographic range


Population and Trends

Russual miniata is known from just 3 locations and 3 collections.  The population in at least one known site (the type locality) has gone since the 1960s due land-use change. Surveying has not revealed additional populations in this area.

We infer the presence 2 genotypes, x 10 to account for undetected colonies, x 5 to convert to an estimate of 100 mature individuals. Extent of Occurrence 83,000 km2, Area of Occupancy 12 km2

Population Trend:


Habitat and Ecology

Russula miniata is an ectomycorrhizal species associated with southern beech (Nothofagaceaea).


Threats

Of the three known sites the type locality (collection from 1968) has now become farmland, and another modern location is in forest with <10%  protected.
