is associated with beech and appears to be present in most of the major forests that have retained a healthy population of mature trees.
While large and easily detected, because of the broad distribution of its host there are probably many unrecorded sites. It is estimated that there are up to 500 sites distributed throughout its range, each with a small number of individuals, resulting in an estimation for the number of mature individuals to be up to 3000. There are localised threats to the habitat, but overall the habitat is stable.
It is therefore assessed as Least Concern.
is a New Zealand endemic, occurring on both main islands, found in most major concentrations of beech (Nothofagaceae) forests. It has been collected from January through March, significantly earlier than most other macrofungi in New Zealand.
Population and Trends
There have been thirty records of Bondarzewia kirkii spread over both islands of New Zealand and it is present in most of the major concentrations of beech forest. There have been increasing records in the past 5 years, but these reflect increasing survey effort rather then an increasing population of the species. The greatly increased number of recorders using the i-naturalist app on this showy fungus is the main cause of the increase.

Habitat and Ecology
is a parasitic fungus that fruits on the roots of beech trees throughout New Zealand. It appears to be long lived and to fruit on mature trees. It only has been collected from January through March, significantly earlier than most other macrofungi in New Zealand.
Beech forests are almost all protected in New Zealand through designation as national park or scientific reserves. As such they are not under threat from land use change. Many of these forest have been logged in the past and the distribution and frequency of the fungus may be related to the age structure of the forest. The quality of many forest habitats is however deteriorating due to selective grazing by feral animals, notably deer and pigs. This has affected regeneration in some areas. Increasing periods of intensive drought, and tree windfall resulting from stronger winds, seem to primarily affect older trees that are the hosts for this fungus.
Recognition of this fungus in the management plans for National Parks might help ensure its long term security.
Use and Trade
Sporocarps of the species are occasionally collected in error, by people mistakenly assuming it is an edible Laetiporus
