Ecology, status and trends should be clarified.

Taxonomic notes

Beenakia dacostae is a distinctive species, described in 1955. It is recognisable in the field by the relatively soft sporing bodies, pale pileus, and decurrent, olive-brown spines.

Why suggested for a Global Red List Assessment?

There have been less than 100 sightings of this species. Their habitat is decreasing due to climate change, urbanisation, increased fire frequency, drying forests and deforestation.

Geographic range

Australia: Tasmania, Victoria and New South Wales (one site, rainforest at New England National Park); New Zealand: North and South Island; New Caledonia

Population and Trends

There have been a total of 104 recorded sightings of this species in Australasia. In Australia there have been 46 sightings in Tasmania, 30 in Victoria and one in New South Wales. In New Zealand there have been 21 sightings in the North Island. Data was obtained from the Atlas of Living Australia (ALA) on March 3, 2019. There were many duplicate records which were removed. The species has been observed in New Caledonia, where it appears to be rare (6 sightings).

In Australia, the predominant habitat is Cool Temperate Rainforest, or wet, tall Eucalyptus forest. In New Caledonia, is associated with Nothofagus.

There are large areas of suitable habitat where the fungus has not been recorded (particularly in Australia), and the number of sightings (say 100) would have to be multiplied by 10 or more to account for unrecorded sites. At a given site there is no information as to how many patches might be expected, so we could double the functional individuals to allow for unrecorded individuals at a site level. Assuming 5 mature individuals for each functional individual, gives a population estimate of 10,000.

Population Trend: Uncertain

Habitat and Ecology

On dead wood, often rotten limbs and branches in wet forests. Fruit-bodies are sometimes found in dry, shaded spots beneath very large fallen logs.

Found predominantly in wetter forests including Rainforests and Vine Thickets, Eucalypt Open Forests, Low Closed Forests and Tall Closed Shrublands and less commonly in Other Grasslands, Herblands, Sedgelands and Rushlands, Acacia Forests and Woodlands and Cleared, non-native vegetation areas.


This fungus is found on slopes that are subject to deforestation and urbanisation. Their habitat is wet forest which is shrinking/drying due to climate change. With the Australian forests that being subjected to increased fire frequency and intensity, often resulting in drier vegetation in post fire communities.
