Assessment Notes

The content on this page is fetched from The IUCN Red List of Threatened Species: https://www.iucnredlist.org/species/154439566/154439652

Justification

This species is currently only known from four records, all of single fruiting bodies. However, it is not possible to estimate the true population size as there is too little information to be able to predict the number of unknown sites at which it may occur. The truffle-like taxa (ex Cribbea) appear to be extremely rare, with only around 40 known collections of the four species. There is insufficient information to be able to quantify any population decline. This species is therefore assessed as Data Deficient.

Geographic range

This species is only known from Australia. There are four records, one in each of North Queensland, South east Queensland, South Australia and Tasmania.

Population and Trends

There are four records, representing four known subpopulations, in North Queensland, South east Queensland, South Australia and Tasmania. This species is recently described so all the observations have been made within the last 20 years. It is thought that each site may actually contain two functional individuals, each representing 2-5 mature individuals, i.e. a total of 16-40 mature individuals at the known sites. Considering the ecological variation in the sites at which it is recorded, it is not possible to estimate the number of unknown potential sites, and therefore the total global population size is unknown.

Population Trend: unknown


Habitat and Ecology

This is a wood decaying fungus that is found attached to buried wood. It is exceedingly difficult to judge its generation length. Reports suggest it is attached to rapidly decaying wood so a 10 year generation length might be appropriate.

The habitat requirements of this taxon are not well documented. It has to be noted that there have not been any repeat collections at known sites. There is some suggestion that it may occur in ruderal sites: it has been found in sandy heath in South Australia, and disturbed parkland in Southest Queensland.

Threats

Land clearance, fire, climate warming and increasingly severe weather events such as droughts and inundations have been identified at all the sites where this species is known. The recreational sites are subject to improvements such as the building of car parks. The type locality has had a toilet block built over it.

Conservation Actions

This species is not protected at any of its current locations. All fungi have been deemed to be least concern as a default position by the Queensland Government.

The biology of this fungus is not well understood, this needs to be clarified both to allow appropriate conservation action to be taken and to focus attention on other possible locations at which it might be found.

Use and Trade

The species is not utilized.
