Assessment Notes

Justification

The species is readily recognised with its dark brown cap and dark volva growing on decayed logs. It is an elegant fungus unlikely to be overlooked. Many of the potential habitats in South-east Queensland have be surveyed by member of the QMS over the past decade. The localities in which it has been found appear to be places where there are well decayed large logs and reasonable humidity.

We think it reasonable to suggest that there might be a further four sites yet to be discovered. The collections made have all been of solitary specimens, but following Dahlberg & Mueller (2011) we postulate that many as 5 mature individuals might be expected at each site. Using these figures it would be classed as vulnerable under B2a. The geographic range (Extent of Occurrence) is 5500 Km2 which also suggests a classification as vulnerable. It also qualifies as Endangered under B2 with the Area of Occupancy being 32 km2 along with meeting the sub-criteria (a) Severely fragmented populations.
The species is assessed as Endangered under C ‘Small population’, with the population being less than 250.


Taxonomic notes


Why suggested for a Global Red List Assessment?

This is a small saprotrophic fungus associated with subtropical rainforests in the Blackall Ranges of South-eastern Queensland. Although its identity is subject to some uncertainty, it is readily recognized and may be a good indicator of forest health and the integrity of forest ecosystems. It occurs mostly in protected areas and should be secure from further urban development. But, even these areas may be vulnerable to chance events such as cyclones and habitat loss due to fires, recreational pressure and urban development.
