Assessment Notes

Justification

This species was initially described as growing in Drummond, Australia, over 150 years ago. Information regarding the specific geographic locations of wild subpopulations of this species appears to be lacking, alongside information regarding its habitat preferences and potential threats. The only recent observation of this species was made in April 2013, within the Arthur Harrold Reserve, Queensland. It is unknown whether any wild subpopulations remain at this species’ type collection site, and whether such subpopulations are threatened. Overall, due to a deficiency in information regarding this species’ habitat preferences, potential threats, and because the only recent collection of this species is accompanied by uncertain geographic information, this species is listed as Data Deficient until further research is carried out in relation to these issues.

Geographic range

The type specimen of this species was initially described as growing in Drummond, Victoria, Australia, although more specific locality information appears to be lacking (Berkeley 1845). An observation of this species appears to have been made in April 2013 at the Arthur Harrold Reserve, Noosa, Queensland, Australia (GBIF 2020).

---

Population and Trends

The only known wild population of this species recorded in recent years exists under protection of the Arthur Harrold Reserve, Noosa. No further geographic information regarding this species is known.

Population Trend: Unknown

---

Habitat and Ecology

This species was initially found growing, ‘on the ground, amongst little twigs’. This species is thought to attach to these twigs using a white anastomosing mycelium (Berkeley 1845).

---

Threats

The increase in fire intensity across forested areas of Australia could potentially be having an impact on this species, but without further information regarding the full range of the species it is not possible to accurately estimate the impact of such a threat.

---

Conservation Actions

Without further research, no conservation actions can be recommended at this time, due to a deficiency in habitat and locality information. Further information into the distribution of this species, its habitat preferences, and whether it is under threat in any wild subpopulations is required in order to accurately classify this species.
