Assessment Notes

Justification

Aside from the type collection of this species, made over 100 years ago, no collections have been made, nor observation recorded. Due to a deficiency in information regarding the distribution of this species, as well as information regarding its habitat preferences and potential threats, this species is listed as Data Deficient until such information arises.

Taxonomic notes

From investigation of the type, this species is a small agaric, not a chanterelle (I. Olariaga Ibarguren in litt. 2022).

---

Geographic range

The only known record of this species appear to be its type specimen, which was collected from Mount Canlaon on Negros Island, Philippines, at an altitude of 2,000m (Bresadola 1912).

---

Population and Trends

The current status of this species' population is uncertain at this time, and its trends cannot be confirmed without further research.

Population Trend: Unknown

---

Habitat and Ecology

Precise information on the habitat type of this species is deficient, however given its named locality and altitude, it is reasonable to assume that this species was found within the tropical montane forests.

---

Threats

If wild subpopulations of this species do exist within its known locality, they could be threatened by volcanic eruption.

---

Conservation Actions

At this time, no conservation action can be recommended without further research to confirm existence of this species in the wild. Much further research is required in order to confirm the existence of any wild subpopulations of this species at its only currently known locality, as well as to assess the threat of volcanic eruption and any other threats which might be affecting this species.
