Assessment Notes

Justification

Currently known only from the type specimen, there is a great paucity of information regarding the status of Cantharellus hystrix. Due to this, C. hystrix is assessed as Data Deficient.

---

Taxonomic notes

Only known from the type collection, it is probable that Cantharellus hystrix should be placed in Craterellus (I. Olariaga Ibarguren in litt. 2022).

---

Geographic range

This species has only been collected from the Singapore Botanic Gardens (Corner 1966), and is known only from the type collection (I. Olariaga Ibarguren in litt. 2022).

---

Population and Trends

It is not possible to estimate the population size and trend of this species.

Population Trend: Unknown

---

Habitat and Ecology

This species is noted as occurring in 'jungle' at the Botanic Gardens in Singapore (see Corner 1966). Given that its taxonomic position is either in Cantharellus or Craterellus, it is assumed to be ectomycorrhizal, but this would require confirmation.

---

Threats

Without further information it is not possible to identify whether this species faces any threats or not.

---

Conservation Actions

Further research is required to clarify its taxonomic position, as well as to conduct further surveys to locate additional specimens both at the type locality and in the wider region. These can then be used to clarify its distribution range, ecological requirements (including potential ectomycorrhizal hosts), population size and trend.

---

Use and Trade

There is no use/trade information.
