Assessment Notes

Justification

Craterellus pulverulentus is a Caribbean fungal species reported only from Cuba and Puerto Rico, with the most recent record of the species published in 1924 (Burt 1924). Without any more recent data it is not possible to accurately assess if it persists at historical localities, and what its current distribution could be. Therefore, it is not possible to accurately assess the extinction risk of C. pulverulentus and it is assessed as Data Deficient.

Geographic range

This species is known from the Caribbean, with the type collection made on Cuba, with an additional collection from "Monte Alegullo" on Puerto Rico under the homotypic synonym of Cymatella pulverulenta (Berkeley and Curtis 1869, Burt 1924). There appear to have been no more recent records.

---

Population and Trends

With no published records of this species for approximately 100 years it is not possible to accurately estimate the population size and trend.

Population Trend: Unknown

---

Habitat and Ecology

This species grows on the bark of sticks (Berkeley and Curtis 1869, Burt 1924), but the general habitat type it is found in was not noted.

---

Threats

Without clearer information regarding the full range of the species it is not possible to accurately assess the specific threats it may face.

---

Conservation Actions

Further research is needed on this species. This should primarily focus on trying to relocate the species and then investigating its habitat and ecological requirements. Its taxonomic position should also be evaluated to confirm its generic position.

---

Use and Trade

There is no use/trade information.
