Assessment Notes

The content on this page is fetched from The IUCN Red List of Threatened Species: https://www.iucnredlist.org/species/265980062/266021001

Justification

Phaeoradulum guadelupense is a resupinate species from Guadaloupe, described in 1900. Its most recent record is from 1903 making it impossible to estimate the current population size or distribution, so it is assessed as Data Deficient (DD).

Taxonomic notes

Phaeoradulum guadelupense is the only remaining species in the Phaeoradulum genus (Species Fungorum 2023), established in 1900 based on the distinct morphological characteristics of its spores (Patouillard 1900).

Geographic range

This species is only known from Guadeloupe in the Caribbean.

Population and Trends

The most recent record for this species dates from 1903 (GBIF.org 2023). Without more recent observations or information on targeted search efforts it is not possible to estimate the population size.

Population Trend: Unknown


Habitat and Ecology

It is a resupinate species, found growing on decaying stems of Daphnopsis caribaea (=Daphnopsis americana subsp. caribaea per POWO 2023) (Patouillard 1900).

Threats

Threats are unknown.

Conservation Actions

Search efforts are needed to estimate the population size, distribution and habitat preferences. Further taxonomic research is also recommended to clarify its placement within Boletales and confirm this is a monotypic genus.
