Assessment Notes
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.
