Assessment Notes

Taxonomic notes

It was described as Xerocomus roseoalbidus Alessio & Littini 1987 and now accepted as
Pulchroboletus roseoalbidus (Alessio & Littini) Gelardi, Vizzini & Simonini 2014


Why suggested for a Global Red List Assessment?

First observed on the island Sardinia in 1986 it was described as uncommon and growing at the edge of deciduous woods in more open areas in extremely arid climatic conditions. This ectomychorrizal species prefers oaks (Quercus cerris, Q. pubescens, Q. suber, Q. robur) and can be find from the sea level up to submontane areas. The distribution is not well known but the observations are increasing and it results present in various countries in southern Europe. Precise studies must be donebut presumibly the species can be assessed as NT.


Geographic range

The distribution is not well known but the observations are increasing and it results present in various countries in southern Europe.

Habitat and Ecology

growing at the edge of deciduous woods in more open areas in extremely arid climatic conditions. This ectomychorrizal species grows in more open areas or at the edge of woods in extremely arid climatic conditions, prefers oaks (Quercus cerris, Q. pubescens, Q. suber, Q. robur) and can be find from the sea level up to submontane areas principally in the mediterranean zone.


Threats

IThe species has more or less similar habitats and phenolody as Alessioporus ichnusanus assesed as vulnerable (Persiani, 2019 in The IUCN Red List of Threatened Species). In Tuscany (Italy) P. roseoalbidus was assessed as VU (Antonini D., Antonini M. , 2006) because of changing of typical habitat - the woods in the plain - due to agriculture.
The increasing observations in southern Europe brought to increasing knowledge and it can maybe be considered as NT.


Conservation Actions

Limiting agricultural landuse and pine plantations, limiting the spread of exotic trees like Robinia pseudoacacia or Ailanthus altissima.
