is a mainly Mediterranean species, associated with calcareous Quercus ilex
forests (a few northern outposts in calcareous Carpinus-Quercus
forests) (Schmidt-Stohn et al
. 2016), a forest type with many habitat-specific taxa of Cortinarius
, subgenus Phlegmacium
The Quercus ilex
forests and woodlands have been declining e.g. due to transformation into secondary macchia due to land-use, severe forest fires, and die-back of oak due to Phytophtora
and other pathogens.
The species is estimated to have a total population of 8,000 mature individuals. According to the C criterion (C2 a(i)), the species then assessed as Vulnerable, based on a continuous decline, population size <10,000 individuals and very small/isolated subpopulations.
is a striking, rare species, which has its major distribution in the Mediterranean region from Spain to Italy (Schmidt-Stohn et al
. 2016). The species are recorded from more districts in Spain, from Languedoc in S France and from both the eastern and western side of the Apennines in C Italy. Probably the species occurs also further eastward in the Mediterranean region (these areas are little investigated mycologically). Outside the Mediterranean climate zone(s), the species are recorded a couple of times in southern temperate sites in France and in Germany.
Population and Trends
The population is divided into several subpopulations far from each other, the subpupopulations of this species are usually of less than 50 individuals.
The species is known from approx. 10 sites/localities in Spain, approx. 5 sites/localitites in Languedoc in SW France, two sites/localities in the Apennines, C Italy, as well as three localities outside the Mediterranean region (France, Germany). Altogether approx 20 sites/localities are verified/published (see Schmidt-Stohn et al. 2016). The real, total number of sites/localities of C. splendificus are here estimated to 400. This is equivalent to 8,000 individuals according to IUCN standards (Dahlberg and Mueller 2011).
The decline of the calcareous Quercus ilex forests in the evaluation period (last 50 years or three generations) is estimated to be in the magnitude of 15-20%.
Population Trend: decreasing
Habitat and Ecology
is associated mainly with Mediterranean sclerophyllous Quercus
forests, chiefly calcareous Q. ilex
forests. Some southern temperate outposts are found in xerothermous Quercus pubescens
woodland, as well as in Carpinus-Quercus
stands (Schmidt-Stohn et al
and its habitats (calcareous Quercus ilex
forests) have been declining e.g. due to transformation into secondary macchia due to land-use, severe forest fires, and die-back of oak due to Phytophtora
and other pathogens (Hansen and Delatour 1999, Denman et al
To prevent decline and further fragmentation of calcareous Quercus ilex
forests with good habitat quality, it is important to set aside reserves on calcareous hotspots, housing many rare/threatened, habitat-specific species such as C. aurilicis
, C. quercilicis
, C. humolens
. It is furthermore important to establish also sites with a less strict conservation regime, such as woodland key biotopes, where some non-destructive human activities are accepted (such as non-intensive, closed cutting).
More mapping/surveying and monitoring of C. splendificus
are needed. More data on occurrences in calcareous Quercus ilex
forests of the W Mediterranean region (core region) are needed, but also data from the almost un-explored eastern Mediterranean regions. Finally, more documentation on the degree of decline of the habit itself is needed.
Use and Trade
The species is not used.
