Assessment Status Notes

Taxonomic notes

Why suggested for a Global Red List Assessment?

It is considered as rare or very rare in many European countries although it may be widespread and abundant in certain areas. The fungus is associated with old growth oak and beech woods which in recent years are being eliminated.  In addition its fruit bodies are heavily collected for their culinary value. In 2003 it was red-listed in 13 out of 23 countries in which it had been recorded.

Geographic range

It is mentioned as appearing in many parts of Europe but namely only in central and southern France where it is particularly widespread and abundant, Greece, UK, USA (South Carolina).

Population and Trends

It is considered as rare or very rare in several European countries although it can be widespread and abundant in parts of countries such as central and southern France and South Carolina in the USA…

Population Trend: Deteriorating

Habitat and Ecology

It is associated mainly with living, old, damaged oak and beech trees but it also grows on Fraxinus, .  It also grows on annually pruned Albizia julibrissin trees in urban areas.

Temperate Forest


In Greece, loss of habitat is the main threat.  Old, especially badly shaped oak and beech trees are felled for firewood eliminating suitable trees for the fungus.  Albizia julibrissin trees are infected and killed by Fusarium oxysporum f.sp. perniciosum.  As a result park authorities stopped using this tree in gardens, parks and boulevards.  Its carpophores are heavily picked by mushroom lovers.

Conservation Actions

In 2003 this species was red-listed in 13 out of the 23 European countries in which it had been recorded.  In Greece, there has not been any conservation action so far apart from Informing societies of mushroom lovers about the rarity of the fungus and the threatening factors.
The Forest Service should be informed about the need of conserving old oak and beech woods.
