Stock Market Truffles in the world

Black truffle trees

The Tuber melanosporum can be found on hilly terrains, with trees fairly apart from each other which form thin groves with brûlé, circles of burned vegetation around the base of trees.

The ideal soil is gravelly and rich in limestone (permeable) with compact subsoil, which promotes the developments of the tree roots on the surface. It is generally rich in calcium carbonate and poor in organic matter. It must not contain more than 40% of clay, as it will hinder sufficient water permeability.
No more than 30% of the terrain must be covered in trees, shrubs must be scanty or absent and grass practically absent. Light must be able to penetrate easily in order to heat the soil.

The Tuber melanosporum has seven host trees.

Quercus pubescens

Evergreen Oak

Quercus ilex

Turkey Oak

Quercus cerris

Linden Tree

Tilia platyphyllos

Hazelnut Tree

Corylus avellana

Hop Hornbeam
