The tuber melanosporum (also known as fine black truffle or Norcia’s truffle or Spoleto’s truffle)
it’s the most precious quality truffle among black truffles.
It grows in sedimentary or gravelly soils, preferring the hardwood as their own symbiont plants.
Like every black truffle, the melanosporum starts a symbiosis with the hosting plant causing the dead of the grass over the roots of the godmother plant. This process is also called “allelopathy” and when it happens to a lot of plants in the same place it takes the name of “Pianello”, this name is commonly used nowadays to call the places where the fine black truffle naturally grows.
Its season in the Marche Region goes from the 1st of December to the 15th of March, while further south, in Abruzzo the season starts 15 days before.
Its name “melanosporum” is due to its black spores (In ancient Greek “melanos” means black and “spora” means seed, spore).
