What is "leccinum"

Leccinum is a genus of fungi in the family Boletaceae. It was the name given first to a series of fungi within the genus Boletus, then erected as a new genus last century. Their main distinguishing feature is the small, rigid projections (scabers) that give a rough texture to their stalks. The genus name was coined from the Italian Leccino, for a type of rough-stemmed bolete. The genus has a widespread distribution, especially in north temperate regions, and contains about 75 species.
