a genus of fungi belonging to the family Boletaceae

Leccinum 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 http://www.bartleby.com/61/53/S0115300.html (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.
