| Comments: | Corsi's locality is not confirmed but is probably correct. Jervis (1889) describes a number of black or blackish limestones from the Province of Como including a compact black marble of Upper Triassic age from Olcio used for decoration in the Duomo in Como. Nero di Como has been used in many Italian churches and cathedrals. |
