Name (and meaning of the absence) of the white semicircle at the base of the fingernail? 1 Answer 1. The lighter crescent-shaped part at the base of the nail is called the lunula. It is a normal part of the nail matrix, and indicates nail growth. The faster your fingernails grow, the more obvious the lunula. Absence of the lunula without any other abnormalities of the nail is not uncommon, and while it can indicate anemia or malnutrition, it is often found normally, and with aging. In this case, careful inspection of all the nails will usually reveal a lunula on the thumbs and the fingers closest to the thumb, but a very small or absent lunula on the other fingers.
