In the most common type of fungal nail infection, distal subungual onychomycosis, infection starts at the end of the nail bed, and part of the nail often turns yellow or white. Pieces of skin and nail fragments (debris) build up under the nail. As the condition gets worse, the nail may crumble and split and may separate from the skin.
