I understand that conchiodal is the fracture that is curvered but i don't understad the difference between that and subconchiodal?

On the minerals lab backgrounder it talks about fracture. It says that subconchoidial fractures have a rounded breakage surface, and that conchoidial fractures have a rounded breakage surface with faint, concentric striations on it.
