[Difference between Calvus and Congestus ?]

Hi, I have difficulties spotting any difference between cumulus congestus and cumulonimbus calvus. What are they ? I know that calvus is supposed to have a smoother "head" but it does not help me. Can someone show me two pictures showing clear differences ? Maybe that the difference between calvus and congestus are only semantic and that both clouds are almost indiscernible. Thanx !
