Black comes at full maturity

Hi, these are certainly Daldinia concentrica or cramp balls. There is confusion if they are called this because they cure or cause cramp. As the previous poster surmised the black colouring comes as the balls are mature.
When dry these make excellent tinder for fire-starting. They should be dried in the open, storing them in boxes or plastic bags causes rotting!
Do remember to take only what you need and never more than 10% of a colony.
