I had the same experience earlier this year with C. moorei seed - a bumper season but many of them turned black and shrivelled.  They seemed to be infertile - there was no sign of a radicle wanting to emerge anywhere around the seed.  The seeds that did germinate had no black on them, and have grown very well with no sign of any kind of fungus infection.  If it happens again I'm going to cut them open to see where the black starts and whether there is an embryo or not.
