I would see that this way: black stools are often caused by upper GI bleeding causing a form of stools called melena, tarry and smelly in an unforgettable way; that would cover the first 2 rubrics, with the clots meaning that the bleeding is either so abundant, or lower in the GI tract that it did not have time to be completely decomposed in the melena form.
Black fecal would mean, normal stools but of black colour, as if after taking activated charcoal for example.

People who take iron tablets also have black stools so don't assume there is a problem til you ask about meds !
