What causes black stool?

Hello, I have concerns regarding dark green colored, almost black stool I have to go poop 2-3 sometimes 4 times in few hours of waking up but I dont need to go rest of the day usually I do feel itchyness in Anus/rectum area, sometimes burning sensation. I don t have any difficulty passing bowel, I am not constipated and usually not thick in texture. I wonder what causes it? Should i be concerned?

recommend you to have:
1. stool test for occult blood
2. CBC
3. if your age is >55 , then endoscopy

further course of action maybe advised subjected to test results.
