Need help with this one please

Two plants, no tags, not familiar....  Anyone?
 
What is this one???? Dark green ripening to dark/black brown. Dry, not waxy, crisp

It's an annuum, New Mexico type, although short for a New Mexico variety - maybe a cross. Do you have a ripe one? What color is it?

"Chilhuacle Negro"  for sure, i think this is one of the peppers used to make mole
they are probably not very hot
