Black Dots On Bamboo Stalk

Question

The stalk, up to 4 ft, is covered with black spots that get denser and slowly cover most of the surface. Does anybody recognize what is causing this problem and how to address it? The leaves above look green an healthy. Please, email me if you have any information. Thank you.
