Morphology
The compound is a straightforward adjective + noun describing a type of moss with a dark color; a B1 learner who knows 'black' and 'moss' will readily infer it denotes a dark (or dark-colored) moss or moss species. The meaning is compositional and follows a common cross-linguistic pattern of color + noun descriptions rather than any idiomatic or metaphorical shift.
Etymology
Black moss probably comes from the sight of long, dark, hairlike strands that hang from tree branches, with the words black and moss describing how the plant looked; people used this simple image to name it. That's why black moss now means the hanging, grey‑green plant often seen on oaks and used in decorations.
