Morphology
The noun phrase is compositionally transparent: a B1 learner who knows 'beard' and 'lichen' can infer it refers to lichen that looks like a beard (i.e., hanging, tufted). This appearance-based compound follows ordinary English noun‑noun formation and is cross‑linguistically plausible, so its meaning is readily derivable from the parts.
Etymology
Beard lichen comes from a simple image: long, thread-like lichen hangs from branches like a shaggy beard. So the name means a greenish-grey growth that 'hangs from trees'.
