Morphology
The phrase is a transparent descriptive compound: 'green' (color) + 'mushroom' (the host) + 'pimple' (a small raised spot), so a B1 learner who knows the constituents would readily infer it denotes a small green, pimple-like growth on a mushroom caused by a fungus. This follows ordinary adjectival and noun-compound composition patterns that are cross-linguistically common, making the meaning immediately comprehensible from the parts.
Etymology
Green mushroom pimple names a fungus that makes a mushroom cap look as if a small green pimple has grown on it. So, the picture of a green bump explains why the term means a green 'mold' that 'infects' and makes mushrooms 'unfit to eat'.
