Morphology
mushroom-shaped + cloud
The phrase literally describes a cloud that has the shape of a mushroom, so a B1 learner who knows 'mushroom', the adjectival '-shaped' construction, and 'cloud' can directly derive the meaning. The 'X-shaped Y' compositional pattern is common cross-linguistically and follows standard English compounding, making the expression immediately comprehensible from its parts.
Etymology
Mushroom-shaped cloud gets its name from the sight of a huge cloud that looks like a giant mushroom, with a tall stem of smoke and a round top. That's why the phrase describes the big cloud that rises after a 'powerful explosion', especially a 'nuclear bomb'.
