Morphology
The compound 'brain mushroom' is directly compositional: 'brain' describes the shape/appearance and 'mushroom' names the organism, so a B1 learner who knows both words can infer it denotes a mushroom that looks like a brain. Shape-based noun-noun compounds are common in English (and other languages), following regular composition patterns, making the meaning readily derivable from the parts.
Etymology
Brain mushroom comes from the mushroom's cap, which is wrinkled and looks like a brain, so people started calling the mushroom by that name. Because this mushroom is 'poisonous', the name also helps people remember not to eat it.
