Morphology
The meaning 'a fungus that causes rust disease' is directly and transparently derived from combining 'rust' (a plant disease producing brown/reddish spots) with 'fungus' (a type of organism). This compositional noun phrase follows a regular and cross-linguistically common modifier-head pattern, so a B1 learner who knows both constituents will readily infer the MWE meaning.
Etymology
Rust fungus gets its name from the rusty-looking red or brown spots the fungus makes on plant leaves. The word rust describes that color and fungus is the living thing, so the name means a fungus that causes a 'rust' disease.
