Morphology

Ustilago + maydis

This is a Latin taxonomic binomial rather than an English compositional phrase; the parts are proper names (one a genus label and the other not defined) and do not convey the common-language meaning 'a fungus that causes corn smut.' Taxonomic names are arbitrary and not semantically transparent to an average B1 learner, so knowing the constituent forms would not allow them to infer the MWE's meaning.

Etymology

The noun Ustilago maydis may come from old Latin words: Ustilago from a word meaning 'to burn' because the fungus makes black, soot-like patches, and maydis from the word for 'maize' meaning 'corn'. So the name points to the black fungus that grows on corn.
