Morphology
rhizoctinia + solani
This is a Latin binomial (scientific name) rather than a compositional English phrase: the full meaning (a fungus species causing black scurf on potatoes) is a technical label not predictably built from ordinary English words. One constituent is non‑English/unknown ('solani') and even if a learner knew 'rhizoctinia' = fungus, the species epithet does not transparently convey the disease or host to a B1 learner, so the expression is not derivable from its parts.
Etymology
Rhizoctinia solani may come from words that mean 'root' and 'of the potato', with Rhizo- meaning 'root' and solani meaning 'potato'. The name fits because this fungus lives on potatoes and makes dark, scaly spots called 'black scurf', so it describes what the fungus does.
