Morphology
Peronospora + hyoscyami
This is a Latin binomial (genus + species): if a learner knows 'Peronospora' as a fungal genus they can infer the phrase refers to a species of that fungus, so part of the meaning (a fungal organism) is compositional. However, the species epithet 'hyoscyami' is obscure/non-dictionary and the specific host/disease information (downy mildew on tobacco) requires specialist knowledge, so the full meaning is not predictable for a B1 learner.
Etymology
Peronospora hyoscyami gets its name from the soft, grey 'down' it makes on leaves and from the plant name it was first linked to: Peronospora marks a group of 'downy' fungi and hyoscyami points to the host plant. So the name means a fungus that causes 'downy mildew' on tobacco plants.
