aeciospore singular

Morphology

aeciospore = spore (opaque) = aecio + spore

The element 'aecio-' is a specialized combining form referring to the aecium stage of rust fungi and is unlikely to be known by a general B1 learner, so the meaning cannot be derived from 'spore' alone.

Etymology

Aeciospore comes from the scientific name aecium for a stage of a rust fungus and the common word spore, meaning a small reproductive cell. So an aeciospore is simply a spore made during the fungus's aecium stage.
