Morphology

eusporangium = sporangium (semi-transparent) = eu + sporangium + eu

Built from the known technical noun 'sporangium' with the Greek combining prefix 'eu-'; the structure is clear to specialists but the prefix is not transparent to average learners.

Etymology

Eusporangium comes from the Greek parts eu- 'true' and sporangium 'spore' and 'vessel'. So a eusporangium is like a 'true spore container' that grows from several skin cells and makes many spores.
