Morphology

actinomycete = actinomyces (opaque) = actino + mycete

The immediate base is a scientific genus name rather than a familiar English word, so the structure is not helpful to average learners.

Etymology

Actinomycete comes from Greek parts actino- meaning 'ray' and -mycete meaning 'fungus', because these bacteria grow in long, ray-like threads that look a bit like tiny fungi. So an actinomycete is a kind of bacterium that forms branching, thread-like growths, often in soil.
