Surface Forms

promycelium singular

Morphology

promycelium = mycelium (semi-transparent) = pro + mycelium

The segmentation pro- + mycelium is form-meaning transparent in biological terminology, but the precise technical function of the structure is specialized and not directly inferable to general learners.

Etymology

Promycelium comes from pro- 'before' and mycelium 'fungal threads', so it names the short-lived, early thread a fungus grows before it makes spores.
