Answer

Brief Explanations:

The two clauses "Bioluminescent, or light - producing, fungi glow all the time" and "but are most easily detected in the dark" are independent clauses joined by the coordinating conjunction "but". A comma is not needed before "but" in this case as the clauses are short and the meaning is clear without it.

Answer:

Bioluminescent, or light - producing, fungi glow all the time but are most easily detected in the dark.
