Which of the following correctly describes the relationship between the stolon and hyphae in fungi? a) hyphae produce spores, and the stolon distributes them. b) hyphae can grow to form a stolon above ground. c) hyphae store the spores that are produced by the stolon. d) hyphae are provided structural support by the stolon.

The answer is B. The stolon are hyphae that run horizontally and join one sporangiophore (vertically oriented hyphae with sporangia at tips)  –with rhizoids as the ‘roots’ - with the other sporangiophore in the fungi population. They are analogous to rhizoids in eukaryotic runner plants.   The attached diagram visually demonstrates this description.
