Answer: D. They grow quickly underground.
A hyphae is a long, branching filamentous structure found in fungus species. A hyphae is a part of vegetative growth and a group of hyphae is called as a mycelium. Fungi are saprophytic organisms that means they are dependent upon other organisms such as plants and animals for their food and energy requirements. The fungal hyphae spreads grow quickly underground in order to search decaying and dead remains over which these fungus can feed upon.
