What are accumulations of hyphae known as?

Mycelia refers to the network of filaments called hyphae that form the vegetative part of a fungus. These hyphae grow and branch out extensively, creating a complex structure that can spread throughout the substrate or environment the fungus inhabits. This mycelial network is crucial for the absorption of nutrients and is foundational for the life cycle of many fungi.

In contrast, rhizomorphs are specialized structures formed by certain fungi that allow them to transport nutrients over longer distances. Spores are reproductive units that can disperse and germinate into new fungal individuals. Fruits typically refer to the reproductive structures that contain spores, often seen in fungi as mushrooms or other fruiting bodies. By identifying mycelia as the correct answer, it highlights an important aspect of fungal biology that is vital for understanding the role of fungi in ecosystems and their interactions with other organisms.
