"Fungal structures" refer to the various cellular and macroscopic components that make up a fungal organism. These can include microscopic structures such as hyphae (long, branching filaments), conidia (reproductive spores), and septa (cross-walls in hyphae), as well as larger structures like fruiting bodies (used for reproduction) and mycelial mats (interconnected networks of hyphae). These structures play crucial roles in fungal growth, development, reproduction, and survival.
