Definition: In linguistics, a polysporum is a type of spore that occurs in fungal spores. A polysporum is a spore with multiple layers of spores, each layer containing multiple spores. These spores are often associated with fungi and can be used to identify the species of fungus they belong to. Polysporums are commonly found on the surface of certain types of fungi, such as mycelium, hyphae, or spore hyaline spores
