Morphology of filamentous fungi The filamentous fungi consists of two parts: mycelium and spores.丝状真菌由菌丝体和孢子 组成. The filamentous fungi develop multicellular branching structures known as hyphae菌丝， which are connected filaments of vegetative cells.Integrated masses of hyphae are called a mycelium.分支结构为菌丝，菌丝组成菌丝体 Each hypha is about 5-10 um wide.
