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.

Fungal Physiology,Structure,and Symbioses Some fungi produce macroscopic reproductive structures called fruiting bodies子实体 Mushrooms and puffballs are fruiting bodies Fungi can cause disease in plants and animals e Dutch elm trees were devastated by fungal infection of the ascomycete Ophiostoma ulmi Mycoses in humans range in severity from "athlete's foot"to histoplasmosis Chen Feng.Shanghai Jiao Tong University
