Molecules are held together by electrons shared between bonded atoms. For example, consider the formation of an H2 molecule from two separate hydrogen atoms: 2 approachinghydrogen atoms(2 H) a hydrogen molecule(H2) As the two atoms approach, each nucleus begins to attract the other atom's electrons.
Definition of Hyphomycetes. in some classifications. : a subclass of fungi coextensive with the order Moniliales or including both the Moniliales and the Mycelia Sterilia.
Structure [edit]. A hypha consists of one or more cells surrounded by a tubular cell wall. In most fungi, hyphae are divided into cells by internal cross-walls called septa (singular septum). Aseptate or coenocytic (without septa). 2  Non-septate hyphae are associated with Mucor, some zygomycetes, and other fungi.  3 Pseudohyphae are distinguished from true hyphae by their method of growth, relative frailty and lack of cytoplasmic connection between the cells.
