Morphological characteristics of colony development in Micromonospora chalcea

Colonies of Micromonospora chalcea display two types of mycelia. Vegetative mycelia are nonbranched, have a propensity for parallel disposition, and possess infrequent septa. The reproductive mycelia develop on their apical portion and are characterized by branching, frequent septation, and bearing of spores that are either sessile or at the end of small sporophores.
