Intrasporangiaceae

Intrasporangiaceae is an actinomycete family. The family is named after the type genus Intrasporangium. The type species of Intrasporangium (I. calvum) was originally thought to form endospores; however, the mycelium of this strain may bear intercalary vesicles that were originally identified as spores. No members of Intrasporangiaceae are known to form spores.
