The white pigmented cerata of F. browni are smooth or slightly wrinkled. The cerata are arranged in groups rather then rows. Around the tip of the cerata there is a white pigmented ring. F. browni lacks pink tint on the tentacles and warts on the rhinophores, features often seen on the similar F. verrucosa. Small individuals may be confused with F. gracilis.


It seems to prefer current exposed locations where the major food source, the hydroid T. indivisa, can be found.


F. browni has been registered across the northeastern Atlantic Ocean, including the North Sea, Norwegian Sea and the English Channel.
