A flap of tissue covering a sorus. False indusium. A folded leaf margin protecting the sorus. True indusium. An epidermal outgrowth protecting the sorus. Inferior indusium. An indusium attached beneath the sorus with the sporangia appearing above it.

An epidermal outgrowth or reflexed and modified leaf margin which covers the sori of many ferns.

an outgrowth from the leaf, evolved to protect the sori

On a fern, the protective covering for the Sorus, the cluster of spore producing Sporangia. Not present in all species.
