In some species, they are protected during development by a scale or film of tissue called the
indusium, which forms an umbrella-like
Kaynak: SorusThe fruit body of the fungus is characterised by a conical to bell-shaped cap on a stalk and a delicate lacy "skirt", or
indusium , that
Kaynak: Phallus indusiatusThe leaves are almost always compound and have linear sori that are typically on the margins of the leaves and lack a true
indusium ,
Kaynak: PteridaceaeThe sporangia are typically covered with a scale called the
indusium , which can cover the whole sorus , forming a ring or cup around the
Kaynak: Leptosporangiate fernMembers of the family all have intramarginal, linear sori with a flap-like
indusium arising along one edge. Most pteridologist s today
Kaynak: AspleniaceaeThe sori are round, with a peltate
indusium . The stipe s have prominent scales. Hybridisation is a well-known phenomenon within this

indusium formed from the reflexed leaf margin.
Kaynak: AdiantaceaeThe edges of the segments may curl back to cover the sporangia, forming a false
indusium . The sterile leaves have thinner, wider segments

indusium formed from the reflexed margin of the leaf.

Kaynak: Cystopteris protrusaThe segments are lined with sori over which the edges of the leaf are folded to form a false
indusium. References : C.Michael Hogan, ed.

indusiumKaynak: Cyclosorus interruptusThe leaf segments bear sori containing sporangia, with the edges of the leaves rolled under to create a false
indusium over the sori.
