These sori are covered by a tan, hairy, kidney-shaped indusium. Sori may be covered by a structure called an indusium. She describes the plant as having a vestigial indusium. The indusium (cup enclosing the stigma) is hairy. Sori are round and covered in a bladder-like indusium. It is continuous around the genu of the corpus callosum with the indusium griseum. The sori are round, with a peltate indusium. The sori are covered in a kidney shaped indusium which is smooth. They are covered by a prominently whitish to brown reniform (kidney-shaped) indusium. The netlike openings of the indusium may be polygonal or round in shape. The sori are usually rounded and are covered in an inflated bladder-like indusium. The species resembles "Phallus indusiatus", but that species has a longer indusium and smaller spores. They produce sori, which lack a true indusium, within the inrolled margins of the pinnae. The leaf margin does not form part of an indusium, as in other Dicksoniaceae. A flap-like indusium arises along one edge of a sorus.
