The reproductive fronds with sori often look brown and dead compared to the lush green vegetative fronds. This high level of variation between the fronds is known as dimorphism and is common to a number of genera of ferns. What you see under a typical frond are the sori (singular sorus), also called or spore cases, that contain the spores. They usually look like small bumps or lines, usually placed in a symmetrical pattern, and are often green at first, becoming brown or golden at maturity. Inside the sori are clusters of sporangia (spore-producing cells). In ferns, the sori form a yellowish or brownish mass on the edge or underside of a fertile frond.
