The spore cases of ferns are typically found on the undersides of the fronds, in structures called sori. These sori contain the spore-producing structures known as sporangia.
Ferns reproduce using sori and prothallus.
The spore containing sori of a fern are usually found on the underside of their leaves. In water ferns the spores are produced inside the sporocarps. (Novanet/Gradpoint, On the underside of a fern frond.)

In ferns, a sorus is a cluster of sporangia on the edge or underside of a fertile frond.
The word "sori" is the plural form of "sorus." According to Wikipedia, the free encyclopedia, "In ferns, a sorus (pl. sori) is a cluster of sporangia on the edge or underside of a fertile frond. In many species, they are protected by an umbrella-like cover called the indusium."Source: http://en.wikipedia.org/wiki/Sori
Ferns that have groups of sporangia called sori. Sori are clusters of sporangia found on the undersides of fern fronds where spores are produced. These structures help facilitate the dispersal of spores for reproduction in ferns.
The plant that reproduces using sori and a prothallus is a fern. Sori are clusters of sporangia where spores are produced, while prothallus is the gametophyte stage in the fern life cycle where fertilization occurs. Ferns have a unique reproductive cycle that involves both sexual and asexual reproduction.

The structure you are referring to is likely a sori. Sori are clusters of sporangia that produce and release spores in ferns. They are commonly found on the underside of fern leaves.
In most ferns, spore cases, or sporangia, form on the underside of the leaves, specifically on structures called sori. These sori are often clustered and can vary in appearance, typically appearing as small dots or lines. The spores produced within the sporangia are crucial for the fern's reproductive cycle, allowing for the continuation of the species.
The haploid spores found in clusters called sori are reproductive structures on the underside of fern fronds. These spores are released to disperse and ultimately germinate into new gametophytes, leading to the development of new fern plants.
