Fern frond with sori

Spores are encased in structures called sporangia, which sometimes clump together to form a sorus (plural sori). the spores are clustered on sori on the lower surface of the leaf blade Sporangium type the sporangia are opaque without an annulus and usually without a stalk (leptosporangiate) Fronds usually have clusters of sporangia called sori that stand out from the green leaf as yellow, orange, brown, or dark dots. Sori are arranged differently on the leaf according to the genus of SPORANGIA cluster together in groups called SORI; SORI are sometimes covered by a flap called the INDUSIUM. The shape, location and pattern of SORI on the underside of fern frond leaflets can be an important identifying characteristic.
