Sorus

The underside of a fertile frond of Dicksonia antarctica. Each circular brown structure is an individual sorus.

A sorus (pl. sori) is a cluster of sporangia (structures producing and containing spores) in ferns and fungi. This New Latin word is from Ancient Greek σωρός (sōrós ‘stack, pile, heap’).

In fungi and lichens, the sorus is surrounded by an external layer. In some red algae it may take the form of a depression into the thallus.
