Sorus
Sorus
Sorus (pronounced: /ˈsɔːrəs/; plural: sori) is a term used in mycology and botany to describe a cluster or collection of structures, such as spores or sporangia.
Etymology
The term "sorus" is derived from the Greek word "sōros," which means "heap" or "pile." This is a reference to the clustered nature of the structures that the term describes.
In Mycology
In mycology, a sorus is a cluster of spore-producing structures, or sporangia, in fungi. These structures are often found on the underside of a fungus and are responsible for the reproduction of the organism. The formation and arrangement of sori can be important characteristics for the identification of certain species of fungi.
In Botany
In botany, a sorus refers to a cluster of sporangia on the underside of fern fronds. These structures are typically covered by a protective layer of tissue known as an indusium. The arrangement and shape of sori can be useful characteristics in the identification of different species of ferns.
