What Is Meaning Of Aecium?

The meaning of the term aecium is that it is a specialized reproductive structure found in some rusts and smuts which produces aeciospores. Generally, the plural form of aecium is aecidium, in which the spores are always formed in chains and are enclosed in a cup-shaped peridium.

In some of the literature, aecium is also referred to as cluster cups. All the species in the genus Phragmidium have a caeoma which is a disperse aecium with the unavailability of a peridium. In other words, you can also explain the meaning of aecium as a globular or cup-shaped structure in some rust fungi in which aeciospores are produced.

The word aecium is derived from New Latin, from Ancient Greek “aikia”, which means injury, insult. But, as per Merriam-Webster’s information, it says that aecium is a back-formation from aecidium and is not related to the Greek “aikia”. However, latterly, the term aecium was introduced as a substitute for aecidium by the Purdue University plant pathologist J.C.Arthur, in an effort to reform terminology for rust fungi.

In other words, you can also define the meaning of the word aecium as the fruiting body of a rust fungus in which the first binucleate spores are usually produced. The term aecium is also sometimes spelled as aecia.
