What is "athelia"

n. The congenital absence of one or both nipples.

Athelia is the congenital absence of one or both nipples. It is a rare condition. It sometimes occurs on one side in children with the Poland sequence and on both sides in certain types of ectodermal dysplasia.

Athelia may refer to:

• Athelia (disease), a congenital condition in humans where one or both nipples are absent
• Athelia (fungus), a genus of basidiomycete fungi in the family Atheliales

Athelia is a genus of corticioid fungi in the family Atheliaceae. Some species are facultative parasites of plants (including crops) and of lichens. The widespread genus contains 28 species. However, Athelia rolfsii was found to belong in the Amylocorticiales in a molecular phylogenetics study, but has yet not been renamed.
