nouncephalodium (plural cephalodia)
plural cephalodia
- A small gall-like structure found in some lichens that contain cyanobacterial symbionts.
The Nostocoid type consists of small rounded blue-green cells not over 5p. in diameter and arranged in chains which are often much broken up in the cephalodium, so that the concatenate arrangement is hardly apparent.
