Phlyctis is a genus of lichenized fungi in the order Gyalectales, and the type genus of the family Phlyctidaceae. Members of the genus are commonly called blemished lichens.[1] [2]
The genus was circumscribed by German lichenologist Julius von Flotow in 1850. The Dictionary of the Fungi (2008) estimated the widespread genus to contain 12 species, but several species have been described and added to the genus since then.
