Genus of liverworts
 ;templatestyles src="Template:Taxobox/core/styles.css" / ;
Blasia pusilla is the only species in the liverwort genus Blasia. This species establishes a symbiosis with nitrogen-fixing cyanobacteria of the genus "Nostoc", which are housed in special cavities, called auricles, occurring on the ventral (underside) surface of the thallus.
"Blasia" is distinguished from "Cavicularia" by the presence of a collar around the base of the sporophyte capsule, and a scattered arrangement of sperm-producing antheridia. Rhizoids and gemmae of "Blasia" may be parasitized by the mushroom "Blasiphalia".
The genus name of "Blasia" is in honour of Blasius Biagi (ca. 1670 - 1735), an Italian clergyman from village of Vallombrosa.
