Soredium

Soredia on Evernia prunastri

Soredia are common reproductive structures of lichens.[1] Lichens reproduce asexually by employing simple fragmentation and production of soredia and isidia.[2] Soredia are powdery propagules composed of fungal hyphae wrapped around cyanobacteria or green algae.[1] Fungal hyphae make up the basic body structure of lichen.[2] The soredia are released through openings in the upper cortex of the lichen structure.[1] After their release, the soredia disperse to establish the lichen in a new location.[2]
