Soredia are common reproductive structures of lichens.cite book |title=Biology of Plants |first=Susan E |last=Eichorn |coauthors=Evert, Ray F; Raven, Peter H |publisher=W.H. Freeman and Company |location=New York |year=2005 |pages=p. 289] Lichens reproduce asexually by employing simple fragmentation and production of soredia and insidia.cite book |title=General Botany 111: Laboratory Manual |first=Rebecca |last=Cook |coauthors=McFarland, Kenneth |publisher=University of Tennessee |location=Knoxville |year=1995 |pages=p. 104] Soredia are powdery propagules composed of fungal hyphae wrapped around cyanobacteria or green algae. Fungal hyphae make up the basic body structure of lichen. The soredia are released through openings in the upper cortex of the lichen structure. After their release, the soredia disperse to establish the lichen in a new location.
