Soredia and Isidia are two different types of reproductive structures produced by lichens. Both soredia and isidia play important roles in the reproduction and dispersal of lichens. However, they differ in their structure and function. In this post we discuss the Similarities and Difference between Soredia and Isidia with a […]
