Sorus (plural sori) is a cluster of sporangia, which is the structure producing and containing spores. My first post back on September 30 showed licorice ferns unfurling from the first rains at the end of summer. Since then, the sporangia have been developing and you can see the sori on the underside of the leaves in two neat rows. They look so beautiful and delicate. Yet, I get the feeling that they sturdy and hardy too. I have been checking on them fairly regularly to see when they are going to release their spores.
Below you can see a forest of licorice ferns growing on a fallen tree, and there is another photo of the underside of the frond.
