TL;DR I'm trying to identify a pathogen on my agave.
I have an Agave americana in my yard in New Orleans, LA. It has generally grown vigorously, although it sometimes struggles during wet + cloudy spells. For a while there was clearly an infection in the center whorl (meristem? where the leaves emerge from) that produced some brownish liquid and rot, and I thought the plant was a goner. I did a little surgery and tlc on the plant, and it recovered and has continued to grow.
However, since then a few interesting circular scars have emerged. The plant seems to be fine, but I'm interested in identifying what this might be. Not sure if it's a fungus or a virus, but I haven't seemed to find the correct combination of google search to find a convincing picture of the scars.
