I had a bout with black rot last year that wiped out most of my catts. Today I noticed a strange discoloration on my Encyclia cordigera and I feared the worst. I have segregated the encyclia from the rest of my orchids. I usually leave a fan running and am careful not to get the new growth wet. I have attached an image of the supposed rot. It's more brown than black, and doesn't feel soft to the touch. Should I be worried? Thanks!
