Weird Growth on Phal

[Wild Orchid]

Hello, Everyone

My turn to report something really weird looking on the Phal. I just happened to spot it tonight when putting a plant under growth lights..... The bump at the base is shiny, swallen and almost looks like... a tumor. Definitely not like a root.... Basal keiki?? Shall I be concerned? I never seen anything like that before.
It's a rescue Phal that been through Sphag-N-Bag for a few months, and then regrown its roots and leaves all over again and been doing really well after repotting.... So I don't think there's possibility for scale or other bugs to hide in the tissues....

Your expertise and suggestions are much appreciated!
