I think I have some more with it
And on the phal I've noticed it on it looks more like the Cercospora pictures
The phal was right next to the Epi and the other two plants I'm suspect of were also on the same shelf.
I don't really have space to quaranteen with everything inside for the winter, and I am also struggling to keep up with my healthy plants just now so don't have the time or energy to try and save them. None of the affected ones have flowered in years anyway, all but one has never rebloomed for me, so I think they may be on the way out
