I'm just back from the orchid show and am trying to sort through purchases and pictures but thought this more important. Elaine, at first glance, this looks more like Guignardia Leaf Spot than Erwinia or Pythium. The lesions running parallel to the vains is a big clue. You can fight this with Captan or Mancozeb.
