Bill, I think you need a Zygostates! I grew one for years, got it that time from Hoosier Orchids, Zygostates apiculata. Your growing conditions would fit! It always flowered in March.
and when the mount fell apart I grew it in a small pot. But that was a mistake, as I lost it the next Summer. They really like to grow mounted and I always water with rain water. Light is similar to Phals.
