Mdntnmtgmy,
I've had my share of virused plants...and the only way to be sure is to test it.
Knowing the parents of your plant is also helpful. Your pretty Phal probably has a complicated past.

I bought this plant in flower with the pink blooms...2 weeks later the pale yellow ones appeared . The grower had told me that they were 'Highly Variable' so I didn't think too much about it .. the next bloom cycle was really bizarre and I tested it and it tested positive.
Usually the virus shows up as a 'color break' on the flower.

These both tested positive.
sometimes the plant is virused but doesn't show on the flowers.
Sometimes we spray chemicals at the wrong time of the day..or on the bud at an unfortunate time in its development and similar disfigurations can occur.
The tests can be purchased from Agdia.com and cost about $10. each..so it's not worth testing most plants.
If this were my plant, I would segregate it from the rest of my collection and use good hygiene while and after handling it to keep it from spreading to your other plants. Fingers crossed that it blooms normally next year.
If you just got the plant, you might be able to get your money back or at least an exchange.
