Virused plant?

[camille1585]

Yes there are many viruses, but the tests generally pick up CymMV (CMV is something different: cucumber mosaic virus) and ORSV, because those are generally the 2 most prevalent viruses.
To make things tougher, not all symptomatic plants are viruses and not all infects plants show symptoms. Most mass propagated Phals are believed to be infected for instance. So if virus worries you, test your entire collection. And I bet that you will be very surprised by the results. For most people virus isn't too much of an issue, unless they have a collection of very expensive orchids, or are collecting divisions of old heirloom Catts for instance.

For your fungus question, my knowledge in in 'normal' plants (they don't teach orchids in college!) and streak creating fungi are very common, especially among the monocots (think grasses). Orchids are monocots, so it's fair enough to assume that they could get similar things.

As for Glen's suggestion, I hadn't thought of it, but it's definitely something to consider. Are you sure that the plant doesn't have a mite infestation? Symptoms are similar to that.

As for Onc leaves being ugly, that's sometimes their nature. They can be prone to spotting and such if you mist them, or if they are in high humidity with low air movement.
