No, Bjorn got colletotrichium, he needs to use azoxystrobin or a similar systemic fungicide. That's the same fungus doing the spots on the paph malipoense in his other post.
Paph tigrinum is a complicated species. I grow it very wet, and the Chinese did grow hundreds of clumps before in pure sphagnum moss, soaking wet. They had clumps of some dozen growths this way, easily, and no rot.
Sometimes we want to grow a plant on the dry side, because it prevents diseases, but in the perfect environment, they can be grown wet. The question is what is the perfect environment for tigrinum...
As for Bjorn colletotrichium, it makes holes in the leaves, circles or half circles, and when it spreads, it makes stripes... The holes in the new leaves of the malipoense are the same disease. It tends to stop when the weather is drier, and resumes when it is cold. It is contagious too.
