I discovered this thing which looks like a fungus on my phal and I put the whole plant to soak in bucket of fungicide, I also took off all of the things and hung the plant away from other plants, I have the plant hung where it gets sun and rain, I had it hanging on a wire basket where a cattleya is planted in coconut shells with stones, coals and some fiber, I am wondering if it had picked up the fungus from water dripping on it from that plant, it is the only one that has that on it,
