I got a Bulbophyllum Ray Gabaldon (Grandiflorum x Bulb. Lobbii) from EOom last October. It was looking really healthy, with vibrant, shiny leaves. I was concerned about bush snails, and this plant was climbing out of its pot, so I repotted it into a shallow basket with tree fern and diatomite. It seemed to have adjusted well. On 18 December I noticed it dropped a yellow leaf since the prior weekÂs watering, and a small new growth near the old end turned black and dried up, as well as the most back bulb. The back bulb is spotted with what looks like fungus--black dots which do not move. It also has what looks like a bite mark--about 1/4 inch across. I sprayed with fungicide a few times and kept an eye on it. Today it dropped another yellow leaf, and over the past 10 days the pbs at both ends are turning brownish and soft. I can see whatever it is, is attacking from the ends. The rest of the leaves and pbs look very good still. I cut off both pbs. Looking at one rotten area under a magnifying glass, I could see what looks like tiny (1/8-inch) translucent worms (three). I can see their gut running along their lengths. I have never seen a bush snail, but assume this is not the beast. Nematodes, maybe??? Does anyone have experience with this kind of pest?
