Orange dust on house plant. Any idea what it is? Have never seen this before. Any idea what this is on my Philodendron Birkin plant? I noticed a mushroom last week and today there is all this orange dust on it. I’ve been researching and can’t identify the issue or how to fix it. There is a new mushroom so maybe it’s a type of fungus? It gets moderate indirect light and I water it 1x a week or every other week. I wait for the soil to dry out before watering.
