fungs? on my indoor lemon tree
Thank you for sending your photo to Ask an Expert. I'm having a hard time discerning for sure, but it looks like you could have mealybugs on your lemon tree. Below is a publication about controlling mealybugs on houseplants.
If this does not seem to match up with what you are seeing, please bring in a sample of the branch with the problem to the Yamhill County Extension office and a Master Gardener can help you identify it.
