That is my leaves. There are these white mushroom things coming out from the bottom of the leaves. The rest of the trees leaves are yellowing a little and have these yellow spots forming. there Is no curling on the leaves and they are held normally. I am worried dead and ha e been for a month because i cant disgnose it with whats on the internet, because apparently NOBODY on Earth has seen these before

Can you tell us a bit about your growing conditions, it appears this is an in ground citrus plant. What climate are you in, what type of soil do you have, do you know the soil pH, also how do you fertilize, when and how much, ...

I can't see the mushroom things you speak of. Could you post a better photo?
