Hi everyone,

I've had this finger lime tree for a number of years now, and I have never noticed this sort of growth (?) or bug (?) or (??) before.

It doesn't look normal for sure. Tried to scratch it off with a branch, but it wouldn't come off. I'm sure if I scraped it, it would.

I'm leaning towards scraping it off. Is this an indication of worse things to come? I've no idea what this is.

I live in Melbourne, Australia.

Thank you! 😫

Edit: To clarify, it is the red thing with the white dots around it.
