Pear Tree Problem

[Lymmguineas]

Hi Everyone,
I bought a cheap pear tree from Aldi earlier this year which seemed to have established quite well and looked quite healthy - despite the bark being chewed by rabbits within the first week or so!
This week however I've noticed something dodgy on some of the leaves.
It looks like some sort of fungus.
It's on the underside of the leaves and appears to be a brown lump with what look like roots growing out of it.
I've removed all of the affected leaves (about a dozen) and watching for any more.
Does anybody know what it is and if I need to do anything else other than remove any more leaves that look infected?
I've attached a couple of photos.
All advice welcome.

It’s rust I think,mine has the same I just cut off the sections & throw in the landfill bin,are your leeks alright,check if there’s rust anywhere else it spreads by spores I think.

Thanks Jane.
I've not grown leeks this year, but I know the guy on the next plot has them and that they've got rust.
I'll keep an eye on them.

It's pear rust.
Those growths are the fruiting bodies of the rust fungus, which you only see late in the season.

If only a few leaves are affected, just continue to pick them off, but if a lot are infected, just leave them - you picking the leaves off would do more harm than good.

Indeed, to my understanding pear rust cannot be caught from other infected pear trees, anyway.
Pear rust has a strange two-stage life cycle. It infects pear leaves, which produce those fruiting bodies, then the spores from those infect the stems and branches of juniper trees, which then produce their own spores which infect pear leaves again. So it's infected junipers which will infect your pear.
