I have some pest on 2 of my pear trees, insect or fungus?, I have never
seen this before.
Anyone would like to take a look at the pictures I took today?

Currently here in Quebec, most pears are approaching full bloom.

If you know this pest, I would like to know...
-what it is
-is it serious or just cosmetic
-is there any action I should take

Thanks,
Claude
