What is this Disease on Pears from my Fruit Tree?

I noticed nearly 1/4 of my pears on my pear tree
have rusty colored spikes or appendages adjectives over them.
I tried to rub some off and my fingers get orange powder
on them.
Some of the pears are totally covered near this.
The leaves are healthy looking and most of the pears
look forceful.
I hope you can view the pics I hold included.
