Orange Marks on Pear Tree Leaves

Question

We live in Germany. We have a Pear tree in the garden. Over the last few weeks, we have noticed the leaves have orange areas on them with what looks like either fungus growth or egg sacks on them. The growth has what I can only describe as four peaks, with white bases and black tips. Is there anything we can do or is our Pear tree doomed?
