A terrible year for pear scab, mostly affecting foliage. The usual suspects all succumbed, but to a worse degree, and others varieties suffered for the first time. Worst affected are Santa Claus and Devoe, but Fondante d'Automne and Beurré Gris d'Hiver Nouveau have also showing a lot of yellow/blackened foliage. I think the explanation lies in the very warm spring, which encouraged a lot of soft growth which has succumbed during the colder, more humid months of true summer. Only the fruits of Santa Claus are affected, and only in a particularly dank corner.
