host is probably P. cerasifera based on green, non-spiny twigs, long fruit stalks and oval fruit shape. Redfern et al record T. pruni from P. spinosa and P. domestica. P. domestica is supposed to be a hybrid between P. spinosa and P. cerasifera, so P. cerasifera as a host would not be so surprising.

Yes of course it's not sloes, I didn't look at the picture properly. That tree is in a line of blackthorn bushes which made me jump to the wrong conclusion - thanks!
