Not seen this before on apples

This is off my bramley apple.
Looks more like peach leaf curl to me, never seen it on an apple before.
Any thoughts?

 

Get that sort of thing with the leaves on my redcurrant bushes, something to do with a type of aphid, doesn't harm the bushes.

 

Thanks @Logan , I've got a feeling this is fungal though.

 

Your welcome, anytime

 

Logan's right, @pete Apple tree problems: frequently asked questions / RHS Gardening Have a look at the leaf problems bit. There's an aphid that causes this.....it's a new one on me too Aren't we the lucky ones, growing's never boring with so many pests and diseases to choose from

 

Well I'll take your word for it.
I can't find it in that link.

 

@pete The closest I could find was this Rosy leaf curling aphid (Dysaphis devecta (Walker)) - Apple Best Practice Guide
Certainly the red coloured distortion is very distinctive and my first thought was fungal, but couldn't find anything.

 

If you cannot find any insects then itsTaphrina, a fungal infection, more commonly known as leaf curl, more prevelent in stone fruits, but there are other strains that infect other fruiting and non fruiting trees, including Alder and apple, for example Taphrina deformans is the strain in peach, Almond, Nectarine, whilst the cherry tree version is Taphrina cerasi.
Taphrina is a pathogen that effects trees not just of the Prunus family, with the loss of chlorophyll the leaves blister and turn red, the fungal infection is difficult to control in our current climate, very wet followed by very warm periods, you couldvtry Bordeaux mixture.

 

Well must admit I thought it was fungal, but looking at the link @NigelJ has put up it does look very much like it.
Sorry @Logan I dismissed you suggestion.

@Cuttings ,that is the reason I assumed it was fungal as the thickening of the leaf and the white and red really is a good mimic of peach leaf curl which I've seen every year on my peaches, though it had jumped on to the apples.

 

Yeah, I think it looks pretty

 

I'll put some in the post for you then.
