I don't think so but am willing to be slapped on the wrist if it develops into a D r.

On the other hand, I cannot at this moment suggest a sp.

I wonder if it could be Diplolepis mayri?
Alot of the images on the web are of an older browner looking gall but I found an image in a book which looks good for it.

Were you inside when you did this?

.

I have never fancied cutting them open myself I would be worried incase I sliced the insects which were inside the gall.

no i was outside and i started screaming and then my dad sprayed me with the hose because he thought they were spiders

These strange looking galls found on a beech leaf 10-11-2010 NPZK, North Holland were made by the Mikiola fagi gall midge.

Sorry to repeat this, but I thought it better to move the ID'd gall (now I know it is a gall) with the other types of galls to keep the info together for gall reference.

goosey · #57 (**permalink**) 02-05-2011, 09:30 AM

These had me confused, but now we are pretty sure they are an oak gall of some sort, although I stll can't find images or names of the galls on sappling stem.
I thought I would add the picture's to this thread to go with all the other gall images, rather than leave it loose on the wild flower forum

. (original thread can be seen here Berry ID please )
Image 1. shows them on bare stem.
Image 2. Some a few weeks later with foliage, so we could pin down the plant.

Here we are yet another type of gall!
An Artichoke gall found on an oak sappling. I took a picture and wandered off then had a little panic as I thought it wasn't gall but a Rhododendron bud so I had to go back and make sure, yep it was firmly attached to the oak. I should have checked my camera, it looks nothing like

This gall I spotted on a peach tree in England - I haven't come up with a name for it yet.

Its a fungal infection Peach Leaf Curl nasty thing

the bain of my life I have lost many trees over the years because of it we use Copper Sulphate to kill it but its a long process

Oh, so not a gall after all, I had better warn my mother in law, it was her tree

. Thanks

I think I have this right, but if not tell me

.
These are Pontania proxima wasp galls on the willow and I have loads of them.
What has interested me though is the fact that on the same plant and leaves are Sawfly larvae - Croesus septentrionalis and they have stripped the leaves as usual leaving just the central vein and the galls

.

chris butterworth · #63 (**permalink**) 18-06-2012, 11:58 AM

The galls are Pontania sp. Goosey but ........... depending on the species of Salix they occur on they could be from a couple of species of that genus.

Chris

p.s. I didn't know - until now - that there was anyone else interested in Galls here.

chris butterworth · #64 (**permalink**) 21-06-2012, 02:40 PM

Which Pontania sp. galls on which Salix sp.? I've just got round to sorting them out and ........

P. proxima only on S. alba, S. fragilis and S. viminalis
P. triandae only on S. triandra ( easy, that one.

)
P. bridgmanii only on 'Sallows' S. caprea, S. cinerea and S. aurita

As with all galls it helps if you know the species of plant they are on as many are very species specific when it comes to the plant galled, but I'll bet you already knew that.

Oh yes, there are some really interesting threads knocking around here

, but some of the best topics and converstions have ended up in the gallery, when a chance remark or photo has started a whole lot of intrigue off!

I think I must have had a reason to have decided on Pontania proxima years ago when I noticed them, but can't remember why but I would have checked it out.

I don't know which willow I have, it started off as a bunch of twigs used as a paasboom (Dutch Easter tradition to decorate willow branches with fake eggs, chicks and rabbits). I had them in a vase of water, they took root and I planted them in the garden. Within 5 years it was over 9 foot tall - much too tall for my garden (4 x 3.5m) so I cut most of it down in February to about 18inches, it has grown again and in full leaf.

Here is another gall found today on wild rose. A new type I haven't seen before or at least in this form, the hip has become distorted large and flattened out.

I've been checking through " British Plant Galls" by Redfern and Shirley ( a cracking set of keys from the Aidgap series by Field Studies Council ) but nothing like this appears in the book. There again it does only cover British galls. I'm wondering if it is a 'misplaced' Smooth Rose Pea Gall. If so, then it could be either Diplolepsis nervosa, D. eglanteriae or D. centifoliae. The only way to determine which it is is by raising the adults.

These are Neuroterus quercusbaccarum, caused by the sexual generation, and are probably completely hiding the remains of the leaf they developed on. The agamic generation causes Common Spangle Gall.

It is a Gall, but a fungal one, caused by Taphrina deformans. Other Taphrina galls you might have seen include 'Witches Broom' T. betulina on Birch and 'Pocket Plums' T. pruni on Blackthorn.

That is excellent, thanks so much, it is good to have a name for these after all this time.

Well done and thanks Chris, I shall add Taphrina deformans to the title and key words so it shows up in searches if anyone is looking.

New galls I've found this week include ones by the mites Aceria cepholoneus on Sycamore + Rhabdophaga marginemtorquatus on Salix fragilis, Gall Wasps Cynips quercusfolii on Sessile Oak + Neuroterus quercusbaccarum on Pedunculate Oak ( the latter was completely covered in a mould fungus ) and the Sawflies Pontania bridgemanii on Salix caprea and lots of P. proxima on S. fragilis. The P. proxima on a line of Willows near to my house were infected with a smut fungus which will probably kill off the developing larvae inside the galls but, the trees c.3km away were completely clear. I just need to figure out how to post photos on WAtW

and then all will be well (ish)

. ( Black spent far more time than could be humanly expected explaining it to me on Saturday but ........... daft old bugger that I am I still can't get it right

Here are a couple of links with pointers into uploading to the gallery and another for adding images to forum posts.

The appearance of dozens of these galls on my Azalea over the last few weeks reminded me I had images in the gallery of some from 2008 when I put them up for ID not knowing they were galls. Now I realise, these galls caused by the Exobasidium vaccinii fungi rather than wasps don't aren't mentioned on this thread.

(Images from 2008)
