I.D on our village oak tree please

[SteveA]

This old oak tree in our village has this huge white streak - what is it?

Cheers, Steve

It may be a crustose form of Lichen, but not overly confident of that.

 

Your close up looks like it shows small specks which may be the spore structures, I've read that in some species you don't always get the cup like spore bearing structure (apothecia) like you see in a lot of other species.

 

A search offers up a number of similar looking white crustating lichens like Pertusaria amara.

 

 

Perhaps get in touch with Robin Crump who's the Pembrokeshire contact of the British lichen society

Lovely thankyou. I guess it could me some kind of

lichen. I'll drop an email to Robin....

Let us know how you get on

I'd be interested in the outcome of this too. I've seen similar markings before, in North Wales I think...

Yes, will do.

i always thought that when i'd seen a tree like that in the park or something that some **** had just painted it. i always thought lichen was small patches and never realised it could smother the tree like that.

Yes I thought the very same.

Not 100% sure it's lichen yet but Pertusaria amara (images of British lichens) could be a good shout.... although could also be Pertusaria hemisphaerica (images of British lichens)

 

May have to give the tree a lick to see if it tastes bitter, and hopefully not be seen!
