I was out on survey the other day and I came across three yews with what I thought was this black stuff that you are discussing. here are the pictures. On both the living trees the black stuff was spongy and afrter a hasty inspection I concluded that it was in reality a large build-up of dried exudate, in one case from within an included fork and in the othe case from an inexplicable wound or a very well developed canker. The substance is crumbly and smells a little like the exudate from P. syringae only not as strong and perhaps a little ammonic. Study the pictures if you like. I had no facility with me to take a specimen home but I can go back and get some if anyone's interested. The third yew had a thin fungal body at the base and was completely dead from 2m to the top at 7m, despite fairly vigorous growth at the bottom.

My first thought is Cornelian Cherry, which I think is Cornus mas

I'd like to see that, thanks. Your comments about pruning are noted, I will decide in early March what to do, the frosty weather is causing a few leaves to fall off and I will hold off for a while.

I bet those FC folk are worried about the dreaded P word. One look at those black lesions and it immediately comes to mind then is dismissed in favour of a less alarming diagnosis.

Well, Eucryphia x nymanensis 'Nymansay' it is. They can be dreadfully multistemmed, all over the place really. I saw a particulary ugly one at Benmore Botanics last year. However, there is one near my mum's house at Helensburgh that is a spectacular tree of at least 15 metres, I mean to go back and speak to the owner to see if they or previous owner trained it that way. My specimen is only a few feet tall and I have to make some difficult training decisions soon because it is getting multi stemmed which is fine if I want a shrub but not if I want a tree.

Found a picture of the bark
-
It certainly is evergreen.

Result! I might never see another Morus alba 'venosa' but if I do I'll remember it. The eucalyptus is coccinifera. Here's the final one I have from Arduaine. I have one in my garden too, I liked it so much.
-
Nope.
-
Another caveat, these are the juvenile leaves! I am sure they are sufficiently different from other Eucalyptus that you should be able to nail them.
-
No that would have been too easy. This one is a good deal rarer, we have the Gulf Stream to thank for it surviving in the west of Scotland.

I found my american ident book and there are some odd cottonwoods in it that look promising.
-
One to ponder overnight
-
Bang on! An absolutely gorgeous tree.
-
Are the leaves unfurliung in those pictures? They certainly look like they are heading for Poplar. All my ID books are in my survey box in the car and it's too cold outside to go and get them. The vein form should be definitive.
-
It is not Beech.

I can't keep up... Sorry RobArb, we don't have the same tree at all. Yours is altogether wierd looking.
-
Determined to get a cut leaved alder, aren't you? NO that's not it. And the offer to eat my hat is withdrawn since there is only one common variety of T. dolabrata which you could guess without knowing anything about it.
-
T. dolabrata it is! Variety? Shall I pop out for some ketchup?i
-
Let's see if anyone else gets it, then you can see a fully provenanced label and your misery will be over. Not even willing to hazard a guess at Genus meantime?
-
Bark and foliage this time, if you get the variety I may have to eat my climbing helmet.
-
Oops, your correct Poplar guess came in while I was composing my last posting. Well done.
-
A tricky single leaf ident... from Arduaine again.
-
It may well have been beside a pond in the botanical garden. I think I will have to tell you what it is. I thought it was guessable but I would do as I knew the answer and saw (and heard) the whole tree.
