This tree could be a species of Cladrastis? Most commonly grown one in this country is Cladrastis kentuckea, but there is also Cladrastis sinensis (American/Chinese Yellow Wood) but then of course the wood would be markedly yellow in colour... Otherwise this one has stumped me and I would have suggested the usual suspects as previous posts.

Previous mention of Mulberry is correct, its likely to be a weeping/compact form of Morus nigra. I can see differing leaf shapes.

Nope that one is not Sorbus sargentiana as the fruit clusters and leaf is different. Looks like the commonly sold clone of sorbus commixta known as 'Olympic Flame' or perhaps 'Dodong', either way a lovely tree with great autumn colour.

The work on Sorbus by Hugh Mccallister is an excellent book on Rowans and describes s. sargentiana very well, it also shows you how many lovely small species there are. It says that the leaves in this sp. are larger than any other except perhaps Sorbus harrowiana (lovely small shrubby tree). A good read if you are into Rowans.

Second image in Dalton trees also shows, the basal leaflets, which is characteristic in s. sargentiana and other related Rowans. If original poster can take shot of these then it could be more diagnostic.

Yep, foliage seems to match, although the buds on this one appear green I'm still positive the original picture is of s. sargentiana, there are a few related species eg. s wilsoniana and s. insignis, but it doesnt fit. This species is typically grafted onto s. aucuparia rootstock.

Which further strenghthens the case for s. sargentiana. I know it's shocking to see a rowan species that has nice bold foliage. I think its the lack of close up of buds and no fruit corymbs which would give it away. The general 'stout' appearance of the twigs and tree absolutely give it away as sorbus sargentiana. What context is this tree in? arboretum? park?

Still convinced it's a S. sargentiana. The description matches what I see in Flora of China - Sorbus sargentiana in Flora of China @ efloras.org. The leaflets are starting to turn the classic yellow/red autumn colour of s. sargentiana, starting from the edge and that reddish sticky bud is a give away. Leaf veins match, and it has large leaves for a Sorbus. Stout twigs/branchina and a small to medium size tree. This particular individual obviously didn't fruit well this year, because if there was fruit cluster that would be a key diagnostic feature also: https://www.google.co.uk/search?q=sorbus+sargentiana&espv=2&biw=1517&bih=714&source=lnms&tbm=isch&sa=X&ved=0CAYQ_AUoAWoVChMIjceUiszlyAIVS9gaCh2Pgw0R&dpr=0.9#imgrc=_

This tree looks to be Sorgus sargentiana, large pinnate leaves and what look like sticky reddish terminal buds. Lovely species, one of the nicest in the genus.

I grow seeds of both native and non native tree species, often 'nabbing' seed from nice specimens. Recently I set out on a project to grow acorns from veteran oak trees from in and around Great Malvern (Malvern Chase). Needless to say they came up like mustard and cress and have spent much of the summer potting them on -it was a proper mast year last autumn. I find that many of the seeds just benefit from an autumn sowing, that period of stratification and often they germinate the following spring. The trick is to plant into seed trays or deep pots to minimise the transplant, I'd also recommend protecting them in a cold frame or something 'squirrel proof'. Maples - they require the outer casing removed/ or chipped slightly to allow the ingress of water. I have some experience of growing wild service/true service tree also, they require cleaning carefully and then a period of cold treatment. On a side note I also plan on taking cuttings from nearby Populus nigra subsp. betulifolia and growing them on to plant in floodmeadow. I know of a great population of these charismatic trees and intend on exploiting them.

Interesting David, nice to build up a picture of where this fungus gnat is present. The larvae can pupate in the silk cocoons on the bark and the fungus apparently. A quick search for Sciophila ochracea (a syn) comes up with some images of the gnat. My email correspondance with various people have stated that the only way to tell is to rear them to mature gnats for an ID. https://data.nbn.org.uk/Taxa/NBNSYS0100018006/Grid_Map - distribution.

Those webs look like something have seen here in the UK before, a fungus gnat Sciophila pomonae, which produces curious webbing with holes on Phellinus pomaceus. This fungus clearly has a few associates with it! ref my post: http://arbtalk.co.uk/forum/ecology/49772-hamadryad-trees-ecology-fungi-22.html#post940187

Becuase I'm a complete sucker for the 'beauty' of trees it'll have to be.. In no particular order for a smallish garden. 1. Davidia involucrata 2. Liriodendro chinense (daintier and smaller cousin of tulipifera) 3 Dracanea draco (not growable outside in UK winters, but mature trees are most distinctive)

The subsp is apparently hardier - but Scotland is pushing it, maybe somewhere fairly sheltered or with wall protection sheltered from buffeting winds.

Yep looks about right. Is probably the Catalan ironwood - Lyonothamnus floribundus ssp aspleniifolius. I was puzzled over the identity of a fairly large specimen of this in a front garden near Hampton, London Borough of Richmond... Nice to put a name to it.
