I have cut 6 of those wood posts into planks with the idea of using them for a coffee table as per the other thread. I am thinking that I will need at least two different woods to make the table big enough for the new request so need to know what these woods are. 2 of the bits appear to be the same so there are only 4 different woods to identify.

A) 
B) 
C) 
D) 
I will start with I think B is oak
It's wood mate. Glue it together, throw on some Hammerite = sorted.
If it’s on the soft side the first one looks a bit like Tulipwood.
My guesses-
A - softwood of some type?
B - oak.
D - walnut? Looks nice.
Good quiz!
I basically decided what I thought they were on the previous thread (unsawn) and now appear to be doubling down on my guesses even though they’re probably wrong.
I’m going for:
A) chestnut. Sweet. 60% certain.
B) oak without a doubt. Medullary rays are a giveaway if nothing else. 100% certain.
C) I thought I saw some European/English walnut in the unsawn pile. This looks like the pale sapwood of European walnut. 30% certain.
D) I’m going walnut again, but with some fungal madness going on. 20% certain.
B is oak
I thoguht A was beech with a bit of spalting starting but tulip wood (poplar) could be right.
Funnily enough looks a bit like Brazilian tulip wood nut i think it might be peach and C might be peach too.
Infact Peach can look a bit like A aswell.

where did it come from?
A - This does appear less dense / softer than the others and has a lot of knots line a cheap pine but is definitely not pine. I guess it could be tulip wood as a quick Google of that shows lots of wood with very clear and similar grain patterns.
b - Yes Oak. All agreed
C - I think this was 4th from the left in the original photo below. This was quite splintery when sawn. Somewhere I remember hearing that they didn't make wooden battle ships out of teak because it is a brittle wood and would shower people inside the ship with splinters if hit from the outside with a cannon ball. Could it be teak or is my memory completely shot?
D - I think this was 4th from the right in the original photo below.
3rd from the right hasn't been cut yet as it has a pretty grain pattern and I do want to cut it until I know what I will use it for.

Not sure if this helps
I’m leaning towards this response, it could be the wine:
It’s wood mate
So which woods will work well together and which should I avoid using for a coffee table then?
I've got a sheet of tulip veneer it's similar tbh
B oak
C walnut it can be funky even white half way up a plank.
D looks like far eastern pallet wood could be anything.
Oak for the top of the table
So which woods will work well together and which should I avoid using for a coffee table then?
Aha! Now there’s a really good question. Because what species of wood we have in front of us is not so important as “how good is this wood for xxx”
And internet advise is often wrong. Use your eyes and hands Mr WCA.
I’ll digress with a little story;
I began my journey into amateur woodworking with a desire to build drums. If you go to a shop to buy drums, much like guitars, they are made of maple or very occasionally black walnut because apparently it’s amazeballs. If you google timber species suitable for making drums, apparently you absolutely must use maple. Occasionally black walnut for its peculiar tone. I built a snare drum from expensive American black maple. Then i built the toms and kick from that same species. Turns out these are just trees that grow in North America, and that’s where rock drums come from…
So then I built a snare drum from English ash that was readily available at my local sawmill. I’d gained a little experience building a drum from the “right” material, but I could immediately tell this local timber was hard, had a fine resonance, and worked well on the tools. The end product is beautiful - I prefer my ash snare to the “correct” walnut one.
The moral of the story? It’s this; What do you want to make your table out of?
Edit; with a little caveat. Stack those planed boards carefully, and flat. Have a look at them next week and reject the ones that have turned into bananas. Saw the bananas into shorter pieces for another project.
Thats a really good point, they'll be useless if they dry all warpy.
tickered stack to let air all round them

Teak also contains a higher level of toxins (anti-fungal but affect humans). Working with teak can produce allergic or sensitivity reactions. So I think it was the toxic effect of the splinters, as well as the brittleness.
