A Log of Jellies

We had been walking through Dunrobin Woods for over an hour this morning without seeing anything worthy of a picture when, in the last quarter mile, we spotted two blobs of jelly on a large rotting log. Each was about 30mm in diameter and had....

....no real structure within them. However, they were closely associated with purple structures which may be....

...the purple jelly disc fungus Ascocoryne sarcoides. However, there is nothing on the First Nature website, which is good on fungi, to suggest there is any connection between the two.

Another blob of jelly, much the same as the first two, was on a nearby branch of the same log and, perhaps coincidentally, it also had a purple jelly fungus close by. I have tried on the internet to find a jelly fungus to match the jelly-like one, without success.

Excited by these finds I looked under the log to find yet more fungi. I think there may be no less than four more species here, starting with the one at bottom left which is similar to the first large jellies but is more opaque and has a little more structure to it. Then....

....there's the orange one, which may be Phlebia radiata, the wrinkled crust fungus. The third species is seen in the bottom centre of tha above photo, with a sort of trumpet structure. Th nearest I can find to this is the tripe fungus - what a lovely name - Auricularia mesenterica, but I really am guessing.

Lastly, there's this one, which may be the same species as the previous tripe one, although it is quite a bit larger.

If.... if I'm right with these, there are perhaps six different jelly fungi on the same rotten tree. Fungi spread through their spores which are blown by the wind, so what is there about this particular rotten log which enabled it to collect and nurture so many different fungi?
