Yellow Staining Bracket

[Ditiola]

Please can someone help with the ID of this bracket.

Bracket fungus on stacked Pine logs

Brackets
20-40mm x 10-15 mm x 1.7mm thick, Upper surface white compact tomentum with some greenish algae and faint zonation

Context
Fruit bodies distinctly three layered, between the poor layer and the compacted tomentose surface is a gelatinous middle layer

Pores
128 microns diameter round to slightly elongated 4-5 per mm, When collected the pores were white staining bright yellow on handling and then the yellow areas drying orange. On un-bruised fruit bodies the pores turning salmon-orange by the following day. Slightly gelatinous but can be squashed when fresh.

Spores
No spores found

Seem like young distorted Chicken of the Woods to me.

If it's COTW then it's the strangest one I've ever seen. The smell would give it away if that's what it is.

Then again I can't find anything else it is likely to be...Fomitopsis pinicola? Wrong shape.

Looks similar to COTW that I have seen - on both sides.

Anoter faint possibility this could be is a rare bracket called Perennipora fraxinia, but I do not believe this has been found on Pine before.

I have been back to the site today and have found some more on the other side of the log pile. This specimen is mostly resupinate in habit. The log pile is in the middle of a pine copse and therefore I am assuming they are pine logs!

Um .... err ....... yes, forget all about the rubbish I said before then.

This is not fully resupinate as you point out, so would be classed as 'pilate'.

Making myself a coffee now and catching up on the papers so will try to get back on this, which basically means I haven't a clue now.

Well, I've just been through the whole of FoS Vol 2, and see no matches, and the fact that Chris and MwnN haven't come in yet seems to suggest this one h'aint gonna be easy.

I'll keep looking though.

Thanks for trying.
I have found some photos of Gloeoporus dichrous and it looks very similar to my material and has gelatonous pore layer. There is also an article in 'The Mycologist' Vol 5: p45. re this fungus. It is British but quite rare and usually on hardwoods. In Nordic Macromycetes Vol 3. p157, there is a Gloeoporus that grows on Pine, (G.gelatinosotubulosus) but I do not think it has been recorded in Britain, and I can not find anymore information on it. I will keep searching my material for some spores, and try to establish a positive ID for the log it was growing on.
