Weird one... cant really Id this FUNG!?!

Tobias,

Annual and with pale brown spores 7-8.5 x 5-6.5 µm ? If so, Inonotus dryophilus, also known from living oaks from a few localities north of Stockholm. And the Ekticka doesn't resemble the perennial Phellinus robustus, but looks much more like the annual Hapalopilus ritulans.

Is that on the Stockholm oak?

They are actually from same tree and same spot... Weird looking ones.. I cut a wedge from one and it was sort of greyish inside... no guttation that I could see. Not anamorf Laetiporus, Perenniporia or something?

 

Found a picture of kärnticka - Inonotus dryophilus that resembeles the ones in the pics.

Yes it is.

If it is Ceriomyces aurantiacus, which mostly fruits inside hollows, (also) guttates first and then disintegrates to a powdery mass, you would find lots of cinnamon 7,5-20 x 6-15 µm chlamydospores. And as Perenniporia does't fruit at this height, I. dryophilus still is a candidate : microscope.

Oh the joy of the fungal kingdom!

 

I took a wedge of one of the brackets and left it to dry... The reproductive layer opened up and, hey!

 

 

Daedalea quercina:thumbup:

Tobias,

Which implicates, that not only the identification of the (panic fruiting and partially sterile) bracket fungus was wrong, but also the assessment of the type of wood rot and with it the effects on (the stability of the crown of) the tree , a tree in which only those brown rotters were active, that are part of the second phase of the tree species specific life cycle.

Would you mind to elaborate? I dont know much about Oak mazegill except its a right pretty one... Specifics about this find much appreciated (and in relation to Laetiporus...) Brown rotter? Only heartwood? Necrotrophic?

Daedalea quercina is a perennial tree species specific necrotrophic parasitic, although mostly saprotrophic brown rotter in/on oak decomposing heartwood of the trunk of upright standing trees at greater height (first photo), of fallen trunks (second photo) and of stumps (third photo), that are decayed and hollowed in a way comparable to what is caused by L. sulphureus, which also can be present in other parts of the tree (trunk base, major branches) then D. quercina is.
