Pholiota squarrosa on Swedish servicetree (Sorbus intermedia)

 

not honey?

brown lines in centre likely gano, meripilus black broad staining (reaction) gano brown, kretz multiple fine black demarcations

 

i thought merip was the two rings in the centre? the black staining is from that metal i 'discovered'

 

there was no gano on this tree, could it just be that its not fruited?

yes the gano could have been in there without fruiting, you know that anyway!

 

Fruiting is just sex:thumbup1:

Natural history museum says-

 

"Section through the base of a trunk of a larch Larix Europa x L. japonica, showing the darker heartwood in the centre" see image

 

 

Does this look like heartwood formation or something else entirely?

Looks a bit suspect. I thought heartwood was meant to be fixed to rings, not looking like decay breaking through them?

[sloth]

Hmm, something else entirely methinks. Heart wood or ripewood wood be far more uniform and following the growth rings, as they age...

Drop them an email maybe?

indeed!

meripilus and something else on beech, not sure what is causing the black demarcation lines, my first thought could be kretzschmaria deusta? this section of wood was part way up the stem, cant remember exactly!

 

Kd is not always confined to the butt, so you may be right. The black lines are called "spalting" by woodturners, who lay maple logs on the ground for a season, hoping for such coloration.

well thats just daft! only certain fungi cause the spalting, it is the reaction of two myceliums meeting and having fairly equal chemical weapons and hence a stand off is met and a barrier formed. it is also used to seal a fungis mycelium in to a unit of wood against drying and or extremes.
