Found growing on the trunk of rotten cherry tree which was felled because it was in a dangerous state.
Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
Seeing just a bit further into the fruit-body would have made sure but I think there is enough to show that there is no sterile layer between the two years of tube growth(other than just at the edge)
I was just about to conclude that there WAS a sterile layer and hence that this was G applanatum, when I saw your comment. The sterile layer at the edge doesn't count, I see. Always something to learn, isn't there!
On the specimens I have bothered to cut in half(I normally just take a leaf from underneath covered in the spores) the sterile layer has always been a standard thickness right across the fruitbody. On this one the layer "seems" to stop but we cannot be sure thus my comment.
