that I can hardly imagine that this is the same as our european resinosum or benzoinum. I have seen both of them quite often and never came across one which is so orange, so uniformely coloured and without any zonaton in this age. The fruitbodies are already daedaloid in shape, so they must be not very young!

very young specimens

These were young and still very soft and juicy. I don’t recall seeing blue in any of my observation of resinous poly pores.

How do we know

that it’s not the european species – have they been compared and found intersterile? Or has there been any tests of their DNA? I haven’t managed to reach any info about that.

It would complicate things if the american resinosum (that can grow on both conifers and hardwoods) is interfertile with both the european species (resinosum and benzoinum), wouldn’t it?

And btw, these are young specimen – and with a bluish zone too..

not the european species!

Ischnoderma should have a definite blueish zonation, which is only hardly visible in very young specimens, but in fungi of that age should be very clear to see.
