I am happy to help.

Can I use this?

The first image is a nice representation of Gyroporus. Is it OK if I borrow it for use in a publication? Of course I will give you the appropriate credit for the photo.

I still beleive it’s castaneus. What you see as bruising when the pores are smeared, is probably a pale ochraceous colour from the spores. It won’t appear if you just cut through the pore layer.
These are still young, the stem becomes spongy and hollow with age.
But you should of course be open for better suggestions.

Some of the characteristics of this do not match G. castaneus

For instance, it bruises brown and it has a solid stipe (one of the specimens had a small whole inside the stipe more or less towards the middle of it).
