Bath ernghr the wool came out a silver green, then I did anther bath with ammonia and the wool came out a bronze green, pictures can be seen on my blog journal www.shepthrillsyarn.blogspot.com

I don’t know if you have leucomelaena here. Not unlikely if it grows with spruce, but it’s a European name and this could be another.

There’s a long discussion about the species and names here:

Boletopsis leucomelas can be made, because of the bluish-black to black cap, this certainly is Boletopsis at the very least. Arora has some problems with the genus, as he states "The color of the fruiting body (especially the cap) is extremely variable, leading to the naming of several different “species”, including…" Warty-angular spores seems to be the critical feature to look for microscopically.

Boletopisis subsquamosa group is what I have found in sand dunes along the Oregon coast. I would not be surprised if this was the same. I suspect that specimens forming under a sand cap have lighter colors, while specimens with more exposure to light are probably darker (for example Agaricus bisporus vs. “Button” mushroom vs. portobello). Moss would allow some light in. In both moss and sand, the substrate acts as a casing compound.
