No specimen available

Can anybody identify this mushroom with its spruce seedling? I thought it was a maitake but have been told they don’t grow that far west.

Was this found in sandy soil or sand dune area? How wide was it? The spruce cone in the photo seems to indicate a width of about 12-15 inches. Was it? Did it have a fragrant, agreeable aroma? If yes to all the above, maybe Hydnellum suaveolens as Amanita virosa suggests. I usually associate H. suaveolens with red drops on the pileus, but that is not the case in Smith, Smith & Weber. Of course, S, S & W was published a few years ago too.

Don’t know about Coos Bay,

but Grifola frondosa has been found in the Hoh rainforest of Washington. It has also been cultivated for so long now in Oregon I suppose almost anything is possible. That said, this doesn’t look like Grifola frondosa to me. There are not enough fronds and smaller lobes. It looks to me more like an older Laetiporus coniferoides; or a bleached out Phaeolus schweinitzii maybe.

Both those species should be growing from wood. We have nothing in this observation indicating what it was growing on; just with a seedling spruce. The only spruce I can think of that would be growing native in Coos Bay is Sitka spruce. And it’s near the southern border for its range there, I think.

Really need to see the spore-bearing surface on this one for a better guess. But like most others, I’m near certain this is not Grifola frondosa.

bottom lobe looks to large. Wild Guess would be Hydnellum?
