It has a ring. I am waiting for them to pop up again to see for certain. I am pretty sure the neighbor’s tree is Western White Pine.

Was there a ring on the stem??

It looks like there might have been in the pic.If there are more look and see.Rogers says only sibricus has it.And Bessette says it only has it sometimes.

The tree in the Pic is a species of Spruce

It may be some kind of ornamental,can you get a pic of the whole tree?The cones in the pic maybe a mutation or caused by diesease.There are as noted different needles in the pics of at least 2 species.A long needle pine nearby could be the source of your Bolete.(as you said in your neighbors yard)But I have seen spruce with simular (Cones?) that are actually the tips of branches caused by blight.Break apart one to see if it has seeds.

If those “cones” are caused by disease…..

They have been diseased all my life. This tree is in my yard, and those “cones” have been fruiting for 20+ years. I’ll keep an eye out for any other sort of cone, thanks for the info.

There is some other sort of pine tree in a neighbor’s yard. I’ll try to figure it out in the morning.

Thanks, fellas!

Looking at your photos of the ground, you’ve also got true pine needles in there, some of which appear to be clusters of five, making it a white pine. That could be your mycorrhizal host, as well. Tree roots spread far!

are of at least two different pines, a three needle and a five needle (the one the Suillus is growing with) I did see some eastern White Pine planted in Seattle when I was there… see if you can get pictures of the five needle pine in that area.

Looks like a spruce (Picea sp.). The bumps on the twigs where the needles attach, radial needle arrangement, plus rather platy bark, convince me. The needles probably feel sharp to the touch, although not all spruce species follow this rule. I don’t think those gray spiny things you’ve photographed are cones, they’re probably malformed twigs and needles due to disease. Look for cones on the ground or hanging up towards the top of the tree. Spruce cones are usually long and skinny and relatively soft in the hand. See the Gymnosperm Database for more details.

of the tree in question. I will update with photos of bark and branches.

No cone

that’s a twig with needles, and it’s not from pine either..

Anyone care to enlighten me to a genus at least for this tree? I can get pics of bark and needles if necessary. I cannot find this cone in any of my field guides and it is driving me batty!

S. americanus

Grows under White pine, East of the Rocky Mountains. This is growing under something else on the west coast. I am having trouble identifying the tree, I am ashamed to admit, but it is not White Pine.

Just curious…

why S. sibiricus and not S. americanus? Afaik those are considered to be two separate look-alike species now (I could never perceive the difference visually I must admit), and the difference is primarily in their habitat choice; the former grows under Pinus sibirica (at least here in Siberia), a five-needle pine. What pine species did it grow under?
