Observation 53612: Boletus L.
When: 2010-09-23
No herbarium specimen

Notes: These are all the same mushroom. There was a huge number of them growing the grass outside my house. They were in various stages of cracking on the cap, so don’t let that fool you. It looked as though (from the lower mushroom) that the spore print was brown, although I didn’t take one. The spores were pale yellow and bruised blue. I have been seeing this mushroom for quite some time. The stalk is always splitting open, as you can see in one of the pictures. Would greatly appreciate help on this one.

I was going to guess Boletus bicolor, but the cap is not red enough.

What kind of trees are nearby? Can you post a cross section of this mushroom and some pics of some younger specimens?
