Recognized by sight: This mycorrhizal fungus seems to be specific in our area with various native and introduced birch species. I rarely/seldom find Paxillus associated with any other tree in Oregon. I have grown this, back in 1987. I had a seedling birch which was dropped, probably by a bird, from a tree about 3 blocks from my house. The tree grew too close to the house, so had to be removed about 1991. But before that time I had several flushes of Paxillus involutus in my front yard, within 2-4 yards of this tree. While many question whether mycorrhizal fungi can be grown, this was the second species (after Scleroderma) that I cultivated on my property. I thought it was rather easy to grow. But first I contacted several people at the Oregon Mycological Society to verify where they had seen Paxillus involutus. Almost to a person, they said “birch.”
