About the only thing I find P. involutus with is birch. In fact, when I am looking for this species, I zero in on birch, especially our native Water birch, which can sometimes be found along the Columbia River.
BTW, be on the lookout for Tuber species with Tilia: there is a species which can be found from now through early May, and seems to be resistant to freezes as well.
Not within sight. I have been seeing them fruit under trees they normally don’t fruit under this year, while the Birches I have seen them under in the past right now have none.
This observation was under Tilia, with no Birch in sight as well:
is a common ornamental planting in my area. But I have never found P. involutus associated with it. Rather, I have grown it with seedling birch in my front yard (several years ago), and have collected it many times under a single birch in the courtyard of the Oregon Historical Society Museum.
In my personal experience, it can fruit quite a distance from the host plant. If, for example, a birch tree is 30 feet tall, P. involutus may be fruiting 20 feet distant from it.
What tree was growing nearby, Tim? If birch was present, almost guaranteed P. involutus.
