Specimen available

Growing under oak. These appear to fit the descriptions in Boletes of North America and Mushrooms Demystified very well. Only the second time I’ve seen them. Mykoweb also has a nice picture and description that helped confirm my id.

Not red, but orange, and a perfect fit to the sp. description in the Bessette bolete book.

Going to the hi-res photo, it is apparent that the stipe staining (which did look red) is actually orange.
Great find, Ron.

It’s a fine year for odd boletes AND amanitas.

B. citriniporus?

I don’t know what to call this mushroom…I’ve never seen it in the field. But Roy Halling, in the original protologue states “The pileus of B. citriniporus is umber brown that usually becomes blackish, and the stipe is whitish to pallid, without any reddish to brown coloration.” (Mycologia 69: 207. 1977.)
