Tells: Very distinctive red/brown scales all over the cap. Likes White Pine. Yellow pores age to brown, stain red-brown, & can be huge.
Other Information: The cap is by far the most distinctive feature. Stem may have a grayish ring. Yellow cap flesh DNS or may redden just a bit.
Science Notes: DNA testing has led the authorities to move this mushroom back from the well known “pictus” name to the older spraguii. Whatever the name, it is an eastern counterpart to the equally common, genetically distinct west coast mushroom Suillus lakeii.
