Here’s another species of bolete in the easily recognizable Suillus genus that grows in the Larch forests around Seeley Lake. Again, this species of Suillus is an ectomycorrhizal symbiont with Larch. (I should note that not all members of this genus are associated with Larch, but when you’re hunting for mushrooms in a Larch forest, you tend to find Larch symbionts). This species, unlike the others I’ve posted so far, has a slimy or viscid cap. This slime is known to cause gastrointestinal problems for those adventurous enough to attempt to eat these fungi, so be sure to remove the outer layer prior to preparation. Unfortunately, Greville’s Bolete is said to have no flavor and a generally mushy consistency when cooked, so I just wouldn’t recommend it.
