King oyster mushroom
Also known as Royal Trumpet. This is a huge thick mushroom. The entire thing is edible...stem and all. Slice it about 1/4" thick and toss in some oil and marinade and BBQ it till it's light brown. Meaty texture and kind of nutty flavor. This is a good substitute for the hard to find Porcini as the flavor and texture is very similar.
