Personal Experience

When I first saw this mushroom from a short distance, I was sure that it was something that was already well into its decomposing stage. However upon closer inspection it became clear that the black, textured appearance was its natural look. Having had good experience with Boletes up until that point, I was also greatly surprised to learn that it was part of the Bolete family and edible at that! To date I have only come across two of these during separate times, and have not had the chance to try eating it. The first time I didn’t know what it was, and the second time it wasn’t a fresh enough specimen. However given the large pores/tubes, I suspect it will shrink quite a bit and offer more of a slimy cooked texture.
