Most probably a young Hydnellum peckii, and the ‘goo’ is most probably aurantiacin or thelephoric acid, which has been used for centuries to dye wool. Later on, the fungus would’ve developed the sharp structures that give it the ‘tooth’ part of its name.

  1. Like colored syrup oozing out of it. Different colors, different amounts. It was weird, man!

    Some kinda alien marshmallow fell to earth.

  2. That’s a very young hydnellum peckii. It’s common names include "bloody tooth". An amazing mushroom, but not good to eat – you wouldn’t get past the bad smell and taste anyway.

  3. LOL goo!

    And dogsbody, thanks so much! I’ve shown that pic around even at the university and no one could tell me what it was! Appreciate it! I’ll add that to the description.

  4. Further research (mainly the wonderful Tom Volk’s mushroom pages) reveals that it is definitely in the Hydnellum genus and may be the one dogsbody said, but – as i’m sure he will admit, there are 15 Hydnellum species and species determination can be tricky.

    It turns out that the ‘goo’ is most probably aurantiacin acid, which has been used to dye wool.

  5. Hi Zen. You’re very welcome. I just happened to remember seeing it in one of my mushroom books and looked it up again. I make it a point to keep as little in my actual head as possible.

    And my book also said that the red goo (aurantiacin acid if you insist) is used to make blue and green dye. I’m sure that makes sense to someone.

    Thanks for the photo and the discussion!

  6. I should credit my source: David Arora’s excellent pocket guide to Western mushrooms, entitled All That the Rain Promises and More… I don’t go into the woods without it.
