    hi Gary, note that species identification means exact species identification. We cannot create species records for " "corticioid fungi" since this is a group of fungi, not a single species. Beautiful find though! Posted 6 years ago

      fchristant,
      Eventually, I hope to get an id on this one. I should note that in its dry state this fungus is a sort of gray-purple color.       Posted 6 years ago

    The fertile surface (the top in this case) looks slightly merulioid? Posted 6 years ago

      It does. The actual upper surface can be just barely seen on other examples of this fungus on the tree where it is growing and is a different color. Posted 6 years ago

        What color/texture were the pilei? Or do you remember?

        The closest I can find is Punctularia strigosozonata?

          The surface texture is a bit vague in my memory but it might be possible to check this tree again soon. Posted 6 years ago

          Not so sure about this being Punctularia based on that first photo. Stereum seems closer but there are possible matches at https://www.flickr.com/photos/31727756@N05/11738696614#!# and #!#http://forum.toadstool.ru/topic/4208-punctularia-strigosozonata/ Posted 6 years ago, modified 6 years ago

            Stereum have a smooth hymenium to my knowledge? I've never seen one with a merulioid fertile surface (the pileus can be wrinkled, however). Please point me to one if you know it! Posted 6 years ago, modified 6 years ago

            I'm pretty sure my ID might be the correct one:
            Just read this note on Punctularia strigosozonata:
            "Substrata: Dead hardwood limbs and trunks, displaying a preference for Populus tremuloides in the study area."

            It seems to show a lot of variation in its morphology More information and photos here:

              That first photo you showed me looked way off and reminded me of Phlebia. Both of these fungi species are growing in the same area on aspen. I'm going to post a photo of this mystery fungus but in its dry state in a few minutes. There is quite a color change. Posted 6 years ago

                Interesting! I agree that the surface looks merulioid and think that Punctularia sp. looks super close for an ID. I'm always impressed by your amazing skills with identifying mushrooms, Lisa! Posted 6 years ago

                  I'm also leaning towards Punctularia. I'll get a look at these fungi this weekend I hope. Snow is a little deep right now. Posted 6 years ago

              Maybe this is a Phlebia? Posted 5 years ago

    Gorgeous shot! The shadowy lighting is perfect for the merulioid surface <3 Posted 6 years ago
