      From Ali

      I photo’d this fungus Oct 22 growing on a decaying oak log in a Mid Devon semi ancient mixed deciduous woodland. The closest I could get was the Turban Fungus, but the books say it’s the wrong habitat. The first photo is 5 days earlier than the next 2, it definitely increased in size! It’s about 10cm high and 8cm across. Can anyone advise?

        Welcome to Uk Fungi.

        Can I suggest you don’t give a “desperately needed” title to a photo taken in October? People occasionally come here because their child or puppy has eaten a fungus and they are worried. A title narrowing down the fungus would be more useful.

          Compare with Exidia candida.,

            My apologies, point taken, I’m new to posting on forums, but yes, a bit thoughtless.

              Your fungus has soaked up a lot of water but could be Tremella steidleri, which isn’t common but does like oak. I’ve seen it on oak in Devon. It parasitizes Stereum species which should be visible on the same bit of wood. Exidia candida (var. cartilaginea) is also similar, but prefers birch. I’ve seen it in Scandinavia, but as far as I’m aware it’s not known from the UK. Need a microscope for a definitive answer, I’m afraid.

                Thank you Peter,

                I’ve done a bit of internet checking and it certainly resembles T. steidleri. Even better, the decaying oak log was infested with Stereum hirsutum, albeit at the other end.

                S Hirsutum just visible at far end of log (T steidleri visible in the foreground on left log, between two clumps of moss).

                From the “S. hirsutum end”, (T. steidleri is out of the picture)

                This fungus was really frustrating me so I am truly grateful!
