    Decay images

    Having picked up on something Tony said yesterday & seeing Tom was asking for atypical images of Merip root decay, thought it would be good idea to get a set of shots together in one place for reference. Here's some of the white rot in roots of Beech, associated with Meripilus giganteus. .

    Fairly common Will, but only if you had the pleasure of seeing them and bagged them in their particular habitat.
  3. What have you seen out there recently? What are you seeing more of this year? Is there anything new and unidentified out there?

    Schizophyllum commune - Split Gills

    Fungi Id please

    Not 100% sure it’s Laccaria, but not sure what else it may be to be honest. Laccaria’s are mycorrhizal

    Fungi Id please

    Has a look of Laccaria laccata or L. proxima but the gill attachment looks a bit odd and difficult to see with these images. Were you on the beer 😄 Were the gills relatively flat under the cap (adnate) or attached lower down the stem? (decurrent)

    Decay images

    Hi Nick, how’s tricks? Any shots of the context of the tree? Also interested to know if you had any decay assessment undertaken? Fine set of images. Strong band of reaction at the edge of the decay evident.

    Decay images

    Fomitoporia but used to be known as Phellinus. Similar to Phellinus pomaceus. Pretty sure it’s not in Jordan’s. Not many of the fungi Id books list it as it’s seldom noted. Think Ryvarden has it listed in his Europe’s Polypore volumes. Don’t think I saw your message, was it here on AT or on my work email? Can you send it again.

    Decay images

    Fomitiporia punctata (Karst).Murrill. Colleague and I were invited down by a neighbouring local authority to witness the section dismantle of a London plane street pollard with suspected colonisation of F. punctata (previously known as Phellinus punctatus) It was an interesting opportunity to observe the spread of the decay from impact damage and prunning wounds into the core of the wood volume and breaking the through the trees codit barriers. Not much literature I can find on the ecology and significance of the species on this particular host tree but we believe we are seeing evidence of white rot delignification. First image is a google street view of the tree from 2008, second image clearly shows the dysfunctonal bark on the right hand side of the trunk, associating with the dysfunction and decay. There also appear to be canker type strips flowing down the trunk below the fruit bodys, where the incramental live wood has been unable to occlude the dysfunctional xylem. Samples from this tree and control trees further down the avenue are being sent to Forest Research for further annalysis to assess the wood volumes for other wood decay organisms.

    Fungi ID on Atlas cedar trunk

    Hi Pat, to be honest there is no specification as each tree will be vastly different In terms of root morphology and growing environment. You’re pretty much on the money. Excavate the soil by hand with small spade/trowel around all the main butresses (or where there is a specific fruiting) being careful not to damage root bark. Checking for decay and dysfunction using a sounding mallet and probe. Be aware of any live cables.

    Hand dig or airspade investigation. Either option will potentially give you more knowledge of the root/buttress condition.

    Fungi ID on Atlas cedar trunk

    Could be dead bark, could be dysfunctional xylem/phloem. Have you looked at or considered excavating around the trunk/root interface to assess the root vitality?

    Looks a bit like Coniophora puteana

    Think you're looking at Trametes versicolor Phaeolus schweinitzii on the stump Ganoderma sp on the cherry Brefeldia maxima on the twig and something like Otidea onotica on the mulch

    Yep oak, been sitting about 4 years I think.

    Psathyrella species perhaps but there are 400 species to choose from. Could be something entirely different of course. Basic ident features like gills and spore print would be useful.

    Target the areas where you find fruit bodies.

    Found this on willow that is clearly dying! Any ideas?

    Arb Associations Fungi on Trees is a good start, though limited to the 25 principal most commonly found species. Buy a general fubgi Id book (Jordan, Phillips, etc....) Join the British Mycological Society. Find your nearest local mycology group and go out on forays. Visit different woodland sites than your used to to find more unusual species. Build your own digital reference resource with species specific folders. Look at and catalogue tree failures you come across at work and other sites. Fungi identification is a long but very interesting road.

    Airspading is one option. Uncovering the roots with compressed air and ‘sounding’ the roots to listen for wood density/function/decay. Can also use a spade ’carefully’. There are other detection techs available, but I have no experience of those.
  22. David Humphries

    Yes in a way because it’s a true saprophyte so it is devouring dead roots. The dead decaying unstable roots are the real issue, not specifically the fungus.

    Look like one of the tufts - look at Hypholoma fasciculare
