    Ganoderma australe & Ganoderma resinceum basal decay Root girdling Inonotus hispidus colonised in the trunk and canopy branches. .

    A tree that has had its time........ Declining ash. Various dysfunctional issues. Park cafe seating area We've monitored this tree over a number of years, its been heavily crown reduced by a previous contractor some years back. .

    I counted at least a dozen Fistulina brackets all over this fine old relic. .

    A fantastic old oak pollard at Wytham wood near Oxford. .

    oak with the basal white rot decay of Inonotus dryadeus & the upper trunk brown rot of Fistulina hepatica. .

    I came across an interesting combination where small saprotrophic white fruit bodies (possibly Marasmius or Delicatula sp) were hosted on the desicating remains of an Inonotus hispidus bracket. The professori thought it most interesting .

    Although now sitting here with a sore head full of a wealth of interesting new facts and information, I found it suprising that there appears (with the greatest respect) to be less interest by the mycologists in bracket fungi on trees than there is regarding the decomposers of fallen wood volumes & the association of the mycorrhizas Bracket fungi appears to be a niche left to non specific - mycologists like David Lonsdale & Ted Green. Why is this? .

    an interesting session at one of the Oxford University field stations today Wytham woods. A work shop with Professor Lynne Boddy from Cardiff University & Dr Andy Taylor from the James Hutton Institute in Aberdeen, on the importance & significance of fungi within Forest Ecology. Well hosted by Earth Watch & the BES The morning program were presentations and discussion on saprotrophic & mycorrhizal fungi & then out for a walk in the woods picking the brains of two of the UK's premier mycologists .

    Stemonitis fusca Its a plasmodial slime mold, not from the fungal kingdom [ame] [/ame] .

    Looks a good shout Tony Interesting that Phillips and Jordon don't mention the 'white' flecks at the edge of the cap, though images on the net (although variable) do show this. .

    Armillaria (as I understand it) is primarily a parasitic fungi that is drawn to and attacks weak hosts. Some tree species are more susceptible to an attack than others. So it will depend on the general vigour of the surrounding trees and the range of species. There will be rhizomorphs of Armillaria in the soil and humous layers. There are ways of getting rid of it, the first is to carry out a complete soil strip ( probably not an option?) another is by using a chemical agent like Armilitox. This second option I would not recommend as this will strip the soil of bacteria and other essential microbes like mycorrhiza Long term, I think the best way to 'control' an Armillaria infection is by creating healthy tree growing conditions with good rooting environment and strip out dead woody material from the immediate area. .

    Next to the Pergola? .

    I think the small orangey ones coming out of the ground are possibly Laccaria laccata, again a mycorrhizal species. The (yellow ones?) in the crack are to small and covered for a proper stab at an Id if they are indeed fruitbody's, but location would lead me to either the saprophytic sulphur tuft or Armillaria. Let's see them when they're more developed. .

    A nibbled Coprinus comatus - lawyers wig/shaggy ink cap, Dean. .
  15. David Humphries
    I would think so. .
  16. David Humphries
    Fungi look to be Paxillus involutus - the brown roll rim, which is a mycorrhizal species Check below the mulch for rhizomorphs of Armillaria. If present, it may be associated with the bleed .

    Any of that Methamphetamine going spare Rab? Looked fun .
  20. David Humphries
    Would of thought that be Malus sylvestris .
  21. David Humphries
    Puzzling Looks a bit like Stropharia aurantiaca - the redhead Roundhead. But they're a ground based fungi as far as I know. Any idea what type and colour the gills were? .
  22. David Humphries
    Look like Armillaria melea, Ross Trace back the bark and see if there are any black bootlaces type Rhizomorphs around .
  23. David Humphries
    Look like Pholiota squarrosa - the shaggy scaly cap Pholiota squarrosa - Shaggy Scalycap - David Humphries’s Fungi Directory - Arbtalk.co.uk | Discussion Forum for Arborists Have you considered the Arbtalk Fungi App? Smart Phone Apps for Arborists - screenshots Designed for this specific field I'd in mind We designed it for this specific type of field I'd query in mind .

    Howdee Paul Just been going through this years presentations as I could only attend on the Monday. First rate group of speakers. Little disappointed that there seemed to be nothing similar to the BBQ & Grahams evening presentation this year. How so? Not deemed successful last year or difficult to get hold of anyone in the same vein? I thought last year, although sadly lacking in contractor numbers on the evening (perhaps further advertising would have helped) really had fantastic potential to engage and get a wider audience attending. What say you Sir ? .
  25. David Humphries
    If they are C. micaceus they're wholly saprophytic and feeding on dysfunctyional roots/root crown The primary reason for decline in health is from another source worth having a probe in the soil for the rhizomorphs of Armillaria .
