    An attempt to help mitigate the habitat loss from the felling of this Inonotus hispidus decayed park ash, we decided to set aside the best of the habitat for resurection in a nearby tree. .

    a scabby London plane in decline. Loads of issues going on, bark cankers and branch die back (but no discernable Massaria noted) This leafless limb was removed in June. Pholiota aurivella fruiting from within the the centre of the cross section from today. .

    Armillaria melea on horse chestnut Amanita muscaria on birch Grifola frondosa on oak Flammulina velutipes on elm .

    Kretzschmaria duesta, one year on and having fruited on the cut surface. .

    Had a trawl, but couldn't find any shots of it during the winter. No pruning works within the last 5 years, other than a bit of dead wood shortening over the paths. The adjacent London planes have been reduced back to stop them encroaching the canopy of the oak. & it used to be unceremoniously 'dumped on' with Oak Processionary Moth pheromone trays back when we used to trap them. .

    Horse chestnut with Armillaria melea Will be interesting to see next years spring flush (if at all) in leaf shots from may last year. out of leaf from this morning. .

    Tbh, I don't have any experience in the field with robusta. Where's your information from regarding the Oak, Schwartz, Butin, Ryvarden? .

    Jules, are you familiar with Duncan Slaters work on unions and biomechanics? http://www.myerscough.ac.uk/downloads/pdfs/Subjects/Arboriculture%20-%20NYTOG/NWTOG11/Slater%20-%20The%20Failure%20of%20Forks.pdf Although this presentation is specifically about forks and failures it is a worthy read to at least see where Duncan has taken Alex Shigo's work on and researched the anotomy of union wood fibres further. .
  22. David Humphries
    Nice Jules Clay soil? Saprobic on just general wood detritus in your garden or anything specific? .
  23. David Humphries
    Just the one stem was subjected to the strike, Guy it's a neighbouring sites tree, not ours. So just a passing observation. .
  24. David Humphries
    Armilaria I would imagine Probably A. Melea There is a enormous amount of fruiting going on currently .
  25. David Humphries
    Look like an Armillaria species to me. Have you got any shots of they gills and stem? .
