    He is pretty sure it is Suillus granulatus.

    if there’s a slight pink tinge to the base of the stem (pink hyphae) then it’s likely to be collinitis, if there isn’t any pink, then probably granulatus

    Base of False Acacia.

     

    Aurantiporus fissilis?

    Its not Aurantiporus, its either going to be Ganoderma resinaceum or Perenniporia fraxinea. I think its likely to be the latter. Ideally a wedge of the flesh and tubes would be needed to confirm. Also look for spore deposit on the leaves or webs. Ganoderma will be cocoa brown, Perenniporia will be cream/white.

  3. Probably Inonotus hispidus (Shaggy polypore)

     

    Depending on the level of occupancy around the immeadiate vicinity of the tree, I suggest you have it assessed by a professional Arborist that has access to the knowledge and equipment required to undertake assessment of potential basal decay and any associated stability issues.

  4. I suspect this is Ganoderma adspersum.
     
    The dark brown flesh in the 3rd image rules out Phellinus or Fomes.
     
    The white surface in your 3rd inage  is a feature of Ganoderma, whereas the under surface of Phellinus is a tan brown colour.
     
    I also think I can see cocoa coloured spore on the edge of the cobweb in the 3rd image. 
     
    Do you have a copy of the AA Fungi on Trees photographic reference book?
     
    On page 77 in the section on perennial fruit bodies, image 4 (going clockwise) shows a tired bracket of G. adspersum that has a surface like your old fruit bodies which also shows a wedge of the flesh on top which is a close match to your 3rd image. 
     
    Hope you find this helpful. 
  5. Might be worth looking at the soil for contamination, trowel out some volume and have a smell. Could be that oil, diesel or some other chem has been ‘accidently’ allowed to escape into the soil horizon in that part of the root zone and killed off the roots leading to sectional dysfunction/dieback.

     

    What’s the history of the site use in that particular area?

     

    How long has that street light been there, looks relatively recent.
