any help with id's on these would be appreciated

the bottom one looks like a natural sponge or honeycombe, is nestled on the ground between roots and a few weeks ago was bleeding a syrupy looking goo.

 

 

they are all hosting on this magnificent red oak which must be one of the oldest in the country. i tell you it looks spectacular when in leaf and has a dbh of 5' 6"

I'd guess

1 Ganoderma pfeifferi - Bees wax bracket - David Humphries’s Fungi Directory - Arbtalk.co.uk | Discussion Forum for Arborists

2 ?

3 4 Ganoderma australe (adspersum) - Southern bracket - David Humphries’s Fungi Directory - Arbtalk.co.uk | Discussion Forum for Arborists

5 Inonotus dryadeus - David Humphries’s Fungi Directory - Arbtalk.co.uk | Discussion Forum for Arborists

I'd say 1&2 are more likely to be G. resinaceum. I reckon australe is a good call and the last is definitely I. dryadeus.

Is the tree being managed? Looks a large crown for a bad combination of fungi on that tree species..

[se7enthdevil]

i should have explained that pics 1-2 are two views of the same bracket, as are 3-4 two views of the same bracket.

 

 

do any of these fungi spell doom for this magnificent tree???

 

 

 

it is managed and did have a large limb taken off it last year as it had some rot in, and why can it not have too large a crown???

 

if it survived 1987 and last month both with 70-80mph winds in our area fully leaved surely the tree is sound is it not???

First thing that came in my head for first one was G. pfeifferi but I have never positively ID'ed that one before as I haven't knowingly encountered it.

Resinaceum and australe (assuming it is australe and not lipsiense) are two of most 'aggressive' Ganoderma on Quercus species; anything other than our native Quercus have a real hard time with it. Many oaks cope well with dryadeus.

It's impossible to say without seeing the tree in person what extent of decay there might be. Generally a large un reduced crown creates a large 'sail effect', placing more leverage on the stem = higher chance of failure, hence why the oldest trees are old pollards. It's a balancing act between reducing the stress on the decayed stem/roots, and, leaving leaves for photosynthesis/minimal pruning wounds.

So the tree may be knackered, further weakened by the recent gales, or it may stand for decades. But, it might need a helping hand from the pruning saw to significantly extend its otherwise natural life expectancy.

 

Nice tree
