Fungi Id help on macrocarpa please

[Danavan]

Working for a fella a week or few ago & one of the jobs for the day was to remove several macrocarpa due to decline in their condition & some dead ones. Came across this fungi body on the base of most of the trees & I am thinking that they may be suffering from Coniophora puteana?

 

If this is the case is this curtains for the lot of them & is their any treatment that can prevent the spread of it i.e urea treatment of the stumps as with other conifer butt rot fungi?

spo on fella, but would not accuse the C. puteana as the cause, just a symptom of dysfunctional tissue, Armillaria is the pathogen here IMO

[Danavan]

Thanks hama, I did spot some armillaria spp loitering around a mature sycamore that is just in the frame to the right.

 

I found no bootlace or other fruiting body's around the trees I felled. Is this just because the damage being done is happy enough feeding out of site for the moment?

Danavan,

I'm not convinced this is a Coniophora species. It could just as well be one of a number of look-a-likes, that can only be identified 100 % certain with a microscope.

Cheers Gerrit,

 

The rot that I saw was indicative of brown rot as far as I can remember. It rotted the stem from the inside out. As C. puteana is saprophytic can it rot wood in this way as a secondary infection previously weakened by a more aggressive pathogen?

 

If it is not C. putena spp is it an amophous body of another spp?

Hard to be precise from the image but the crown symptoms look similar to those caused by Coryneum canker (seiridium cardinale (as well as a variety of other causes too I guess)) p107 of Strouts & Winter has a good description.

 

The Monterey cypresses down my way and particularly in Torbay have been hammered by this throughout the last decade or so resulting in the removal of many.

 

Cheers, Dave

it would make sense, weakened by this the armillaria would move in quickly

Thanks davyjones,

 

I will look for this one in my limited pest & diseases books as well as the online fungi directory for more info as well as other on line sources on this one as my knowledge is low in many factions in this area at present.
