So what's going on here then?

 

Rob,

What tree species ? Aesculus ? If yes, Horse chestnut bleeding canker ? And the fungi are a Coprinus species, which likes tree basis where dogs have urinated on.

[RobArb]

sorry yes, should of stated it was Aesculus.

 

I also knew that its got bleeding canker, there are two more within ten metres also badly infected

 

I also had an incling they were coprinus, guess I should've been brave enough to have a guess myself:blush:

What is it about the urine (just dogs?) they like? I thought Coprinus where final wood decay fungi?

Not just urine of dogs, but urine of all kinds of mammals, including human beings. And of all the more then 100 British Coprinus species, only a few are final wood or wood chips decomposers, the majority lives on humus or nitrogen rich grasslands and soil, fire sites, rotting grass or compost heaps and excrements of cows, sheep, goats, horses, wild boars, deer and roe.

Thanks again, what would the final wood decomposers be, micaceus, disseminatus, atramentarius? Anything near correct?

- C. micaceus s.l., including the species with an ozonium such as C. domesticus s.l., yes.

- C. disseminatus yes, but also on humus rich soil.

- C. atramentarius, yes, but it could also be its look-a-like C. acuminatus.

- on woodchips (and humous soil) : C. plicatilis, C. leiocephalus, C. auricomus, C. lagopus, C. flocculosus, etc.

Thanks again

The plasmodia of myxomycetes have an "open belly" down under, with which the substrate is "grazed" for organic materials (bacteria, algae, spores and hyphae of fungi, rotting plant debris, etc.). Indigestible parts and dead parts of the myxomycete are left behind in the silvery "snail sliding trails", which follow the tracks of the plasmodium while moving about.

 

And this is what the 25 x magnified sporangia of Physarum cinereum with white lime deposites on a Hedera leaf through my new photo and video microscope look like.
