Identification: Fungus (?) on a tree ID needed

hello folks,

I came across a tree that drew my attention because had on it
somewhat that resembled like a fungus or slime mould growing on
it. On a closer look, there were several insect walking around that
strange "thing" so I thought it could have also been their nest,
so not a real fungus...I poked that thing with a stick, and it
was not really hard yet not gelatinous.

 

not easy to identify without micro charachters.

seems really close to that photo : http://www.flickr.com/photo_zoom.gne?id=190480832&size=l

which has been labeled as Fuligo Septica (however, it may have been classified wrong).

What if I take a small piece of that (1-2cm) and place it on a wet petri dish with oat ?

 

Not easy from fungi that grows on trees. Sure your one and the flickr one isn't fuligo septica.

Your one maybe Phlebia cornea or a young other fungus. If you can return to the same trees ... after 15 days...we can see other caratheristics.

Sorry for my horrible english!

thank you...yes when I came back to the tree, the fungus turned brown and somewhat
dry-powdered... any guess about that?

thank you all in advance
