Bjerkandera adusta on Weeping Aspen tree

Hi, i am trying to identify a bracket fungus that is growing on a weeping aspen, Populus tremula 'pendula'.
through some basic ID/photo cross referencing (i couldnt get any spore prints) i think it may well be the white-rot fungus Bjerkandera adusta. anyone any thoughts? it seems this fungus likes to fruit from wounds on the stem or branches and it seems this is the case in my photos.
thanks for your help.

i look like it also any other polyporus sp. , is very dificult to id poliporus sometimes maybe a good close up of the pores of the undercap and the color of the cap can help , is a poliporus for sure. maybe is in pin size yet it will grow more .. all my best , is any drop of juice around the mushrooms what color just in case. never seem populus juice.......

Rodgers, in the link you supplied, says that the taste of B. adusta is sour, that is somewhat unusual for a polypore. Does the polypore you found taste sour?

Well i went and had another look this morning. the taste was more bitter than sour. there is alot of moisture around the fungi and bark wounds/cracks, it seems to be water, with no obvious colour tint.
as you can see from the photos, the underside of the pores has a grey sheen, which bruises black. there is also a brown/tan zone at the edge of the bracket, which i assume is the newest growth.
basically i am trying to figure out if this fungi is saprophytic or some type of white-rot fungi which is invading the tree. am i right in thinking that this is more than liekly going to be a white-rot, ie: a lignin and cellulose/hemi-celllulose degrader?
thanks

all white rot or black rot or other color are same saprophytic fungus is just some degrade ligning and other degrade celulocic or both don´t remenber quite good, if your concert is if is going to kill the tree well it is,. for the white micelium in the picture i can say is a white rot fungus, stereum come to mind also , there´s no much you can do you if you like to save the tree, but you can try or let it go as natural he can live for many year more until the mushroom wins the battle..
is your mushrooms soofh or hard , cut a mushrooms in 2 to see tubes or some structure of the pores how spaced are the pore in a mm (milimiters) i found this :The brown rot fungi, which attack mostly softwoods (conifers), produce cellulase enzymes that digest the cellulose and hemicellulose in the cell wall but leave the lignin largely unaffected. The result is decayed wood that is some shade of brown and that, in an advanced stage, may be stringy, have pockets, or may crack into a cubical pattern. The decayed wood then becomes crumbly. The white rot fungi enzymatically digest both cellulose and lignin and reduce the wood to a light-colored, spongy, or stringy mass with white pockets or streaks separated by thin areas of firm wood. White rot fungi commonly attack hardwoods (deciduous trees) that are normally resistant to brown rot fungi. Some Ascomycetes cause a relatively slow white rot with variable black zone lines in and around the rotting wood both in standing hardwood trees and in slash. In standing trees the decay is usually associated with wounds or cankers. from here http://ipm.uiuc.edu/diseases/series600/rpd642/index.html http://www.extension.umn.edu/distribution/horticulture/DG6659.html#Poe is more information about populus diseases

thanks cactu  the mushrooms are fleshy, but tough (not tough like a ganoderma!). you have to snap them with force.
there is about 20-25 pores / mm2. (measured with ruler/magnifying glass/eyes!)

It is sounding and looking more and more like B. adusta. Nice pictures and good description. B. ajusta, I think, is a white rotter, Bjerkandera+white+rot, the only thing that doesn't match is the sour taste.

aye, i'm pretty sure its B. adusta as well. according to a study in 1990 this fungus likes causing longitudinal splits in P. tremula wood. and i'd already diagnosed this tree as having longitudinal splits in its 3 branches, right above the fruiting bodies so it kinda fits, i hope!
