Notes: Fruiting from same Abies grandis snag as original conk, which has fallen off (http://mushroomobserver.org/116383?q=2g4ag).

Compare to Ganoderma brownii, not sure how diverse its range of hosts is. Ganoderma tend not to be too specific anyways, there are trends but no absolutes. I get the Eastern variety of G.applanatum on Hemlock here in New York quite often. I suggest G.brownii because I think it tends to have a different pileus surface than G.applanatum. Though I haven’t had any proper examples to study yet.
You can determine whether it is Ganoderma or not when the spores come out. A brown spore deposit is a good indication of Ganoderma, under the microscope Ganoderma spores have a distinct doublewalled structure. Spore size will help narrow the species down even further, G.brownii has larger spores than G. applanatum.
Multiple polypore species can inhabit the same wood at the same time, it is common for Ganoderma and Trametes to fruit together. I have a photo someone sent to me of G.tsugae and Fomitopsis pinicola fruiting from the same stump. I also have G.applanatum and Fomes excavatus growing together in the woods out back. More than one Ganoderma can also inhabit the same tree, see my observations 222803, and 220185
but that might be a function of being a young fruitbody.
There are a few Ganoderma that regularly grow on conifers, but most are in the red-shiny-capped (varnished) group, not these dull brown Elfvingia-types.
But perhaps they have a broad enough host range to take in a well-rotted grand fir.
As for dynamics of succession – I wish I had a clue.
I wonder then, did this Ganoderma colonize the decayed snag after Bridgeoporus had run its course, or were they both present at the same time? Assuming that Bridgeoporus was in fact present here to begin with (we observed a very large, decaying polypore on the ground with Oxalis growing from the top, at a location with a previous Bridgeoporus observation).
Also, if anyone wants to point in the specific direction of a conifer-consuming species of Ganoderma with large, semi-angular basal pores and a hirsute pileal surface, that would be swell.
