Possibly a Ganoderma?

Is that in the applanatum key?
Its similar to G.applanatum in appearance, but microscopically it has larger pores and a slightly different skin structure. DNA has been confusing for me, either because I don't know enough about the phylogenetic program I use or because Ganoderma genetics are screwy.
With non laccate Ganoderma it seems that there are two main groups, the G.applanatum group has the smaller spores, typically a smoother pileus, lighter in color usually shades of grey or light browns, darker when wet. A second group would be the G.adspersum group, this includes species like G.adspersum of Europe, G.lobatum and G.brownii of North America and G.australe from the southern hemisphere, they are characterized by having larger spores, a darker rougher pileus surface. Common sense would dictate that on a phylogenetic tree these two groups should group together on the same branch seeing as how they have a lot of similarities. Not shiny, typically perennial though lobatum is anual, and with a pileus that is made of of thickened intertwined hyphae compared to shiny Ganoderma which have a pileus made up of thickened rod shaped cells that are stacked up like fence posts. But when I build phylogenetic trees from DNA sequences they always seem to form two separate clades that never seem to group together, but I suspect it is an error on my part.
So G.lobatum is best described as being a member of the G.adspersum complex, rather than G.applanatum complex.
The G.applanatum complex itself is interesting, there are significant morphological differences between geographically isolated populations. The most interesting is the variety that grows on the West coast in the forests of the Pacific Northwest. This one likes to grow in a stacked shape, looking similar to a stack of pancakes and is sometimes confused for Laricifomes officinallis. It has this weird trait where after a year or two the flesh will start to turn white, in older specimens the bulk of the inside may be completely white, safe for this years pores which will be brown, its skin color is often a yellowish brown. On the East coast you have another variety which some people have taken to calling Ganoderma megaloma, which more closely resembles G.applanatum from Europe, it usually grows more flat as opposed to stacked its skin is a lighter color, sometimes almost greyish white, but can be darker. What really separates it from the European G.applanatum sensu stricto though is it has a sterile band that grows around the outside edge of the pore surface. This band can sometimes be quite thick. The flesh is a medium to dark brown. Neither the West Coast variety or the European varieties have this sterile band.
The interesting thing is though, all three varieties cant be distinguished microscopically, the spores are all the same size and the make up of the cells in the pileus are the same. DNA is not very helpful either, at least the sequences I got from Genbank showed no geographic grouping whatsoever. I think separating them as separate varieties would probably be a good idea.
G.lobatum is also interesting because it is an annual species as opposed to G.applanatum and even other members of the adspersum clade which are perennial. You can often find new conks of G.lobatum growing directly under the previous years conks, but not physically connected, the previous growth being black and decomposing. It does not grow in layers like you find in applanatum.
