Mixed collection?

I’m not convinced that the larger shelf-like specimen and the flatter grayish specimens are the same species. The white one reminds me of Trametes gibbosa. If it were Bjerkandera, it should have pores with at least a hint of brown or gray and bruise blackish when fresh, and age to a grey or brown color. The flatter ones looks like they could be deformed Bjerkandera to me, though.

How about something like Oligoporus

Nice photos. With something this diverse, I like to provide some shots showing the whole log or parts of the log. It is also nice to wait a few weeks after the first set of photos and watch what happens. You can date the photos separately, then we can see how they have grown. A view of the top of the shelf would be good, too. By the way, I have got my eye on some very strange blobs growing on logs right now.

around that time i was seeing a load of those brackets, but that is the only case of those mounds I found. they did appear very similar to the brackets (but obviously different). I don’t know anything about kretzschmaria deusta, but the MO observations for it all seem to be rather flat, while these were definitely protruding.

The first image looks a little like Kretzschmaria deusta, but that species grows as a lumpy crust, rather than forming brackets or other shapes, which makes me think this is something else.
