Polypores - Non-fleshy texture, stems central or lateral

Some species in this sub-group produce fruitbodies with caps that are thin and leathery, but pliable, whereas other species produce fruitbodies with thick, corky and unpliable caps.

In the following hints you see examples of useful identification features and a few of the more commonly seen genera in which at least some species (not necessarily all) show those features.

Hints

On wood; pores radially elongated: Polyporus.

On wood; whitish cap to a centimetre or so in diameter: Panellus.

On soil; thin, brown, concentrically banded cap: Coltricia.

On soil; thick cap, brown on upper side & with white pores that bruise red: Amauroderma.

Warning

If you think you have a small-pored member of this sub-group, it pays to check with a magnifying glass or hand lens. Some species of the Caps on stems; teeth below caps group produce leathery fruitbodies in which the teeth are so densely packed that, at first glance, you might think the underside has small pores.

Next time be sure to get a clear photo of the underside as it is useful in identification. In this case, the pores are just visible on the underside of some of the ones in the background.

I wonder if this is Pseudoinonotus australiensis (previously in Inonotus, the change in 2022). I’ve seen it just once when I collected it in the Gloucester area of NSW. If you look at the GBIF results for this species (https://www.gbif.org/occurrence/search?taxon_key=2521228) you’ll see that they record only seven other collections, held at the Oslo fungarium. Of course there are probably more elsewhere that either don’t get into GBIF or are misidentified. When I collected mine I assumed it was a large Coltricia. Here (https://www.gbif.org/occurrence/4422619303) you can see a photo of an isotype collection. In this species the underside is not white when fresh and it doesn’t bleed red if you run your fingernail across it.
