Recognized by sight: So far as I know this is the only Pycnoporus in South America (and the only orange one). But I don’t know enough about South American polypores to be sure. The funny looking side structures are fruiting bodies that formed after the stick/ log was turned, since the spore dispersal depends on the pores being aligned with gravity. Beautiful specimen.

Pycnoporus cinnabarinus, sanguineus and coccineus. Neither does like look this IMO … I also do not detect any pores …

I see no pores…

An admirable, eyecatching polypore.

If more polypores looked like this one, they would be more eagerly sought and named!

Looks more like Pycnoporus to me

I would guess the cause of the funny side growths is that the stick it’s growing on got turned. I’ve seen other polypores create structures like this when that happens.

I was wondering if you looked at the underside… It appears that it could be smooth which would make it something like a stereum… if not though I would imagine it would be a pychnoporellus species…
