They’re both validly published

As to why they’re both “accepted” here on MO, that’s partially because nobody had linked them as synonyms yet. I’ve gone and fixed that. Whether Bresadolia is a good genus is another question. Motato-Vásquez et al. accept Bresadolia as a good genus and find craterellus to be in it, but find that Bresadolia species are only separated from the type species of Polyporus in their cladogram by a group of residual Polyporus species with Cladomeris and Dichomitus nested within. An alternate arrangement would be to have all of these as Polyporus species, which is not without precedent, since all of these genera have previously been considered synonyms of Polyporus.

Re 2 valid names

Thanks for pointing out the duplication.
The answer to your question is:

Because MO handles Names manually. If someone adds a Name and doesn’t notice that MO already has a Name which is a synonym or thinks that both are equally valid, then we end up with 2 Names, possibly unconnected. Because it’s manual mistakes will happen occasionally.

Is this Bresadolia craterella?

I’m confused. If they are the same, why two valid names in MO?
