FYI: seems like the new name is "Merulius tremellosus", so updated the species record. Superb photos and documentation! Posted 3 years ago

  Merulius tremellosus is the old, deprecated name:

    Hmmmm, it seems not all systems agree:

    Note "Merulius tremellosus" striked through as name to not use anymore. I honestly don't know who would be the authoritative source in this matter. Posted 3 years ago

      I have no clue which is correct. I trust MO since they are mushroom people, but I would think that iNat would be using the correct name. I don't know the answer, but think that leaving it as is should be fine for now, right? Maybe someone can confirm/correct us. I can ask a mushroom person? Posted 3 years ago

        It was first described as Merulius. It was transferred to the genera Cantharellus (1832), Sesia (1891), Byssomerulius (1974), and then renamed as a form of Merulius. It was then transferred to Phlebia in 1984 when Nakasone and Burdsall made Merulius with Phlebia synonymous. Just recently, some taxonomists have shifted this particular species back to Merulius (but have not moved several other Phlebia which belong in the same genus).
        
        It's a complicated mess, and taxonomists can't seem to agree on anything.At this point, most experts I talk to are saying Phlebia and Merulius are synonymous. So either works. Posted 3 years ago, modified 3 years ago

        Thanks so much for the info, Lisa. Mushroom taxonomy is so confusing! Posted 3 years ago

        This is from what I've gathered :D Not sure how accurate. Feel free to search for more info. I agree, it is very confusing. Most experts I see posting observations will include both Phlebia and Merulius in their descriptions. Posted 3 years ago, modified 3 years ago
