chrysophlebius / admirabilis

there has been some historical confusion surrounding the names chrysophlebius and admirabilis. Minnis & Sundberg based on morphological data and the historical usage of the names came to the conclusion that the name chrysophlebius should be used. You can check their article here


From the molecular point of view there are some minor differences on the collections from North America, Europe and Asia. For now the sampling is quite limited and we are still unsure if those differences warrant recognition of different taxa. In any case the North American chrysophlebius/admirabilis represents one single entity for which the name chrysophlebius will be used regardless of what happens with non-American collections. A bit more about the molecular complexities of this group here:


P. leoninus has a different texture of the cap. The stipe can be yellow or white in leoninus, but usually not that bright yellow and not the full length of the stipe. Microscopically they are quite different.

P. leoninus as having a white stipe. (My original comment misquoted this assertion; I have edited.) The ones in this obs have yellow stipes.

this could be Pluteus leoninus—see obs 142334.


Thanks Fredo.

I had forgotten the currently acceptable name for what had previously been called P. admirabilis here in northeast NA. I wonder just how much confusion currently surrounds the use of these names? MushroomExpert mentions P. chrysophlebius as a look-alike species for P. admirabilis. Have the species names admirabilis and chrysophlebius been lumped for some broad geographic range?
