Excluded from the key above are several North American "species" that were collected once and described by William Murrill in the early part of the 20th Century--and haven't been seen since, except by mycologists who, over the years, have been forced to study Murrill's type collections and brief field notes. I made the mistake of "messing with Murrill" in my key to Pluteus (see Couplet 71 for an example of what results from this mistake), and once was enough.
