my Pleurotus species guesstimates for this observation and its siblings (http://mushroomobserver.org/8461 + http://mushroomobserver.org/58782) have been based on doppelgänger Pleuroti here at MO, nothing more.

when

http://mushroomobserver.org/62383

was listed as P. populinus, I proposed the same for this one. Now that it’s been recombobulated into P. pulmonarius, I’m giving this observation another what-the-hell style naming by proposing the same. someone with some Pleurotus expertise: please put an end to this oyster shooting from the hip. what are these?? I now see that Walk tacked P. albidus onto the other ob which looks like a convincing fit macromorphologically and geographically…

as for Gerronema, I know pitifully little about the genus, but I can’t remember any examples I’ve seen displaying such a cespitose habit. what’s more, these gills were distinctly close, shallow and completely concolorous with the cap. more fitting with Pleurotus somethingus to my mind.
