“pink oyster” works for me.

referenced in a name proposal over at Observation 33575, is a synonym of P. djamor and P. ostreatoroseus. The page for P. djamor var. roseus has no info on synonymy, but I strongly suspect they’re all the same.

has a ridiculous number of synonyms on IF, but ostreatoroseus isn’t currently one of them.


BTW, here’s a random, cool video of P. djamor fruiting from a trashy paperback novel in time lapse, courtesy of Cornell:

My knowledge of the newer of the two names comes from The Agarics of São Paulo, Brazil by Pegler, in which the only key choice for a pink Pleurotus is this taxon. I’ve not yet tracked down Singer’s description (Pleurotus ostreatoroseus Singer, Publções Inst. Micol. Recife 304: 10 (1961)), but there is one of P. djamor var. roseus in The Genus Pleurotus in Argentina (http://www.mycologia.org/content/96/4/845.full.pdf pg. 852). I suspect they’re synonymous, but once we have both descriptions we can compare for ourselves.

what are the diagnostic characters for these two? (dja v. rose and ostr-rose)
