Pleurotus angustatus

An old oyster-type name (Saccardo 1887) with an 1867 collection from Sri Lanka, applied in North America to a small Pleurotus on rotten hardwood logs, mostly collected in Michigan and around Gainesville, Florida. It is not cultivated, and whether the Asian and American collections are the same species is doubtful.
