This was previously listed as deprecated in favor of S. fasciatum based on a brief comment in Arora’s Mushrooms Demystified, 2nd Ed. Based on Index Fungorum Stereum fasciatum is the one that should be deprecated in favor of S. ostrea.
According to Ryvarden’s monograph “Sterioid fungi of America”, Stereum ostrea and Stereum fasciatum are synonyms of Stereum versicolor, a tropical species. The temperate taxa is Stereum atrorubrum. To quote Ryvarden about S. versicolor: “Replaced by S. atrorubrum in temperate zones, which could easily be interpreted as a form of S. versicolor, although the latter has pseudoacanthocystidia.” (M.
