Species Information
Summary:
Features include a salmon-pink pore surface growing flat on wood, mild taste, and microscopic characters. The online Species Fungorum, accessed April 20, 2020, gave the current name as Rhodonia placenta but Mycobank, accessed the same day gave the current name as Postia placenta. The name in Rhodonia is used here because of the support provided in Shen, L.L.(1) where Rhodonia is separated in the phylogeny from most of Postia. The description is derived from Gilbertson(1) except where noted.
