Amanita regalis
''Amanita regalis'', commonly known as the royal fly agaric or the king of Sweden Amanita, is a species of fungus in the Amanitaceae family. Common in Scandinavian countries, it is also found in eastern and northern Europe. In North America, its distribution is restricted to Alaska. The fruit bodies of the fungus somewhat resemble the fly agaric (''Amanita muscaria''), and it was formerly regarded as a variety of this species. ''A. regalis'' differs from it in being larger, with a liver-brown cap bearing numerous scabs, and in having a stem which is yellow-ochre at the base, with patches or rings of patches. Chemical analysis has shown that this species contains muscimol, the same psychoactive compound found in ''A. muscaria''.
==Taxonomy and naming==
''Amanita regalis'' was first described as ''Agaricus muscarius'' β ''regalis'' by Elias Magnus Fries in his ''Systema Mycologicum'', published in 1821.〔 In 1887, Pier Andrea Saccardo treated it as a variety of ''Amanita muscaria''.〔 Edmund Michael, in 1903, became the first to consider it a distinct species.〔 In 1941, Jean-Edouard Gilbert suggested a complete reorganization of the genus ''Amanita'' in his world monograph of the genus, and moved it to ''Amanitaria'' as ''A. muscaria'' var. ''regalis''.〔 In his original (1949) version of ''Agaricales in Modern Taxonomy'', Rolf Singer considered it a subspecies of ''A. muscaria'', but noted that it may be regarded as a separate species; in the fourth edition (1986), he listed it as a distinct species.〔 ''A. regalis'' is classified in a section of ''Amanita'' within the genus, a grouping of related Amanitas that have a ring on the stem (or remnants thereof), and a bulb at the base of it.〔Jenkins (1986), p. 16.〕 More recently, a Japanese group studied the biogeography of ''A. muscaria'' and related species, and, using molecular phylogenetic analysis, concluded that the taxon should be considered a grouping of ''A. muscaria'', rather than a distinct species.〔 However, as of 2012, both Index Fungorum and MycoBank list the taxon as ''Amanita regalis''.〔〔
The species has been called by several vernacular names, including the "Brown fly agaric",〔 the "king of Sweden Amanita",〔 or the king fly agaric.〔 In France it is known as ''Amanite royale'',〔 while in Germany it is ''Königsfliegenpilz''.〔 The specific epithet is derived from the Latin word ''regalis'', meaning "royal".〔 In 2000, it was selected by the German Mycological Society as "Mushroom of the Year".〔
