''Lactifluus'' is a genus of mushroom-producing fungi. It is one of three genera containing species commonly named milk-caps, the others being ''Lactarius'' and ''Multifurca''. It has been separated from ''Lactarius'' based on molecular phylogenetic evidence and is very similar to that genus. ''Lactifluus'' species have a mainly tropical distribution, but are also found in the north temperate zone as well as Australia and New Zealand. ==Systematics and taxonomy== |2=''Lactifluus''}} |caption=Phylogenetic relationships of ''Lactarius'', ''Lactifluus'', ''Multifurca'', and ''Russula''.〔 }} The genus ''Lactifluus'' was described in 1806 by French naturalist Henri François Anne de Roussel, with the type species ''Lactifluus piperatus''.〔 Later, ''Lactifluus'' was largely considered a synonym of ''Lactarius'', until molecular phylogenetic work showed in 2008 that ''Lactarius'' was not a monophyletic group.〔 In the following, the name ''Lactarius'' was conserved for the biggest of the subclades revealed, containing most well-known north temperate species.〔〔〔 Thus, the name ''Lactifluus'' could be used for the smaller genus, necessitating only a few name changes, as combinations with ''Lactifluus'' had already been made previously for many temperate species.〔〔 New combinations have since been proposed for several species formerly classified in ''Lactarius''.〔〔〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lactifluus」の詳細全文を読む スポンサード リンク
