''pubescens'' by Gillet in 1876)〔 and as both a subspecies (as ''Lactarius torminosus'' subsp. ''pubescens'' by Paul Konrad and André Maublanc in 1935)〔 and a variety (as ''L. torminosus'' var. ''pubescens'' by Lundell in 1956)〔 of ''Lactarius torminosus''.〔 ''Lactarius pubescens'' is classified in the section ''Piperites'', subsection ''Piperites''. This includes related ''Lactarius'' species characterized by having a latex that does not become yellow upon exposure to air, and which does not stain freshly cut surfaces of the fruit body yellow.〔Hesler & Smith, 1979, p. 237.〕 Based on phylogenetic analysis published in 2004, ''L. pubescens'' is most closely related to ''L. scoticus'' and ''L. tesquorum''.〔 The mushroom is commonly known as the "downy milkcap". The specific epithet ''pubescens'' is derived from Latin, and means "becoming downy".〔 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「Lactarius pubescens」の詳細全文を読む スポンサード リンク
