Lepiota clypeolaria commonly known as the shield dapperling or the shaggy-stalked Lepiota, is a common, toxic mushroom in the genus ''Lepiota''. It is widely distributed in northern temperate zones, where it grows in deciduous and coniferous forest. Fruit bodies have a brownish cap, a shaggy stipe with a collapsed, sheathing ring or ring zone, and spindle-shaped spores. ==Taxonomy== The species was first described in 1789 as ''Agaricus clypeolarius'' by French mycologist Jean Baptiste Francois Bulliard. Paul Kummer transferred it to ''Lepiota'' in 1871.〔 It is commonly known as the "shaggy-stalked Lepiota".〔 ==Description== The cap is egg-shaped when young, soon broadly bell-shaped and has pale straw- or orange-brown scales on a pale background. The central umbo is covered with a well-delimited uniform disk of the same colour as the scales. It grows to a diameter of . The gills are white, crowded, free from attachment to the stipe.〔 The white stem has an indistinct ring, below which it is coarsely woolly, giving an appearance which is sometimes described as "booted". The stipe, which measures long by thick, is hollow and slender, expanding slightly at the base into a club shape. The flesh is white and has an unpleasant smell.〔 The spore print is white. spores are fuse-shaped (fusiform), meaning that they are tapered at both ends. They have dimensions of 12–16 by 5–6 µm. Cystidia on the gill edge (cheilocystidia) are club-shaped to cylindrical, and measure 20–40 by 5–15 µm.〔 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「Lepiota clypeolaria」の詳細全文を読む スポンサード リンク
