''Agaricus dulcidulus'' is a small sized mushroom belonging to the Agaricales order, family Agaricaceae, growing in deciduous woodlands of Europe, but also recorded in North America, North Africa and Asia. The English name is rosy wood mushroom. Despite the tendency of some sources to synonymize it with ''Agaricus semotus'', this is a distinct taxon.〔''Agaricus dulcidulus'' page at Index Fungorum〕 ==Description== Cap 2 to 7 cm, convex-rounded often with inflexed margins at first, then flattens when aging, covered in purple-brown to pinkish dense fibriles that fade in colours towards light grayish-pink from the centre towards margins.〔Saccardo,P.A.(1887)'' Sylloge Fungorum V'': 1007; XIX: 32; XII: 90〕 The gills are free from attachment to the stipe, dense, starting pale gray-brownish when young, then turning dark purple-brown with age, with a lighter crenulated edge. The stipe is cylindrical, 2–5 cm long and 0.4–0.8 cm broad, bulbous or clavated at the base, withish, slightly darkening toward the base in yellow-brownish tints. The ring, remnant of the veil present in young fructifications, is whitish, descendent, thin and fragile. The odor and taste resembles almonds. The spore print is dark brownish. The spores are 4.5–6.0 x 3.5–4.0 µm on average, nonamyloid, and elliptical. The flesh turns slightly in yellow when cut or bruised, sometime with orange tints in stipe. Macrochemical reactions: flesh turns orange and pileus turns yellow in contact with 10% KOH. 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「Agaricus dulcidulus」の詳細全文を読む スポンサード リンク
