''Panaeolus'' is a genus of small, black-spored, saprotrophic agarics. The word ''Panaeolus'' is Greek for "all variegated", alluding to the spotted gills of the mushrooms produced. == Characteristics == These fungi are mostly dung and grassland species, some of which are quite common in Europe and North America. The gills of ''Panaeolus'' do not deliquesce as do the members of the related genera ''Coprinellus'' and ''Coprinopsis''. Members of ''Panaeolus'' can also be mistaken for ''Psathyrella'', however the latter genus is usually found growing on wood or lignin-enriched soils and has brittle stipes. The gills of these mushrooms are black or grey and have a spotty, speckled or cloudy appearance, caused by the way that the dark spores ripen together in tiny patches on the gill surface; different patches darken at different times. The spores are smooth.〔Meinhard Moser, translated by Simon Plant: ''Keys to Agarics and Boleti'' (Roger Phillips 1983) ISBN 0-9508486-0-3〕 The closely related genus ''Panaeolina'' shares the spotted gills but they are dark brown (not black) and the spores are ornamented. This genus is sometimes treated as part of ''Panaeolus''.〔(Mushroom expert page on ''Panaeolus foenisecii'' ) gives further references using both naming choices.〕 The spores are smooth or roughened, with a germ pore, and all species except for Panaeolus foenisecii have a jet black spore print. 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「Panaeolus」の詳細全文を読む スポンサード リンク
