_Description_: Cap: pinkish tan with slight flush of brown at centre, hygrophanous and drying out buff-coloured or clay-coloured, convex at first then expanding to become plane, but for an obtuse umbo which is retained at the centre. Stem: pale buff, tough, flexible and smooth. Gills: adnexed, pale cream colour or pinkish buff and fairly distant. Flesh: whitish or pinkish tan, smelling of cherry laurel (cyanic). Spore-print: white. Spores: medium sized, hyaline, pip-shaped, smooth, not staining bluish grey when mounted in solutions containing iodine and about 10 × 6 µm in size (9-11 × 5-6 µm). Marginal and facial cystidia: absent. _Habitat_ & _Distribution_: This agaric is very common from May to October on lawns and grass-verges. _General Information_: _M. oreades_ forms well developed fairy-rings, and is easily recognised by its tough nature, pale colours and ability to revive after having been dried. This ability to revive in moist weather even after the fruit-body has been dried by the sun or wind is a character which was used to distinguish members of the genus _Marasmius_. However, this is a very subjective character and since microscopic techniques were introduced and used widely in the study of agarics the genus has been delimited rather more critically. _Marasmius_ is close to _Collybia_ (p. 90), in fact many species appear in one book in one genus and in another book in the second genus; _M. oreades_ itself is not a typical member of the genus. _Marasmius_ seems to be a much more important genus in the tropical and subtropical regions of the world; we have already mentioned how some of the small species of _Marasmius_ in Europe grow only on leaves of a particular plant (see p. 92). _M. androsaceus_ (Fries) Fries (see p. 231) is the horse-hair fungus. _Illustrations_: F 19a; Hvass 81; LH 115; NB 35¹; WD 24¹⁰ (not very good).

Stem: slender, fragile, greyish brown, silky fibrillose-striate and shiny. Gills: almost free, crowded and pale greyish brown when young, but finally flesh coloured. Flesh: brownish and smelling very strongly of meal when cut or broken between the fingers. Spore-print: salmon-pink with flush of cinnamon. Spores: medium sized, fawn under the microscope, star-shaped with 4-6 prominent angles, 9-10 × 7-9 µm, smooth and with no germ-pore. Marginal and facial cystidia: absent. ~Nolanea sericea~ (Mérat) P.
