Fungi -- Great Britain -- Identification; Mushrooms -- Identification
Stem: slender, white above a narrow, easily lost ring which is
composed of floccose, ochraceous yellow granules which also clothe the
lower part of the stem.
Gills: adnate, cream-coloured and crowded.
Flesh: yellowish with a strong smell of new-mown hay.
Spore-print: white.
Spores: small to medium sized, hyaline under the microscope, smooth,
ellipsoid, 5-7 × 3-4 µm and becoming blue-grey when mounted in
solutions containing iodine.
Marginal and facial cystidia: absent.
_Habitat_ & _Distribution_: Frequently found amongst grass on heaths,
in hill-pastures and in woodlands from summer to autumn.
_General Information_: This fungus is recognised by the
gill-attachment and the powdery-scurfy cap formed by the breaking up
of an enveloping veil composed of thick-walled, rounded cells, similar
to those on the surface of the stem.
This fungus was formerly placed in the genus _Lepiota_ because of the
ring but the veil in _Cystoderma amianthinum_ is formed in quite a
different way to the ring in the true parasol mushrooms. The gills are
also adnate and not free as in the true species of _Lepiota_ (see p.
112). _C. carcharias_ (Secretan) Fayod is found under similar
conditions, but is white or flesh-coloured. _C. cinnabarinum_
(Secretan) Fayod is also found in short grass and moss, but has a
cinnabar-red, floccose cap and _C. granulosum_ (Fries) Fayod is
yellowish brown with non-amyloid spores and adnexed gills.
Many authorities prefer to connect this small group of closely related
species more to members of the _Tricholomataceae_ (i.e. the family
which contains the Wood Blewits (p. 131), _Mycena_ (p. 68, etc.) than
to the parasol mushrooms--_Lepiota_ (p. 112).

False chanterelle
_Cap_: width 25-70 mm. _Stem_: width 4-7 mm; length 25-50 mm.
_Description_:
Cap: bright orange-yellow or apricot, fleshy, soft, depressed at
centre and with wavy, incurved, slightly downy margin.
Stem: yellow at apex, rich red-brown or orange about the middle and
sometimes dark brown at the very base.
Gills: decurrent, deep orange, thin, crowded, repeatedly forked and
easily separable from the cap-tissue.
Flesh: yellowish, pale in the cap, darker in the stem.
Spore-print: white.
Spores: medium sized, hyaline under the microscope, ellipsoid or
pip-shaped, smooth, 7-8 × 4 µm and red-brown when mounted in solutions
of iodine.
Marginal and facial cystidia: absent.
_Habitat_ & _Distribution_: Common in woodlands, particularly with
pines, and on heaths or in rough hill-pastures.
