Fungi -- Great Britain -- Identification; Mushrooms -- Identification
_Cap_: width 25-40 mm. _Stem_: width 5-9 mm; length 25-50 mm.
_Description_:
Cap: convex then flattened or with slight umbo, umber-brown with a
greyish cast which becomes accentuated as the cap dries out and
finally becoming silky-shiny; the margin is incurved and striate at
first but on expanding it becomes non-striate with time.
Stem: short, fibrillose, greyish brown, shining and white at the base,
very fragile and often snaps just above the soil-level when collected.
Gills: crowded, adnate and pale greyish brown then pinkish brown.
Flesh: with a strong smell of new meal, brownish becoming paler as it
dries out.
Spore-print: salmon-pink.
Spores: medium sized, smooth, pale fawn under the microscope, angular
almost cubic and 10-13 × 8-9 µm in size.
Marginal and facial cystidia: absent.
_General Information_: _Nolanea staurospora_ is very common amongst
grass, in many habitats such as on heaths, and in woodlands and
copses, but it is particularly common in pastures and on lawns. It is
difficult to separate from close relatives on field-characters,
except for the strong mealy smell; however, it is recognised
immediately by the spore-shape, in fact stauro--means a cross and
spora--spore!

Because of the flattened cap and gill-shape _N. sericea_ (Mérat) P. D.
Orton was first placed in _Entoloma_, but for a long time it was one
of the smallest members of that genus. The European species of
_Nolanea_ have recently been critically analysed, and now that closely
related species to the silky _Nolanea_ have been found, it appears
better placed in _Nolanea_ although it is still found under _Entoloma_
in many books. The Latin word ‘sericeum’ means silky and refers to the
silky cap and stem of this fungus which is a very noticeable feature
when the fungus is collected in the dry state. The common name which
has been given to this fungus also refers to the silky nature of the
fruit-body.

Brown hay-cap
_Cap_: width 12-28 mm. _Stem_: width 3-6 mm; length 40-60 mm.
_Description_:
Cap: semiglobate to convex and hardly expanding even with age, smooth,
expallent, dull cinnamon-brown or dark tan-colour, becoming
clay-colour or pale cinnamon-colour from centre outwards on drying and
so sometimes appearing as if it is zoned.
Stem: slender, fragile, smooth and pale cinnamon-brown, except at apex
where it is dotted with white; it is usually more brownish below.
Gills: adnate, crowded, pale brown and mottled, but becoming more
uniformly umber-brown except for whitish margin.
Flesh: whitish or pale cinnamon colour.
Spore-print: purple-brown.
