These were first identified as fresh specimens of the Verdigris Agaric, Stropharia aeruginosa, the first of this species recorded on these Nature Notes pages.
As
soon as I could see the stem it confirmed it due to a sort of feathery
pattern to it.
It
is a Stropharia: Stropharia caerulea
(=S. cyanea) or Stropharia pseudocynea if it smelled of pepper!).
The
last species smells of pepper and is not included in the Roger's
guide on the Stropharia genus.
Bio
Record of Species Entry for Stropharia
aeruginosa
I wondered
about Stropharia aeruginosa,
as the cap is much brighter blue than you normally see in Stropharia
caerulea or Stropharia
pseudocynea.
But Stropharia aeruginosa
is an uncommon woodland species and your habitat looked like amenity grassland
(there was a board and a straight edge to the grass) which is dead right
for Strophari acaerulea.
Stropharia
aeruginosa
has a persistent, spreading, membranous ring, whereas the other two have
a weak fugacious (=disappearing) ring. It also has white spots on the cap
margin, although these can wash off. If you want to be really certain,
you need to check the cystidia on the gill edge (microscope).

Further photographs by Ray Hamblett were taken that seems to lead to my original ID at least to genus level.
It is not
Clitocybe
odora.
