Bagworm Moth Case
Fen Bedstraw
Prickles on the stem corners & leaf edges.
Ash Bark beetle channels
Branched Bur Reed (Sparganium erectum)
Slender False Brome (Brachypodium sylvaticum) infected with the 'Choke' disease Epichoe sylvaticum
Infected stems will not flower.
It's just possible this is the larva of a fly from the genus Botanophila.
The fly feeds on the young 'male & female' fungal fruit bodies, ingesting the pollinating substances. It then deposits the mixture
on another fungus when it lays its eggs. This pollinates that fungus enabling it to produce spores and also provide food for the
fly larvae.
You can see detritus at either end of the larva and the area around it where it has been browsing.

They can be used as an agent of Gorse Control
Hawthorn Dot (Stigmella crataegella)
Swollen Buds on Hazel caused by the gall mite (Phytoptus avellanae).
'Big Buds'
The gall mites completely destroy the young leaves or female flowers.
The galls open in late (image shows open galls) allowing the mites to leave the gall.
A very special hole in a Hawthorn (Crataegus monogyna) Leaf. Caused by a Feathered Cutter (Incurvaria masculella)
The larvae mine leaves initially and then descend to the ground in a portable case and feeding on dead leaves. The hole is the case.
Many-plumed Moth (Alucita hexadactyla) {Each wing separated into six plumes} Hole in Honeysuckle flower.
The larvae feed in the leaves and buds of of Lonicera Sp and pupate on the ground.
Unknown eggs? on the underside of the leaf.

Yvonne's Comments
They keyed out to
Psathyrella rubiginosa
but
this isn’t on the British list?
I’ve been
through the key a few times and can’t get it to anything else. This group is
notoriously difficult so I can’t really be sure. I have dried the specimens.
Cow Bane (Cicuta virosa)

I used the Malcolm Greaves’ on-line key to identify the Scutellinia
and
it was
S. superba
which describes it well I think !
