Cley Churchyard
Lichen 1
Lichen 2
Dry, curled up Capillary Thread-moss (Bryum capillare)
Myrio albescens (All snail grazed)
A Caloplaca sp, with the white thallus of Diplotomma alboatrum to the left
(note the powdery looking apothecia). It’s not clear if the scurfy area below
the Caloplaca is part of that species’ thallus, or possibly something else like a Verrucaria.
Diploicia canescens.
On Lime and Beech
Opegrapha varia
Most likely a Lecanora, but this would require microscopy and chemical tests.
The image on the FSC chart for Churchyard lichens points towards Leconora polytropa
Opegrapha calcarea, with a bit of Diploicia canescens and Myriolecis dispersa agg. at the top
The lichen with the thick black prothallus is mysterious – can’t immediately think of anything similar I have seen.
The others are more familiar – yellow is Candelariella vitellina, and white is Porpidia tuberculosa.
I will have to investigate the mystery one, whereabouts in the churchyard was it?
Tephromela atra
Opegrapha calcarea

Aldborough Church
Haematomma ochroleucum perhaps. Whitish or grey white thallus with a distinctive 'fringed' white prothallus.
Confirmed as Haematomma ochroleucum var porphyria
Lecanora campestris perhaps.
I suspect this is not Lecanora campestris, the thallus of that species is
usually more grey-green with a white fimbriate margin, and the apothecia more even-sized.
A candidate might be Lecanora horiza, but would need microscopy to confirm.
Placopyrenium (Verrucaria) fuscellum
Verrucaria macrostoma f macrostoma
The yellow one is Caloplaca flavescens. A crustose lichen with lobed margins and a whitish centre. Orange apothecia with paler margins.
Confirmed
Caloplaca flavescens, a few apothecia of Lecanora crenulata and
the main species possibly Lecidella stigmatea, but would need microscopy to confirm.
Two species here, my best guess would be Rhizocarpon reductum and Aspicilia calcarea,
but would need chemical test confirmation
Opegrapha calcarea
Lecanora, probably polytropa
Caloplaca flavescens?
