Hummingbird Hawkmoth hovering over Red Valerian, with proboscis in a flower
Whitish crustose lichen with white/brownish soredia and dark red apothecia with pale rims
6 or 7 dense clumps of freshly-laid (last night) frogspawn in a Warwickshire garden pond. Surrounded by leaves of Lesser Spearwort, Ranunculus flammula. The jelly has only partially swollen so far
Flat deep-orange lobes with blastidia/soredia
Poorly bit of Xanthoria with black lichenicolous apothecia of Phacothecium varium (previously called Opegrapha physicaria)
White-speckled green thallus of Physcia adscendens, with a galled area showing black ostioles of the immersed perithecia of the lichenicolous fungus
Pinkish-orange knobbly blobs, sporodochia, of Illosporium carneum on Peltigera didactyla thallus
Dry pale brownish-grey lobe of lichen with whitish cobwebby tomentum and patches of blue-grey soredia. Mm scale. Lobe was flattened for the photo, as the top part was curled over.
Section through apothecium of Lecidella stigmatea, with blue-green exciple, brownish epithecium and very pale pinkish-brown hypothecium
Screenshot from another app saying “Revised #lichen I’d. Likely Lecidella scabra (not carpathica), with suppressed soredia, after more reading and re-finding quoted thread. Reference descriptions…” alongside photos of thallus and microscopy sections
Four pieces of bark with crustose lichens, in daylight: Left, Pertusaria hymenea; top, Pertusaia coralliza; right, Pertusaria leioplaca maybe; bottom, Pertusaria pertusa
1-2 cm thalli of greenish-brown-black dry jelly lichen on concrete path
Speckled yellow and purplish-brown woodlouse
Nostoc: just cyanobacterial chains encased in gel. Usually rather formless and floppy
Jelly lichen on mm squared paper
Tiny black spheres mixed in with yellow soredia of Caloplaca citrina
Grey Phaeophyscia orbicularis thallus with black Arthonia phaeophysciae apothecia bursting out
End of a narrow branch with isidia (maybe one soralium with isidiomorphs near the top)
Highly branched lichen lying on dead leaves
Grey branched lichen with a single apothecium (like a tiny satellite dish) at the end of a lobe
Lichen thallus under UV. Apothecial margins and some of the thallus fluorescing pale orange.
Pruinose discs. Pale thallus.
Arrow to dark ostiole of a pycnidium on pinkish-brown lichen thallus
Two grey foliose lichens. Left: Punctelia subrudecta, with rounded soralia on the thallus. Right: Punctelia jeckeri, with abundant marginal soralia and pruinose lobe tips (see next photo). Brown margins to the lobes seem similar on both.
Yellow-green lichen with wrinkles like lava
Flat-lobed grey Phaeophyscia orbicularis over-growing bright yellow minutely-lobed Candelaria concolor
Lichen on tree trunk. Blue-grey lobes with white patterning (pseuodocyphellae) and whitish pom-poms of soredia in soralia. Physcia caesia
Bright green squamules with black spheres (perithecia)
Piece of jelly lichen about 1 mm square, on squared paper. Edge of thallus at the top. NB dark shadow to the left makes it look wider than 1 mm. Dry.
A frosted allotment garden
Top of a gatepost covered in frosty mosses and lichens
Green areolate and white crustose lichen on concrete paving, Warwickshire UK
White crustose lichen on concrete paving, Warwickshire UK
Patchwork of white and greenish lichens on concrete paving slab, Warwickshire, UK

Lecanora horiza greyish thallus with dark red-brown apothecia (c 1 mm diameter) almost falling out of the thallus, with many black spots of the lichenicolous fungus Vouauxiella verrucosa
Daisy-like flowers of Scented Mayweed, with thread-like leaves. The flower heads look very similar to other mayweeds, but these are hollow and sweetly scented.
Tiny yellow branched lichen lobes (that have not changed colour in K). They are often very sorediate, but not in this photo.
Crust lichen, with white pruinise apothecia, with a bright yellow patch where bleach has been applied
Grey-brown foliose lichen on tree bark
Fungus with grey-brown scales on a white cap, with yellowing gills just showing at the edge. Growing in woodchip mulch.
Phone photo (through dissecting microscope) of the tiny foliose lobes of Candelaria concolor (K-). The blue squares are mm.
Bright yellow foliose lichen, Xanthoria parietina, with pink lichenicolous fungus
Thatch with chicken wire over it, with green lichens growing through
