Lichens that may be found growing in Churchyards &c. of City of London' Churches

We are working on a Project to hopefully identify some of the Lichens that may be found growing in Churchyards &c. of City of London' Churches. Including possibly on the Churches themselves? 

We seem to remember seeing some in the small churchyard of St Olave Hart Street: and will be revisiting to see what we can find. See below for the Seething Lane Entrance to the Churchyard:

It occurs to us that we might think about another Project viz. some Lichens of the Canary Wharf area! There have to be some in that Concrete Jungle? Don't there? But we can think about that after finalising the City' Churches Project.

Wild Flowers and Lichens on the Erith Pier

We popped down to Erith to see the Offshore Support Vessel, 'Pegasus': newly arrived and scheduled to be broken up. She was moored beside Tugs, 'Lord Waverley' and 'Buzz': both awaiting similar fates:

On the Sea Wall just downstream of the Pier, we spotted probable Verrucaria ochrostoma viz.

Sweet Woodruffe on Hutchinson's Bank (the LB of Croydon)

We have just realised that the Plant we saw on Hutchinson's Bank (last week) and were unable to identify, is Sweet Woodruffe. We must look out for it again when we return to look for the Glanville Fritilleries.

But we did see Toothwort (on Hutchinson's Bank) for the first time ever!

To Petts Wood and Hawkwood (the LB of Bromley)

Many years have passed since we first visited Petts Wood and Hawkwood: and it had been a few years since we last visited. 

For most of the time the Sun shone and we saw Bees (including Common Carder and Hairy-Footed Flower Bees), Bee-Flies, Butterflies, Hoverflies and Wild Flowers. Also a few Birds including a male Pheasant (first heard, then seen) and a few Jackdaws (in the Soldier's Field) viz.

We find the Cuckooflowers growing in the Local Monad flowering

Totally unexpected. The site where they grow viz. TQ48447706 or thereabouts, was recently mown and we weren't expecting to see any Cuckooflowers, let alone any flowering. But there were seven flowering Plants, the most we have ever seen there, including these:

It's a small area and fairly regularly mown: although not we think, strimmed.

And not many Insects immediately visible! 

We looked for Wild Flowers whilst en- route to the Southern Erith Marsh (or what little there is left it)

Before entering the Southern Erith Marsh via the Waldrist Way' Entrance, we looked around for Wild Flowers on the nearby Road-Side Verges &c. Despite regular mowing &c. and it being a fairly small area, we identified seventeen species (some flowering) viz.

Annual Meadow-Grass

Bristly Oxtongue

Bulbous Buttercup

Common Field-Speedwell

Common Mallow

Common Stork's-Bill

Common Whitlowgrass

Daisy

Dandelion

Dove's-Foot Crane's-Bill

Groundsel

Hairy Bittercress

Red Dead-Nettle

Ribwort Plantain

Sticky Mouse-Ear

Thale Cress

and White Clover

Just inside the Entrance, we saw that the Coltsfoot is still flowering viz.

Xanthoria elegans aka Caloplaca elegans

Xanthoria elegans growing on a local Kerb Stone (in the local Monad).

Although the general appearance initially suggested Xanthoria elegans, on second thoughts, based on the appearance of the lobes giving it a perhaps crustose-placodioid appearance, we wondered, a Caloplaca?

But not a Caloplaca: it being confirmed as Xanthoria elegans.

That being said, the British Lichen Society (BLS) identify Caloplaca elegans as a synonym for Xanthoria elegans.

We understand that in the past it has been recorded as either Xanthoria elegans or Caloplaca eligans, dependent on the observer's perception. 

Interestingly, the synonym persists.

We pay a brief visit to Scadbury Park (the LB of Bromley)

Somewhere to visit when the Butterfly Season hots up: despite time being very limited we managed to see a few Wild Flowers (including a single Bluebell, Ground-Ivy and Lesser Celandine), Common Carder Bees, Hairy-Footed Flower-Bees, Hoverflies and Bee-Flies.

Plus a few Lichens including Parmelia sulcata, Parmotrema perlatum, Physcia adscendens, Punctelia subrudecta, Xanthoria parietina and this assumed Punctelia jeckeri:

viz. C+ red with soredia on the lobe (underside light coloured) margins and brownish (seemingly pruinose) lobe tips. We wonder whether the orange/brown arrangements might be a Trentepohlia species?
