St James Park London and Environment Issues Network

St James Park - home of geese, algae lichens and more..

On 10 October I went to London (via Giggleswick and Lancaster train) for the Environmental Issues Network meeting of Churches Together in Britain and Ireland, which was held at Church House, Westminster.


Arriving 1 hour early, I asked the doorman for a suggestion of where to go for an hour.. He said "Go and see the Queens Swans in St James Park".


So ignoring Westminster Abbey and Methodist Central Hall and the Houses of Parliament, I trotted off to St James Park - which was indeed only 5 minutes away. I passed troupes of Japanese tourists - their guides holding a post high with a flag on it (reminded me of Venice many years ago)


It was a much more relaxing and refreshing way of spending 40 minutes than "doing historic buildings".


Greylag geese

 Assorted ducks. 
And graceful grey squirrels. - how wonderfully they unfold their tails
It was great to see them all so close up. Sadly (or maybe fortunately) I had left my sandwiches at Church House - but even  to opening my bag on the ground  pretending  to get food would draw some of the animals.










I looked at the trunks of several trees  - nearly all London Plane, and also a Lime tree


I found Phaeophyscia orbicularis (the grey one below - it has rhizine underneath, so is held slightly away fro the bark.) , Hyperphyscia adglutinata (the greener one - firmly stuck to the tree) a tiny bit of Xanthoria parietina, and lots of alga



The Phaeophyscia is very common over most of UK, but the Hyperphyscia (form this map below from the NBN Altas) Is more of a southern species but is working its way north.




 Hyperphyscia adglutinata from the NBN Atlas


Books say that both species grow where there is a lot of dust. 

I did not find Lecanora conizoides .

Lichens at Lofthouse - Report of the Moorland Festival Workshop




Fourteen of us including myself met on Sunday 8th October 2017 at Lofthouse Village Hall for the Beginners Lichens Day as part of the Upper Nidderdale Moorland Festival

First we examined the crustose lichens on the walls outside the hall
Candelariella vitellina : This is the yellow lichen on the acid sandstone

In some places, another yellow lichen:- Caloplaca citrina.. 
It was growing on mortar or where water had run over the mortar and then deposited limey material

Here I am sitting in the foreground testing the yellow lichen with KOH - Ah it goes crimson - It must be the Caloplaca.
Ah this one has also turned red - It must be some more Caloplaca


This is Acarosproa fuscata. The thallus is thin  on the capstone of the relatively new wall outside the hall. Later we found it growing half a cm thick  looking like deposited mud on the gritstone wall  on the road up out of the village.(That wall is over 200 years old) 



Porpidia tuberculosa


Here is the Porpidia close up.  The black line round the very edge is called the prothallus. The thallus (main body of the lichen) is arranged in areoles (tiny islands)  with cracks in between. The blue grey marks are soralia - patches where the white skin (cortex) of the fungus allows the contents below to come out - powder made of fungal threads and algae.




We spent time in the hall looking at pictures on a screen and learning these names of parts of a lichen. Then keen not to loose the sunshine, we set off up all of 200m,  up the hill outside the village.. carrying our lovely sandwich lunch that the festival had provided.



Lunch with a view up to Middlesmoor - Later we looked at the trees on the left.






Lunch was relaxing. There were no lichens whatsoever amongst the grass of the grassland - though we did find three waxcap fungi (Hygrocybe punicea, nivalis and a yellow one)  and a Liberty-cap

After lunch we examined the lichen of the trees and the wall







 he green filamentous alga is called Klebsormidium crenulatum.  The darker brown areas - looking a bit like deposited mud are the lichen Acarospora fuscata.  Both grow well where there is lots of reactive nitrogen

Yes there is a farm nearby - but you get this Klebsormidium growing on the wall right to the very tops of these hills.



Acarospora fuscata

And below we have Parmelia saxatilis - called  Crottle or Stony Rag in English






 One person found some Stereocaulon vesuvianum. and we found several species of  Cladonia and





and looked briefly at the welcome to Lofthouse sign 


where there was more Candelariella vitellina  (yellow remember?) and some Rhizocarpon reductum with the fruiting bodies growing in concentric circles 





Then it was back to the village hall







Ah - but we had kept some of the Provisions for tea..





The participants stick some of the larger specimens to their charts with Copydex, and I show them Frank Dobson's book.

Judith writes:-
I went on a short walk in September to explore the village - at the foot of the Côte de Lofthouse (Steep road going up over the moor towards Masham, used in the April 2017 Tour de Yorkshire)


Just to the top right of the metal Lofthouse sign is a yellow green lichen. A closeup follows:


This lichen looks like Rhizocarpon geographicum -
 It is not the same colour as the mint ice cream I bought from the farm below.. We'll check on the day.


This is Meadowbank Farm, at the bottom of the hill. The ice-cream is made on the farm
Hypogymnia- a foloiose lichen
