Lichens for All Trip -- New species at Craven Bank SD8064

SD86 - 04 - SD8064 - Above Giggleswick School Chapel - Craven Bank Lane Lichens

August 1-31 2022 is "Lichens for All Month - 

A month set up by the BLS to remember the contributions of Frank Dobson to lichenology".  The BLS is encouraging people to hold events during this month.

A small group of four had a lichen walk on Sat 6th August in Yorkshire. - Allan Pentecost, Sue and Les Knight and myself. I took us to some of my previously visited sites in SD86 including these rocks where I had been so thrilled to find Xanthoparmelia conspersa back in 2019.

So first port of call was the gritstone outcrops, scoured by the ice,  just off Craven Bank Lane, Giggleswick, above Giggleswick School. (See my trip to SD86 - 04 - SD8064 in April 2019) -  
(Although the lowest point of our walk at 140m (apart from Settle itself) these are the newest rocks - we will visit today.  Brennand (or Grassington) Grit on top of Pendleton Grit -  The base of the     millstone grit layers - 329-328 million years old. )

Here Allan showed us Aspicilia caesiocinerea, Trapelia placodioides (as well as T coarctata next to it) and Lecanora orosthea and confirmed Candelariella coralliza (round tiny squamules/grains and no fruiting bodies).

We then strode 10 metres south and were into the next monad SD8063 where we recorded most of these species again. plus Lecanora crenulata

Les kindly(?) gave me a piece of  Xanthoria parietina from the wall with an lichenicolous fungus in it with nice apothecia,

There was a solitary hawthorn tree here too that had Arthopyrenia lapponina (= A analepta)

This is the NW corner of SD8063 - I described  SD8063 and the geology of the area in my post at the beginning of 2022 

Back in SD8064 on the gate by the road was some Lecanora polytropa (Allan  thought it might be L varia) then we returned to the car to collect our lunch, crossed the road and had lunch on more rocks in the field above Giggleswick School. Some of the shallow soil in the field was dead from the drought, but most had greened up with the rain the previous few days. 

At lunch  we posed with Sue's early edition Dobson

Using Sue's very old well worn Dobson

Lunch 

Candelariella coralliza

Aspicilia caesiocinerea

Fruiting Porpidia tuberculosa.
We put some KOH on the thallus,
dabbed it off then shone UV light on it.
See the purple colour.

Next place to visit would be Settle, before then going on to a stream flowing over "The Austwick formation" - Silurian rocks  on the road near Henside, c. three miles beyond Langcliffe
