Nipstone Rock, Day 2 Afternoon of the British Lichen Society field meeting in Shropshire

Following on from the morning visit to Bog Mine near the Stiperstones of Wed 12 July 2023

We parked at SO35629706 1/2 km south of Bog Mine that we had visited in the morning. Through the gate was a signpost up to Nipstones. 
This is an outlier of the Stiperstones. This area had been planted with conifers in the 1960s, but now a project Back to purple had started returning it to heathland. We met a lady collecting bilberries with a bilberry comber.

This lichen covered post pointed up the hill


There was a lizard at the foot of this post.


And lichens on the post



We examined the lichens on the post.

Then set off up the slope to the Nipstone - in the next monad -  SO35689699
The tor is made of quartzite and is 480 million years old

On the vertical side of this tor we found a very dark Parmelia - it had very few white pseudocyphellae and was much flatter on the rock than is Parmelia omphalodes. It is Parmelia discordans. Is medulla does not turn red with bleach as does that of P omphalodes.

Umbilicaria polyphylla




There was some yellow on the rock

We decided it was probably Xanthoria ucrainica

In some shaded place near the foot of the crag was Lepraria membranacea It has a deifinite edge to the thallus







The summit of Nipstone Rock - with North East Shropshire beyond.
It was pretty windy at my height on the rock - never mind the top

Bilberries






Interesting that the only other places I have seen  Parmelia discordans and Xanthoparmelia mougetii in England was at the same place - near the Stainmore Pass with Les and Sue Knight.  (Seen them in Scotland also).

Will I go out tomorrow?  I have collected so many specimens - if I don't sort them out and read about them they will be wasted.  Perhaps it would be better to stay in the lab and sort them out...

See whether I go or not ...
