Lichens and mosses on limestone at Dalehead after Johnny Campbell and Amy-Jane Beer passed by up Penyghent

 Tue 25 March 13:47pm -Johnny Campbell (Second from left) and Amy-Jane Beer  passed by on their way up Penyghent and on up the Pennine way

Fountains Fell Behind them -- turn right...

and set off up Pen y ghent



I crossed over the road (behind me from where I took this photo) and into the field and studied the mosses and lichens on a few rocks of exposed pavement -the rest of the pavement was under soil and mosses.  15 species of moss in no time.  But I struggled to get more than seven lichens on the first few rocks SD843489 713589

Squamarina cartilaginea

The rock I was recording. By the time I took this they had reached the summit.

There was lots of Placynthium nigrum  on the limestone- some fruiting

I moved to some more rocks 20m away SD8435771393
The Placynthium nigrum had a little bit of the parasitic lichen - Toniniopsis verrucarioides

Acarospora glaucocarpa (This is quite close up)
Well that's my guess... but seems pretty similar to A cervina.

A big blob of Rhizocarpon umbilicatum - not many features on it in this photo but a thick thallus and it is turning a little yellow with K . 


So my lichen total was 13.
