Identifying Sterile Biatora vernalis

Another interesting lichen seen in the two SSSIs surveyed in the upper Elan Valley for NRW was Biatora vernalis . This is a widespread species in the central and western Scottish Highlands but is very rarely recorded south of this. This may partly because it is mainly sterile but I does appear to be...

Bacidina squamellosa

Another lichen I found recently on the Elan Valley survey was Bacidina squamellosa ( Bacidia squamellosa ), new to Radnor. This is probably a widespread oceanic lichen but is still under much recorded. The usually sterile coralloid isidiate thallus looks so very much like Micarea prasina s. lat. tha...

Re: Exciting Stuff in the Elan Valley

The next Oak after the first Calicium hyperelloides tree then produced, not only Opegrapha fumosa , previously recorded from the site, but also a big spread of Tylophoron hibernicum ( Blarneya hibernica ) smothering Lecanactis abietina . This was remarkable, this extreme south western species had on...

Re: Exciting Stuff in the Elan Valley

The next Oak produced small amount of a Calicium with a thick granulose yellowish thallus, I put this down as Calicium lenticulare , previously record from the site. Later a bigger spread of the same lichen, on another tree, brought home the yellowish colour of the thallus: Calicium lenticulare shou...

Exciting Stuff in the Elan Valley

Last month I did a contract survey in the upper Elan valley for Natural Resources Wales. This produced one of the more intense bits of field work I have carried out with two lichens new to Wales and a refund of a species lost to Wales found in succession on three Oaks! The site was Caban Lakeside SS...

Re: PhD Thesis -Alan Fryday

Alan Thanks, dipped in already, look forward to reading this in more depth latter. Note to anyone looking for it, the location in Researchgate is not immediately obvious: go to the Research tab on Alan's page and open it, this has all Alan papers in date order, so you need to scroll down to 1997, wh...

Re: Pale Lecidella elaeochroma?

I have not much experience with this morph but Mark, I think, has mentioned this lichen on the old forum. Yes it seems just to be a pigment deficient morph of Lecidella elaeochroma.

Re: Tuckermanopsis chlorophylla with lichenicolous fungus

Heather

Yes I was ignoring hosts when running through the key, but still could not match it to anything.

Others with more lichenicolous experience than me might have a idea?
