Paper: Cetrelia chemotypes are good species

I came across this paper, which is relevant to British field lichenology: https://doi.org/10.1016/j.funbio.2018.11.013 , Mark et al (2019) Lichen chemistry is concordant with multilocus gene genealogy in the genus Cetrelia (Parmeliaceae, Ascomycota) Fungal Biology 123 125-139. Analysing DNA sequence...

Re: Ramalina europaea in Britain

Ramalina europaea like London buses: you wait ages for one – and then two come along at the same time; well a few days latter. I think I now have more material of Ramalina pollinaria s. lat., again appearing to be Ramalina europaea . This time from a Crab Apple branch on the edge of a pasture woodl...

Re: Parmotrema robustum?

Jenny I have only seen this species once, when it looked really different. Partly it was just very very big, but also the soralia are distinct. From the LGBI soralia sparse, rounded and often clustered on small extensions of the incised lobe margins The two pictures I have from Coed Crafnant: 2014-0...

Re: Pale Lecidella elaeochroma?

Juliet I'd like to record whenever I see this morph, which I think is readily identifiable and separable from the shade form. Why couldn't I find any pictures of it on the web? Does it have a special name? I am not aware of any forma name for this morph, there is certainly not one in current use. Th...

Re: Mixtoconidium canariense on Ramalina lacera?

Jenny The 0.2–0.5 mm diameter in that paper refers to the newly discovered apothecia, they refer to the original paper from the conidiomata size, so that is fine. This certainly looks very like it is Mixtoconidium insidens (formerly Mixtoconidium canariense ), which is very good record, Van Der Boom...

Ramalina europaea in Britain

In 2017 a paper came out in the Lichenologist: Gasparyan et al (2017) “Ramalina europaea and R. labiosorediata, two new species of the R. pollinaria group (Ascomycota: Ramalinaceae), and new typifications for Lichen pollinarius and L. squarrosus” https://www.cambridge.org/core/terms. https://doi.org...

Re: Mixtoconidium canariense on Ramalina lacera?

Jenny Looks like a good match other than the conidia sizes. Any sign the "intermixed with simple bacilliform microconidia" I can see some out of focus things that could be these? Given the conidia size disparity it would be best get it checked by someone more expert than me, given it would be new to...

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...

Re: Lecanora hybocarpa an overlooked lichen

Further progress reports on this overlooked but probably common lichen. Knole Park, West Kent: surveyed for the National Trust. This is an ancient deer park in a warm and dry part England. Here Lecanora hybocarpa dominated on the twigs where there was also some Lecanora chlarotera , with some occurr...

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...
