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, which is quite along way down.

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. Neil
August 8, 2019 at 10:33 am in reply to: Tuckermanopsis chlorophylla with lichenicolous fungus #42190Heather 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?
Neil
Paul Rare I my experience but I have seen them before
Neil
Heather Appears not to be in Hawksworth’s draft keys, so I am stumped, so presumably either not described, described since 2010 or new to the area.
Neil
Juliet I agree that looks very like a parietin free morph of Xanthoria parietina, not a shaded form of normal material. Not something I have not seen before.
Presumably it will be prone to sun burn!

A final update on Lecanora sarcopidoides. On my second visit to Knole Park I found two more locations for this species, so there is a substantial population here. Additional interest added included Lecidea hypoptaand Micarea globulosella, so a very rich lignum assemblage in the end. I also went through my herbarium and found three more
Lecanora sarcopidoidesspecimens miss-named either Lecanora albellulaor Lecanora piniperdawith heavily pruinose apothecia disks and strong KC + yellow reactions, one from Oak lignum in the New Forest, one from Pine bark in the Surrey heaths and one from Oak lignum in Windsor Great Park.

Lecidea hypoptaon Oak lignum, a northern species, rare in the south Neil
Nicola Thanks

As promised I have got back to the Fountains Abbey specimen, and yes it is strongly KC + yellow, so is fairly definitely Lecanora sarcopidoides! Also I have gone and found more. I am currently doing a small job on the section (not very big) of Knole Park owned by the National Trust. This has some nice habitat in ancient deer park with lots of ancient trees and fallen dead wood. As with other parks in regions formerly heavily acidified by air pollution, the lichen assembage of the dead wood and dry bark on the ancient trees is proving to be much better than was thought and something of a recovery appears to have occurred. In this habitat I found
Protoparmelia oleagina, Chaenothecopsis nigra, Microcalicium ahlneri, Chaenotheca stemonea, Chaenotheca hispidulaand Micarea misella, while moist bark on old Beech produced Lecanora sublivescensand Mycoporum antecellensand I also found Cladonia callosain acid grassland. As well as this there was some lovely material of Lecanora sarcopidoideson the sides of two large logs. This had a paler cream thallus compared to the Yorkshire material, but was otherwise similar. The KC + yellow reaction was easy to see in the field, a good way of being sure was to drawn up K placed on the lichen with a tissue and then apply the C to the K solution on the tissue. A strong and bright yellow reaction can be seen. [attachment=4]2019-07-03-10.JPG[/attachment]

Lecanora sarcopidoides, taken using a Lichen Candelaris/iPhone combination in the field. The apothecia disks get blacker as they age and the purina disappears from some but is very clear on younger disks [attachment=2]2019-07-03-15.jpg[/attachment]

Lecanora sarcopidoides, part of a specimen at x40 Finally I had another look at some very scrappy material from Scots Pine in glades in ancient Beech woods in the New Forest, with apothecia with pruinose disks looking very like the young disks on the better specimens of
Lecanora sarcopidoidesand also with similar sized spores. There was not much thallus with these, but I was able to get a KC + yellow reaction from this (while finally destroying the specimen). So this is also probably Lecanora sarcopidoides,although I would like find more developed material. [attachment=0]2018-11-08-11.jpg[/attachment]
PossibleLecanora sarcopidoidesapothecia with Calicium parvum, Scots Pine in bog Wosson’s Hill, New Forest One to look out for elsewhere, so far I have only seen it in quality habitat and it appear to be rare across Europe
Neil
Juliet Looks OK to me, the disk is also visibly pruinose, which is a good field lead in to
Lecanora hybocarpa/ Lecanora sinuosa.Quote:By the way, thanks Neil for the posting of all the Lecanora chlarotera look-alikes. Very worrying!
It is a bit, I am finding
Lecanora hybocarpais often the dominant Lecanora chlaroteragroup species across the south, at least on branches and open habitats Neil
Good news I contacted Felix Schumm and he says that the Caloplaca volumes will also be available as ebooks. Finally I might begin to get to grips with the changes in Caloplaca! Neil
OK, managed to scramble through the German publishers site, using google translate, and purchased and dowloaded the Hyperphyscia, Phaeophyscia, Physcia und Physconia Volume. Very good, there is a key in English, in the ePUB in iBooks on the Mac you can copy out the German text and put in Google translate (a big advantage over hard copy), a huge number of species (this has world wide coverage) with many many pictures. These are mostly herbarium specimens, so some fading in colours, but this is a minor issue considering the coverage. Example pages
Phaeophyscia endophoenicea

Seehttps://www.fungi.org.uk/viewtopic.php?f=16&t=2455https://www.fungi.org.uk/viewtopic.php?f=16&t=2455” class=”bbcode_url”> Also lots of thallus cross sections and spore pictures
Phaeophyscia endococcina
[attachment=0]Untitled 4.png[/attachment] All in all worth the price of the digital download but I could not afford the hard copy
Neil
Rereading Boom & Brand (2008) The Lichenologist 40(6): 465–497 as holiday reading (!), I think this may actually be Lecanora sarcopidoides; this has similar spores and micropycnidia and does look similar in macro characters https://www.verspreidingsatlas.nl/7362https://www.verspreidingsatlas.nl/7362” class=”bbcode_url”> Lecanora sarcopidoides. I will explore further when I get back. All the best

Bob As you say nothing is ever simple with
Cladonia. These are very probably Cladonia diversa, but other species in the group can occur in high quality sites thoughout Britain. I have had Cladonia borealisproved by TLC from the New Forest and here there are also wide cupped Cladonia cocciferas. lat. specimens here that appear to fit in to Cladonia cocciferas. str. as well. The Nordic Lichen Flora V5 gives Cladonia diversaas having cups 2-3 (4)mm across, with fragile micro-squamules on the podetia surface, as opposed to Cladonia cocciferas. str. which has 4-7 (15)mm wide cups, without the with fragile micro-squamules, but it can have larger more bullate squamules. Chemically they are identical, so TLC does not help. So any large cupped Cladonia cocciferas. lat. with cups over 4mm across may be the much less frequent Cladonia cocciferas. str. but there is still the complication of Cladonia borealis, which has cups to 6 (12)mm wide. This is apparent distinguishable, where frequent in Scandinavia, by the more smoothly corticate podetia surface but I have only identified this by TLC. All in all
Cladonia cocciferas. lat. may be good name to use! Neil
Alan Thanks, sound very interesting, I will register.
