Re: Psoroglaena stigonemoides?

Thanks Neil, and yes moss protomema is the most likely.
Among it I also spotted two more of the same apothecia shown in my 'Sclerococcum not Byssoloma' post from a couple of days ago - no closer to naming them though!

Re: Psoroglaena stigonemoides?

Thanks Mark - you've just confirmed my doubts, and for the same reasons!

Psoroglaena stigonemoides?

Dorset, on a roadside fallen Oak branch - originally identified as Psoroglaena stigonemoides but I wanted to confirm as I've only knowingly come across that once before! w Psoroglaena stigonemoides 231119 022.jpg w Psoroglaena stigonemoides 231119 027 fert.jpg w Psoroglaena stigonemoides 231119 053....

Re: Byssoloma marginatum?

Thank you for your reply and looking at the Sclerococcum species on the fungi.myspecies website the apothecia and spores of mine fit for Sclerococcum parasiticum: https://fungi.myspecies.info/taxonomy/term/4720/descriptions But I can find no indication of a host present for them! The only lichen pre...

Sclerococcum not Byssoloma marginatum

I found these very small black apothecia (0.2 - 0.3 mm) with slightly paler margins on a fallen branch from a 100 year old Oak in Dorset, occurring on the bark as well as on the moss/algae. Asci 8-spored, the spores 3-septate, 13-15 x (3-)4-5 µm, originally hyaline or greenish but becoming brown. Th...

Re: Ramalina with medulla K+ pink-red

Hi Juliet, I'm glad you also found multiple Ramalina's with a K+ red reaction (and reassured that my K+ red wasn't just a localised anomaly) but unfortunately Paul Cannon thought none of the specimens I sent him were Ramalina pusilla. There's definitely something odd going on though! Below is his re...

Re: Ramalina europaea in Britain

Yes, that's very possible - and reminds me of why I've always steered clear of trying to identify R. pollinaria sens lat!

Re: Ramalina with medulla K+ pink-red

Thanks Alain - and the spores from specimen in the last photo (section in K) were 1-septate 10-12(-15) x 4-5(-6) µm

Re: Ramalina with medulla K+ pink-red

Thanks Alain, and I found some more fertile thalli on a thinner twig that would possibly have received more sunlight, images below. There's at least one mature apothecia so I'll check that for spore size. There seems to be a K+ reaction from the cortex as well as the medulla, though the medulla reac...

Re: Ramalina europaea in Britain

Hi Neil, I found this thread this evening when I was trying to sort out my odd Ramalina ?pusilla specimens and their K+ reactions. Haven't had the confidence to try identifying Ramalina pollinaria s.l before but I tried the three below: Q1. Dorset on Oak branch, possibly Ramalina europaea? Soralia +...

Re: Ramalina with medulla K+ pink-red

Success! Four more specimens from a twig and a small branch all with medulla K+ very slowly pink-red and the last was fertile (plus a bonus Tremella). There seems to be quite a variation in thallus shape with some more reminiscent of R. canariensis than R. fastigiata. zz q Ramalina pusilla 2 231115 ...

Re: Ramalina with medulla K+ pink-red

Hello Alain and thank you for your reply. I returned today in the hope of finding more but was unsuccessful - even the lower branches are far out of reach so unfortunately I've no option but to check fallen bits of branches and twigs. There were several rather odd Ramalina fastigiata/canariensis typ...
