Re: Possibly Solenopsora holophaea ????

Christine

I agree with Alan definitely not Lecidoma demissum or Psoroma hypnorum and looks very like Solenopsora holophaea, I can not think of what else it could be. It would be obvious if fertile.

Re: Is this Ropalospora viridis?

John

Thanks, I had forgotten that paper, so they are different, but impossible to tell apart morphologically. So until we have hand held DNA scanners, it does not seem realistic to record them

Re: Is this Ropalospora viridis?

Alan It seems to me that BLS/ABLS/IAL needs to fund a sequencing facility that can help resolve problems like this. How about an annual contribution to RBGE to cover staff and material costs? Yes this sort of idea has been mulled over before and Becky, the current BLS president, is keen to get more ...

Re: Is this Ropalospora viridis?

Alan Yes sounds like we definitely need sequencing here to be sure what is going on. I can see that the small, sterile and strongly sorediate morph found in boreal Europe and N. America could be phyologentically separate from a more oceanic Fuscidea lightfootii , but this would still leave us in oce...

Re: Is this Ropalospora viridis?

Looking up Fuscidea pusilla you could call it that, but not sure how you would demarcate from sterile small Fuscidea lightfootii . It certain has not been recorded much in Britain. The Fuscidea account in LBGB2 did not seem to rate Fuscidea pusilla as much more than a morph of Fuscidea lightfootii b...

Re: Is this Ropalospora viridis?

The UV flourescence of Ropalospora viridis is quite week, and is mainly the thallus with the soralia dull in UV. The soralia are also green not yellowish as this material. This looks like sterile Fuscidea lightfootii to me, which has very bright UV flourescence. It is often sterile and frequently oc...

Re: BLS Virtual Identification Meeting

Yes, I will include the False Reindeermosses (Cladonia furcata & Cladonia rangiformis), on which squamules can be difficult to see.

All the best

Re: BLS Virtual Identification Meeting

OK, apologies for the silence, life getting in the way. I think what I could do is a presentation on the Reindeer Mosses and look a likes, and then discuss any problem specimens people have. To this end it would be good to put up pictures/send me pictures of these before hand. I will be away next we...

Re: BLS Virtual Identification Meeting

This is all great, so I will have to start working out how to do it, but Juliet, Caloplaca, ohh dear, I am probably worse than you, but a master class in where we are with this family would be great, if there is someone who has got a grip of it: Paul any thoughts. As you suggested we certainly need ...

BLS Virtual Identification Meeting

An idea for the forum. The BLS has unfortunatly had to cancel further meetings, including the Winter Workshop in March at Cober Hill, which was to be an extended meeting on lichenicolous fungi. So given the COVID situation looks like it is is not ending soon, the BLS are think of doing some virtual ...

Re: Protoparmelia hypotremella in Sussex?

André Aptroot has confirmed that this collection is Protoparmelia hypotremella, so along with Mark's earlier record we have another, if expected lichen for Britain
