Thanks Neil

Thanks for the introduction to this method Neil, it's been a revelation! And a spectacular one at that. As suggested, most of my 'chlaro' I'm seeing here in coastal NW Wales has turned out to be argentata. These two seem pretty straightforward, but I'm struggling a little with possible hybocarpa spe...

Thanks Neil. That's exciting. There was an orange-brown pigment in the hymenium/epithecium alongside violet and blues which didn't quite match descriptions in the Flora for the others. What shall I do with the specimen - who best to send it to for confirmation one way or the other? I'd normally send...

I was sorting some Megalaria pulverea specimens today, and discovered a puzzling 'bycatch', initially quickly collected as assumed to be part of a large patch of Megalaria. Turns out it wasn't that, and seems similar to Neil's Mycoblastus affinis/alpinus described here. The young apothecia are remin...

Thanks to both of you for this, I'll record it as putative B. hafellneri with caveats, and then hide it away in a box!

Hi, Just wondering if anyone can help here...? I've finally got around to checking a few specimens from Black-a-tor Copse (Dartmoor) from a few years ago. One of these is what I was assuming was going to be Biatoropsis usnearum, but it's on what appears to be U. flammea. Reading the accounts on Fung...

Hi Neil, I've been scratching my head over a Chaenotheca, in every way fitting stemonea, bar the Pd reaction, which appeared Pd- but on closer inspection (dissecting 'scope) there was a slight yellowing of the thallus as you describe here so that's all good. Interestingly though, I'm not getting a P...

Thanks all. That makes sense, the specimen in question was a supposed Lecanora alboflavida that was a bit chewed and with a not overly convincing C+ reaction, so guessing the K/UV neon yellow helps confirm that.

Thanks again, Dave

Hi,

I'm sure the answer to this is already lurking somewhere in this forum, but I can't find it, so.....

Can someone remind me what a strong K/UV yellow reaction is telling me? In this case there was a weak yellowish K reaction before UV turned it into that amazing bright yellow.

Thanks!

Dave

Hi James, fresh from a day of looking at Pyrenula hibernica in its only Welsh site, so yes, you're right with that one I'd say. You can see it doing it's characteristic splitting thing in your first Leptogium pic - the thallus so thick and waxy it doesn't seem to be able to expand at the same rate a...

Thanks Neil. Is it still, as yet, unknown elsewhere in the world beyond GB/Ireland?

I've been looking for this for a while now and most of my suspects turn out to be Cliostomum griffithii in various guises. So, nice to finally find it! This was from lignum on an old snapped branch of a veteran oak pollard, at Hawkcombe in north Exmoor. Actually seems relatively distinctive - the co...
