Thanks so much Neil. Yes, there is definitely a thalline margin on these apothecia and the colour on your photo is what I see – I find it quite difficult to get yellow/orange on photos actually the colour I see in reality. The habitat would fit as well – very old tree with damage to the trunk.

Best wishes,

Sylvia

Thank you both, that’s great.

Not a lichen I’m going to come across in Sussex any time soon, but I think a new record for Appleby St Lawrence churchyard. Interesting about the UV result. I only had tiny amounts of thallus to work with as it was from a churchyard headstone, but definitely orangey tinge.

Best wishes,

Sylvia

Thank you Neil, that’s great. Hopefully I’ll also start to see a few more across Sussex now.

All the best,

Sylvia

Thanks Maxine and Mark,

This is the second time I’ve found it, but the first time it was on sandstone and it looked just like it does on bark. Not the case for flint, where it will be very easily overlooked as the thallus was so thin and barely there, as well as being the same colour as flint. Perhaps Cresponea premnea will turn up next!

Thanks,

Sylvia

Looking at the Verrucaria and similar is certainly a challenge. Thanks once again for your in-depth replies they’ll help me get a grip on the little devils.

Best wishes,

Sylvia

That’s great Mark, thank you. I have a few other photos that I have checked, but I can’t see any interascal filaments, so I feel confident about the ID. The presence or not of an involucrellum can still confuse me though and I was uncertain at first.

The churchyard also contained Thelidium incavatum and Thelidium decipiens on a nearby limestone tomb, so almost the ‘quad’. I feel I need to have a look for the fourth one now!

Best wishes,

Sylvia
