Small green discs on Ammophila
Marc Detollenaere, 24-03-2023 22:04
Marc DetollenaereDear Forum,

On dead leaves of Ammophila arenaria I found some very small yellow-green discs (100-125µ) with a strong amyloid reaction on IKI. Asci measured 30x12µ and the hyaline spores were 1-septate and contained several small guttules. The paraphyses were multiple septate and capitate.
Any ideas?
Many thanks

Marc

Re : Small green discs on Ammophila
Some Lecanorales, perhaps it is lichenized?

Yes it looks to be lichenized. 
Likely a species of the genus Lecania (Ramalinaceae, Lecanorales)

Re : Small green discs on Ammophila
Thank you for your reply.I'll try to find a key of Lecania and related genera.

Re : Small green discs on Ammophila
I found this on Ammophila in 2017 at Ainsdale, near Liverpool. I consulted my lichen expert at The Liverpool Museum who promoted Lecania cyrtella.

Another colleague has found it in Argyll Scotland also on Ammophila.

Re : Small green discs on Ammophila
A bit more information to support the identification.


My notes and pics were sent to Brian Coppins, Senior Lichenologist at Edinburg Royal Botanic Gardens. His response was -

Yes, I'd be happy to call this Lecania cyrtella. There are several otherwise mainly corticolous lichens that can find their way onto grasses, esp. Bacidina species. They need a keen eye to spot and happenchance of being in the right place at the right time and in decent weather conditions to be able to 'screen' such a habitat. Also, being aware that such a habitat niche can exist!
