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

Some Lecanorales, perhaps it is lichenized?

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