Hi there,I have found this small valsoid pyrenomycete growing on dead attached Carpinus twigs. For me, it is very strange for being a member of Valsa, as there are no visible ostioles embedded in a grey stromatic mass. Perithecia are arranged in circles.
Microscopically it has allantoid, hyaline, one celled spores of 8-10x1,8-2,4µm. Asci with a distinct apical apparature staining faintly red in Congo. The fruitbody reminds me on some Wuestneia findings...
Any ideas?
All the best,
björn

Re : Valsa?
Hi Björn
Very strange. Are you sure of Carpinus ?
Any Cystospora on the same twig ?

Re : Valsa?
Hi Alain,
I am not that sure about Carpinus, it can also be Fagus. But I did not see any Cytospora on any twig I had collected.
In all Valsa collections I hadn't ever had such small spores (<10µm).

björn

Re : Valsa?
Valsa ceratosperma is perhaps possible : ascospores 6.5-10 x 2-2,5 µm. It has been seen on Betula, Quercus, Malus...
But beeks are longer .
