Hello,I'd like to ask for help with a lichen. In which genus (family) should I start searching? Looking like tiny hysterothecia, spores narrowly fusiform, 5-celled with middle cell widened, hyaline, around 20 um long, with gel sheath. There seems to be some hemiamyloid gel in hymenium (IKI+r, KOH/IKI+b). No color reaction in KOH.
On bark of Picea.
Thank you very much in advance.
Viktorie

Perhaps Opegrapha?
