Hello,
I found this Genea in Abkhazia (Great Caucasus), Aapsta river valley, in a margin of a way where grew Cornus, Corylus, Carpinus, Acer and Prunus, in a calcareous area, 7th July 2015.
Ascomata were only partly hiden in the soil (visible without raking), measured 1.5-6 mm, were black, covered with small warts (2-3 per mm), with a hole, whitish when cut, not very lobed.
Spores without ornament measure 31-35 x 24-26 micrometers, ornamented with warts of different size and shape - 2-7 micrometers high, 2.7-5 micrometers broad, truncate, often with little projections, sometimes resembling molars.
I excerpted all names mentioned in the article Species diversity of Genea in Europe, but always found some different characters than in my Genea. What do you think?
Thanks, Zuzana
