Enrique RubioHi to verybody
I have tiny immersed or semi-immersed perithecia growing on apothecia of Bactrospora patellariodes in the Balearic Islands (Spain). The asci are polysporic and the mature spores are olive-brown with one transverse septum (exceptionally two). No conspicuous hamathecium. I think in the Muellerella lichenicola complex, but the spores are narrower than usually given to M. lichenicola st. sensu. Or perhaps a Bellemerella species?
What do you think?
