Thanks Paul

Thank you for the reply Paul - I did look at Chaetosphaeria ovoidea but had discounted it as the perithecia appeared to be erumpent rather than superficial. Below is an image of the ascus tip that I hope might help - I tried with both Lugols and K+Lugols to see if there was a blue reaction but appea...

Its been a while since I've looked at microfungi and I'm already struggling! Multiple perithecia in slits in a fallen oak branch, spores hyaline, 3-septate, 17-22 x 5-6 µm. Paraphyses present, asci without croziers. Help appreciated - but am I missing something obvious in Ellis & Ellis? z Q1 190312 ...

Very small perithecia(?) along edges of areoles and under the microscope there appeared to be superficial strands of black hyphae (10 um wide) present. The spores were...

Hi Chris - delighted you've a positive identification for it

Thanks Mark - and looking forward to hearing more about the Pronectria work in due course

Thanks Paul - interesting that Abrothallus species are possibly less host-specific than previously thought. I've come across this one on Melanohalea exasperata twice (SW Ire and Dorset) but unable to submit records with only the genus. Hi Chris - the Irish specimen was sent to Paul Diederich but the...
