Hi,
After much crawling around the South Downs and a lot of chalk fragments examined, I think I’ve found Nesothele hymenogonia. The descriptions I’ve read for the perithecia are that they are grey-pruinose, but chalk being what it is, the perithecia just look like they have chalk fragments and dust on them. There is an involucrellum. The spores are muriform sized 25-30 X 12.5-15 um and I found an ascus that had 8 spores. The perithecia has oblong photobiont in it.
Does this look good for Nesothele hymenogonia?
Thank you,
Sylvia
