Hi Paul
I think your fungus is Mattirolia roseovirens

I have compared our specimen with the description by Julia Checa and colleages kindly sent by Enrique. It does appear to be close to Mattirolia roseovirens, but the ascospores are rather smaller and there are some other differences. I will store it as M. roseovirens for the present, hopefully more collections will be made and we can investigate the differences in more detail. The web page has been changed: see
