Well, that's my name for it, as I could not find anything to match it during a brief online search. I did come across a paper discussing bryosymbiotic microfungi, listing
Cepahlozia as a host, but there was no named species, nor description. This fungus appears to be present on
Calypogeia fissa too, so would appear not be host-specific. If anyone knows anything about this small but striking fungus I'd love to know. For ref, I encountered it during yesterday's lunchtime 'mundane habitat' search - a ditch between colliery spoil and
Molinia mire (photo) - spot the
Osmunda, the main bryo-elements being
Calypogeia arguta, Pellia epiphylla, Sphagnum fimbriatum and
Dicranella heteromalla.
