I have recently found this on Ivy (Hedera helix) in West Somerset. Using Ecoflora Ihave got some suggestions

I used Ellis and Ellis (In Ecoflora) to try and find likely candidates In order of preference
Proliferodiscus pulveraceus see http://www.dorsetnature.co.uk/pages-fungi/f-113.html
Stictis radiata see http://www.dorsetnature.co.uk/pages-fungi/f-204.html
Lachnum corticale see https://www.inaturalist.org/taxa/707552 ... -corticale

Has anyone any thoughts

Thanks

Hi Mark

It's always worth reading descriptions as well as looking at macro-type photographs.
I suppose I can see the superficial resemblance to Proliferodiscus.
Stictis species are very different - the apothecia are sunk below the surface level.
Lachnum corticale has very different "hairs".

However - and it's a big however - while all the above are ascomycetes, I think you have one of the reduced basidiomycetes there, in fact a member of the Agaricales.
Check out Lachnella alboviolascens, for example here:
http://fungi.myspecies.info/all-fungi/l ... violascens
and here:
https://www.bioimages.org.uk/html/Lachn ... ascens.htm
The occasional mini-island of hairs in the centre of the hymenium is seen quite frequently.

Hope that helps

PS - get a microscope - lots more fun and information ;)
