Gernot FriebesHi,I wanted to share this collection on Rubus idae

Gernot FriebesHi,do you think this collection could be R. ulmari

Looked at Bulgariella pulla but no match.
With many thanks

Hi Tony,
I think this might be a dessicated Exidia that has become overgrown with an olive-green hyphomycete.
Kind regards,
Charles.
Hi ,
It reminds me more Hadrotrichum pyrenaicum, anamorph of Hypoxylon cercidicolum, growing on Fraxinus.
Alain

Alain your suggestion seems spot on to me just from a macro point of view. The Hypoxylon is quite unusual in the way is sits on the substrate and nothing I can find matches this elsewhere. The spores are correct for the conidia state for Hadrotrichum pyrenaicum. Found on a twig on the woodland floor in dark damp mostly Corylus trees. Obviously there is a Fraxinus among these I didn't see. You probably have helped identify a 1st for the UK, with grateful thanks. No records on British Mycol. Soc and one possible record from Scotland earlier this year. That cited the mature state, but probably was H. pyrenaicum if a genuine record.
Added one more image found showing the cross-section of the structure producing perithecia.
So grateful thanks to you and to AscoFrance.
Tony
This is species 506 in my book. There are 27 records in CATE2, mainly from southern England, but not Cornwall. 14 of these are Ainsworth's records, so they should be in the BMS database too.
The conidial state and sexual state of a fungus count as one species, for any where the relationship has been scientifically proven.
One very common example is the ascomycete Rhytisma acerinum, for which the conidial state Melasmia acerina is much more frequently found throughout the year.
With Best Wishes,
Peter.
