Coelomycete on Prunus laurocerasus

Can anyone help with this coelomycete on Cherry Laurel found at the end of June? Ellis & Ellis seem to have nothing like it on either Prunus or plurivorous wood. Details as follows:

Fruitbodies  round to oval, black, slightly roughened, 0.4-0.8mm, sessile to slightly embedded.

Conidia  thick-walled, multiguttulate, pale green to grey-green in water, elliptic-fusoid-limoniform,
9-18.5 x 6.2-8.5 microns. The majority 13-17.5 x 7.5-8.5 microns.

Substrate  thin dead attached twig of Prunus laurocerasus.

Hi,
it resembles Chlostachys ralfsii, the asexual morph of Bionectria ralfsii.
Regards,
Christian

Re : Coelomycete on Prunus laurocerasus
Thanks for this, Christian. I'm sure you're right and my apologies to Ellis & Ellis too who did have it described and illustrated under Nectria ralfsii - which I missed; though in the same wood I have found Bionectria ralfsii in its ascomycetic form on dead Taxus baccata wood.

E&E mention the conidia  as the Myrathecium state, which I can get up on internet Images; but I can't seem to raise your Chlostachys ralfsii. Is this the latest name for this form, or perhaps an older name?

Thanks again,
Howard

you can see several collections of tis specie in the data base of Ascofrance like this by example: http://www.ascofrance.fr/base-de-donnees-fiche/186

All the best,
