Coelomycete on Prunus laurocerasus
Howard Williams, 10-07-2017 16:18
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
