Coelo on Malus

Dear friends,some weeks ago I found some Coelomycetes on a dead branch of Malus still attached to the tree. Conidiomata very tiny and dark orange, erumpent through the bark. Conidia are cylindrical of various length and multiseptate.
I add some pictures. Maybe one of you stumbled on this one by chance and has a guess...
Best regards,
Martin

Re : Coelo on Malus
Hi Martin
I suppose this is an anamorph of the genus Plasia?, connected to Durella s.l. (Xylogramma). I have not enough own observations to give a more clear identification.
Did you measure the conidia?

Re : Coelo on Malus
Hi Zotto,
measuring these conidia will give no satisfying result, the range is too wide: 24-40 x 3.5-5.7 µm. The long ones are slim while the shorter ones are more sturdy. There is also a tendency to fragmentation at the septa.
I will follow your hint with Plasia/Durella atrocyanea?...
Regards

Re : Coelo on Malus
Does someone have Sherwood's paper of 1981: Convergent evolution in discomycetes from bark and wood???

I just looked at the paper of Sherwood on Plasia, and I see that the conidia of P. ramicola (anamorph of Durella atrocyanea) fit quite perfectly yours. But I never saw P. ramicola myself so far, although I have plenty of D. atrocyanea collections.
I attach the paper on Plasia.
Convergent evolution I attach next.
