Lophiostoma on Rhamnus alaterna

Hellohere is a Lophiostoma on Rhamnus alaterna collected by Jean-Paul Priou in Portugal, together with a new Orbilia. Therefore I had a look at it and could not find a name with Holm (Lophiostomaceae of Sweden).
Sp. *(18.5-)20-23(-25) x 7.2-8 µm, 3-5-septate, light ochre-brown (surely so when mature, though no living mature asci seen), very finely & densely punctate, no appendages, dark brown when dead & collapsed.

Hi Zotto and Jean Paul,
I think Lophiostoma quadrinucleatum matches this collection fairly well if it is viewed in the broad sense
accepted by Holm & Holm including five septate ascospores. Such spores are also accepted by Mathiassen (1993) for collections on Salix in Norway.
Best wishes,
Jacques

Hi Jacques
many thanks! The type of L. quadrinucleatum was even on Rhamnus, but Salix, Prunus and Berberis are also cited in Holm & Holm. I only wonder why the puntation of the spore surface is not mentioned. Perhaps too difficult to see?
