here 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.

Re:Lophiostoma on Rhamnus alaterna
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

Re:Lophiostoma on Rhamnus alaterna
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?
