Hi all,

I am trying to identify a species of the genus Rutstroemia. The sample was collected in Sicilia in a place with Pistacia terebinthus, Rosa sp. and Rubus sp. I do not know the host, it could be any of this three.

I have not been able to find reports of Rutstroemia on the genus Pistacia in Italy or Sicily, maybe there are reports in the mediterranean area that I do not know. The apothecia are brownish-red, around 1 mm, the asci 116-136 x 9.4-12 um and ascospores (7.4)11.3-13.3(15.5) x (3)4-4.5(5.7) um.

I think it could be Rutstroemia fruticeti, maybe an inmature specimen.

This species has been reported several times on Rubus and has similar morphology. If somebody from the mediterranean area, Italy or Sicily can help me I would be glad?

I add some photographs here to know your opinion.

Luis
