Mathias HassHi everyone, Found on attached branches of top pa
I have found three species of Microthyriales on needles of pinus sylvestris, and I can't identified it.
Species nº1: Tiriotecios 80-100um. Entire margin. Asci tetrasporic. Spores with lateral cilia.
Species nº2: Tiriotecios 100-170um. Irregular margin, not fimbriate. Asci octosporics. Spores without cilia.
Species nº3: Tiriotecios 100-160um. Irregular margin. Asci octosporics. Spores with cilia on the side and at one end.
Looking at the book of Ellis & Ellis, he mentions three species on Pinus. Comparing with that, I think specie nº2 can be Stomiopeltis pinastri. The nº 1, would be similar to Trichothyrina pinophylla, but with spores ciliated and asci tetrasporic. And Microthyrium pinophyllus similar to nº3 but with cilia also at one end.
What is your opinion?
Thanks, Greetings
