Setae 160/230x7/8µm. Asci pore coloring blue in Melzer. Sizes a bit diffrent then those I have in my key, but could this be something else?

It's Ok Trichoglossum walteri with spores < 100 µm with 7 septas. Octopartitum having spores also 7 septa average but spores longer > 100 µm and spores more acute. T Hirsutum with 15 septa . T. ariabile same shape as octopartitum but spores > 7 and < 15 septas.

Hello JP,
Thanks for your confirmation. I also looked at another species which was very small. I found similar spores and setae so this is also T Walteri, nevertheless the very different shape.
Regards,
Ralph
