Melittosporiella on Salix caprea in Sweden

I found this Propolis-like fungi on dead branches of Salix caprea in central Sweden today and have worked with it this evening. I came to understand by the thick ascus wall and 3-septate spores (~20x3µm) that it is a Melittosporiella and according to Ove E. Erikssons 'Checklist of the non-lichenized ascomycetes of Sweden' M. pulchella might be a common but overlooked species here whith only a few records. But as I have gone through threads here it seems that pulchella is a mediterranean species and M. (Propolis?) angulosa is described from north? Are there any recent studies?

Hi yes, I think that you are correct in your determination of M. angulosa. I'm working on a revision of the genus now and material from Sweden would be good to have. Any chance that you would be able to send some to me?

Re : Melittosporiella on Salix caprea in Sweden
fantastic Johan, please, is it air-dried? If so I can get the fungus in culture and make sequencing a lot easier! I will send you my address in a message. Thank you so much!

I also think it is M. angulosa. Since my homepage still does not work, here my key.

Jason, I air-dried it overnight in room temperature, will post it during the day and hope that you can confirm M. angulosa wich seems to be new for Sweden.
Hans-Otto, thanks for posting the key and confirming M. angulosa!
