I have received a sample with perithecia resembling those of the genus Nitschkia. The asci are many spored and cylindrical rather than clavate in the upper part. The spores are sausage shaped and mostly curved, with the majority measuring between 9.5 and 10um long.
I wonder if there is another genus within the Nitschkiaceae which applies to my sample. Alternatively, is it possible in the genus Coronophora that asci can be cylindrical rather than clavate?
Any help would be much appreciated.
Thank you,
Peter.

Thank you for your reply.
I certainly thought that the fruit bodies strongly resembled those of a non collapsing Nitschkia, but I was unaware of any species with many spored asci.
There are two entries in the Ascofrance database under the synonym Fracchiaea broomeana and their microscopy very closely resembles that for my sample.
Best wishes,
Peter.

Thank you for the references to the literature about this species and the other related genera. I shall have a look at them both.
Best wishes,
Peter.
Thank you for your confirmation of the identification.
I was surprised to find that there was a Nitschkia species with polysporous asci. N. broomeana appears only to have been found twice before in Britain.
Best wishes,
Peter.
