Leptosphaeria or Similar in Carex riparia Leaf
Peter Thompson,
16-06-2016 13:06
I have found some pseudothecia embedded in a leaf of Carex riparia. They are quite large, at approximately 0.6mm diameter.
The spores are becoming 7-septate, with two similarly swollen cells in the centre. Their measurements mainly range from 42.5 to 49.75 x 5.0 to 5.25um.
I have attached a photo of the embedded fruit bodies and microphotos of the spores, asci and part of the excipulum.
I can not identify a species with the two swollen central cells in its spores, so I wonder if anyone has any ideas.
Thank you,
With Best Wishes,
Peter.
