Re : Cosmospora
I'm definitely not an expert, but want to share some knowledge gathered here about a Cosmospora that I am trying to identify. Experts would need to see a longitudinal section of the perithecia (and thickness of wall), if they are growing on another fungus and unfortunately it is almost necessary to grow the anamorph on Potato Dextrose agar at 25Celsius and examine it.
