Black 16-spored perithecia on crust fungus
Marc Detollenaere, 20-10-2022 21:52
Marc DetollenaereDear Forum,

On a non identified crust fungus  (Corticiaceae spec ) on Frangula alnus we found some small black perithecia. 
With the microscope we could identify some asci with dimensions 20x7µ containing 16 rounded spores of about 2.6µ diameter.
Could someone identify this asco?
