General Description
A tiny "black dot" found as a pioneer on young Hazel stems on old Hazel bushes in woodland, including abandoned coppices. Generally western, but recently found in eastern England and Scotland so may be spreading. The small black perithecia on silver bark look similar to Eopyrenula sp with pycnidia and microscopic examination is needed to identify this species.
