Description: This species has the cone-like pycnidia of its lookalike A. polypori (described elsewhere), but differs in the larger size. Usually on trees near old forest sites, never on soft-barked trees such as elder and elm. In Ireland, the species is scattered.

Key Identification Features:

• Like A. polypori but with much larger conical pycnidia (to over 0.5mm diam.)
• On oak and sycamore, never on soft-barked trees.
