fraxinus
Normally a harmless endophyte, but occasionally parasitic. In a study of endophytes in living bark, Kowalski & Kehr (1992) recorded this species also on Acer pseudoplatanus, Fraxinus excelsior, and Quercus robur, but fructifications are unknown from these hosts. Wollenweber (1939) reported a similar anamorph on Rhododendron sp.
