Anamorph: conidiomata pycnidia, numerous, scattered, immersed and visible only as a dark grey discoloration of the host; to 100 µm diam., globose, sometimes distorted due to pressure from vascular bundles of the host. Peridium thin, composed of 2-3 layers of dark brown thick-walled angular cells, covered in a sparse network of brown thick-walled hyphae. Conidiophores absent. Conidiogenous cells formed directly from the inner layer of the pycnidial wall, doliiform, hyaline, not proliferating or with a single annelidic proliferation. Conidia 20-30.5 x 5.5-6.5 µm, cylindrical to cylindric-ellipsoidal or cylindric-ovoid, mostly 3-septate, hyaline, with well-developed guttules that tend to obscure the septa, fairly thick-walled, smooth, without an epispore, gelatinous sheath or appendages. Teleomorph: not known.
