Stagonospora paludosa  

Anamorph: conidiomata pycnidia, numerous, scattered, immersed and visible only as a dark grey discoloration of the host; 150-200 µm diam., globose, sometimes distorted due to pressure from vascular bundles of the host, the neck usually hardly developed but occasionally to ca 100 µm in length, the ostiole penetrating via a split in the covering tissues, not easily visible. Peridium thin, composed of 2-3 layers of mid brown thin-walled angular cells, covered in a well-developed network of brown thick-walled hyphae. Conidiophores absent. Conidiogenous cells formed directly from the inner layer of the pycnidial wall, doliiform, hyaline, very thin-walled, not proliferating or with a single annelidic proliferation. Conidia 57-64 x 8.5-9.5 µm [41-67 x 8.5-11 µm fide Sutton 1980], cylindric-ellipsoidal to cylindric-fusiform, mostly 7-septate, hyaline, with well-developed guttules, fairly thick-walled, smooth, without an epispore, gelatinous sheath or appendages.
Teleomorph: not known.
