Spots mainly on sheaths but sometimes on leaves in extension, at first small, suborbicular to elliptical, bloody red with a distinct border, later increasing in size or confluent and up to 6 inches in length, dark red on the upper surface, indistinct on the lower. Fruiting amphigenous, effuse, dark grayish brown, velvety, mostly in the center of the spots. Stromata dark brown, composed of a few swollen cells, 15-75 μm wide. Conidiophores not borne on stromata but arise as branches from the external procumbent hyphae, pale olivaceous brown to dark fuligineous, paler towards the apex, slightly irregular in width, intertwined, 1-5 septate, rarely geniculate, often branched, 20- 200 × 3-5 μm, conidial scars conspicuously thickened, up to 1.25 μm wide. Conidia hyaline to olivaceous, cylindric to cylindro-obclavate, straight, 0-5 septate, sometimes constricted at the septa, obtuse at the apex, obconic or short obconically truncate at the base with a thickened hilum, not catenulate, 15-55 × 3-6.5 μm.
