(b) Two-week culture of the mold on oatmeal agar incubated in sunlight, showing hairy, dark brown pycnidia. (c) Young, nonseptate, hyaline conidia and old, septate, brown conidia with longitudinal striations released from the pycnidia. (d) Periodic acid-Schiff-stained histological sections of the mold, showing aggregates of pycnidia. (e and f) Pycnidium with an obvious neck and conidiogenous cells and paraphyses (sterile filaments among conidia) lining the internal wall.
