| Morphology | Sporangia are produced on the surface of the substrate on sporangiophores. The shape of sporangia is spherical, ovoid, pyriform, campanulate, or cylindrical, approximately 10-15 um in size. Sporangia contain numerous spores in chains that are arranged in parallel or irregularly swirl- like rows. Spores (zoospores) are rod shaped (0.4 x 1.2 um) and motile by means of a laterally inserted tuft of flagella. Nonmotile spores are developed in free chains arranged similarly to the zoospores. The organisms are Hyphae of substrate mycelium are 0.2-0.8 um diameter, branched, and septate. True aerial mycelium is not developed. |
