Microscopic images of Liebetanzomyces polymorphus. On rice straw (A–F) sporangia of varying sizes and shapes, like elongate (A), ellipsoid (B), ovoid (C), clavate (E) and globose (F). The zoospore cyst (A–C arrowed) is also visible, highlighting bipolar germination. Sporangiophore of varying length and shape, from short to long (A), sometimes eggcup shaped (C) and constricted (E arrowed) is shown. The sporangia with a papilla (D arrowed) and septum (B, C, D, E starred) are also indicated. Sporangia and thalli of irregular morphology on xylose (G–I) and cellobiose (J–L), including some pseudo-intercalary sporangia (J–L) can be observed. Scale bar: 20 µM.
