Fig. 2. In vitro culture of B. salamandrivorans in TGhL broth at 15 °C. (A)Monocentric thalli predominate, with the rare presence of colonial thalli(black arrow). Sporangia develop discharge tubes (white arrow) to releasezoospores (Scale bar, 100 μm.) (B) Scanning electron microscopic image of a mature sporangium with rhizoids (R), discharge tubes (D), and germ tube formation (arrow) (Scale bar, 10 μm.)
