FIGURE 2. Morphological features of P. australis. Colonies growing on potato dextrose agar, becoming yellow in colour and emanating white sporangiophores that exhibit positive phototropism that collapse once several centimetres tall (A). The columella is visible at the base of the developing sporangium (B). Eventually the lower surface of the columella collapses inwards (C) to form a mature sporangium (D, F, G, H). Spores are elongated in shape (E, H, I). The outer surface of the sporangium is covered with small spikes (G and H). The spores lack surface ornamentation (H and I). B to D dissecting microscope, E DIC image from a compound microscope, F to I SEM images. Scales bares represent 300 μm B to D, 50 μm E, 100 μm F, 10 μm G, 20 μm H and 5 μm I.
