sentences:  Maturation is characterized by apical branching (tip splitting) and a dramatic increase of growth speed (up to 200 μm/h at 30 °C), which enables it to cover an 8 cm Petri dish of full medium in about seven days.Sporulation is thought to be induced by nutrient deprivation, leading to contraction at the septa, cytokinesis and subsequent abscission of sporangia which contain up to eight haploid spores.Hyphae are compartmentalized by septa, which in young parts appear as rings that allow transfer of nuclei and in older parts may appear as closed discs.
