Ecology
Life cycle and dispersal
In a recent study using a field-based wind tunnel Eldridge & Leys (1999) showed that continual bombardment of X. semiviridis thalli against both the soil surface and physical objects (fallen branches debris etc.) resulted in the breakdown of thalli into small, detached apical fragments that were easily moved by wind. They hypothesise that thallus fragments are likely to move with much higher frequencies than larger, intact thalli, and thereby provide a means of dispersal to new areas.
