Australian Nature

No doubt there is a diverse readership for a book about the geological evolution of Australia. In fact, the last comprehensive text intended for experts was The Geological Evolution of Australia and New Zealand (1968), by D.A. Brown, K.S.W. Campbell and K.A.W. Crook; and nothing of major scope for a lay audience has appeared for a longer time. In the past forty years, of course, the subject has advanced enormously in a general sense, not the least being the revolution in our understanding of the mobility and interactions of the outer shell of the Earth through the processes labelled ‘plate tectonics’. Our specific geological knowledge of Australia has also progressed significantly.

‘A crystal atmosphere reflecting a liquid blue never excelled in purity even by soft azure splendour hung over the old Venetian palaces by the magic brush of Turner, lay on the mountain tops throughout the weekend. Sunshine illumed the crags and played fantastic vagaries of colour amidst the fresh foliage, gleaming in gilded beauty on the outer fringe of fern curtains and throwing into deeper shade the bosky nooks of the laminated cliffs and mossy gorges.’

After rain at cooler times of the year, the bush is full of fungi. Fruit-bodies of mushrooms, truffles, puffballs, morels, slime moulds and other larger fungi spring forth in a great variety of shapes and colours. For select Australian fauna and flora, such as birds, reptiles or orchids, there are comprehensive and richly illustrated field guides, which have sufficient text to assist the user in putting names to species encountered. However, existing guides to Australian fungi cover a rather limited number of species, or lack text. Putting names to the multitude of fungi is therefore rather difficult.

In the old days, it was easy. The eagle was a large bird with sharp talons for gripping and a hooked beak for tearing prey; the swallow was a fast-flying bird that left our shores each winter to seek warmer climes. But since Charles Darwin, we can’t say that anymore, because the very language of such descriptions implies purpose – either will (the swallow somehow knowing, planning, its migration) or design.
