Makuru is blue, Makuru is wet. The rain keeps falling, and the forest is full with damp, musty smelling wood. Fungi start fruiting, rotting away trees and leaf litter, like this Beefsteak fungus (Fistulina spiculifera). Known as Numar by aborigines, it fruits on Jarrah (Eucalyptus marginata) trees, producing a slow decay in the wood called ‘pencilling’ or ‘black fleck’.
Fallen leaves, fruits, branches and trees play a crucial role in the ecosystem of the tropical rainforest – they provide the essential nutrients for the typically poor soil and therefore enable new plant growth. Fungi and bacteria act as decomposers of the litter, breaking up the material into smaller pieces for detritivores such as worms, mites and millipedes. The shapes and colours of the fungi are truly amazing: some look like mushrooms while others resemble corals, tongues or sponges, and with their sometimes bright colours they add a certain magic to this already wonderful world.
Most colourful and amazing lifeforms in the wet tropics can be seen on the forest floor, however, they often go unnoticed. But if one keeps an eye open for the little things some truly spectacular gems can be found – and this goes for fungi in particular. They play a vital role for the life on our planet, especially in rainforest where their long thread-like hyphae invade and breakdown the tissues of dead wood and leaf litter, producing nutrients for other plants and animals. On a strenuous hike in the pristine Danum Valley we stumbled upon this beautiful Veiled Lady or Long Net Stinkhorn (Phallus indusiatus), a fungus that can be found in tropical regions around the world. Whenever it is ready to reproduce the fruiting body is grown in an effort to attract insects for the dispersion of the spores. The veiled lady is very short-lived, yet the specimen we found was still fresh regarding the slime covered cap and the undamaged hexagon-tessellated skirt – almost a perfect piece of modern architecture.
