The sea continues to fall on our heads. It doesn’t feel like just raindrops, but then cryin’s not for me, as the song says. So I got my tiny new camera and went out to photograph the leaf litter in the garden. It’s supposed to be waterproof, and the lens is said to be good for macros. Just perfect for the monsoon, the rotting leaves, and the tiny things that scurry down below, rebuilding the world. These are the millimeter scale engines of the ecology.
The beetle on the wall was half a centimeter long. The lens is good. It does focus stacking, so I spent the morning picking up the basics of how to use that. Now I’ll have to figure out how to store the images. Having twenty or thirty nearly identical shots could fill up my disk rather quickly. I’ll have to delete more images. Once this house keeping is done, I can get to the more interesting subject of trying to identify the mushrooms and insects I saw. I’m an absolute novice, so I’ll be grateful for any help. If you can identify something down to species or genus, let me know.
Monsoon can bring out hidden life in the garden, as I discovered on a walk this weekend. A beginning like this year’s is not routine, but not uncommon either: a couple of days of hard rain followed by a few days of sunshine. On a tree-stump that I have inspected at such times for several years now, I found the familiar bracket mushrooms sprouting (featured photo). Through the next few weeks they will grow into amazing dinner-plate sized bodies. Are they edible? I’ve seen this variety in forests near villages and they are not harvested by locals. In the absence of evidence, I have been cautious and not tried to eat them.
Further on, I found a treasure of a tree which I hadn’t noticed before. Its branches have sprouted mushrooms in this week. The fruiting bodies of mushrooms that we see, and sometimes love to eat, are just the tip of an ecological iceberg. Beneath it all is 90% of the lifecycle, the wonderful web called the mycelium. When they intermingle with the roots of trees, they seem to be symbiotic, exchanging nutrients and signaling molecules with the host. And sometimes they seem to provide a means of communication between plants, even those of different species (A BBC article colourfully names this a wood wide web). It is also possible that the webs of these hidden mycelia determine whether or not a forest supports an invading species of tree.
But these mushrooms that I see on this branch are not the soil growing mushrooms associated with trees which are the staple of forests. Are they among the edible mushrooms native to India which are slowly being identified and marketed? I wish I knew. The wonderful umami taste of mushrooms is widely recognized, and I do not mind adding a couple of new flavours to my food. I was not very surprised to find that they are called ‘vegetarian mutton’ in parts of India as widely separated as Maharashtra and Jharkhand. On this one branch of this single tree, I found three varieties of mushrooms sprouting. Does that mean that the tree is dead, and its decay is being hastened by these saprophytic fungi? Or are these the so-called endophytes, which are symbiotic with the tree? I’m afraid it will take an expert to tell.
Looking at these photos and wondering about them led me to documentary films and other information on a wonderful world which I did not know much about. Apart from these ecological connections, there are new horizons of different kinds. An interesting article told me about the possible industrial uses of the mycelium; among others, that mats of mycelia are being marketed as a alternative to styrofoam in packaging! The next time I inhale the wonderful earthy aroma of cooking mushroom, it will not be just the omelette I’ll be thinking about.
