Soil fungus

Post by leonardturner »

Image


An exuberant growth of a white fungus on soil prompted this somewhat frustrating exploration which has lasted over several days and many images. In spite of their explosive growth potential, these are fragile organisms and multiple stacks were rather mushy. In some stacks the radial arms could be seen to wave around from one image to the next. I first tried diffused LED lights, and then moved to strobes. Bits of the fungus were moved from the dry mounting surface to a wet paper, and finally to a “tent” composed of the top of a plastic cup with a shooting aperture cut into the bottom, placed on the wet paper, hoping to maintain hydration, humidity, temperature, and avoid any errant wind currents.

Ironically, this was cropped from one of the early images with LED lighting. I believe what I am seeing here is a group of orange conidiophores, perhaps Pencillium or Aspergillus, arising from the transparent fungal hyphae. I would gladly learn from other opinions or thoughts about any of this!

Fascinating image, and an exceptionally difficult subject to photograph. All of those translucent and reflective bits rendered very well.

The upper right corner seems to have the best contrast. What is the field of view? It would be great to isolate the whole subject on a black background.

That's an impressive image of a fleeting subject. I am still struggling with subjects like this.

That would be extremely challenging, given the many influences that cause movements, as you describe. The dang thing might be best done as a wet mount prepared for microscopy.

An excellent result, well worth the effort. I once spent far too much time trying to get a stack of photos of a gyrating Piptocephalis fungus, a frustrating experience!
