  • Pyxie Cup lichen (Cladonia pyxidata). The stalked cup structures are fruiting bodies known as podetia. Moss (green) is seen growing at the base of the lichen. This common liken is also called trumpet or horn lichen. Lichens are organisms formed by the symbiotic association of a fungus and a green alga or cyanobacterium. They are able to produce nutrients through photosynthesis by the algal cells.  Cladonia lichen are classified as fruticose lichen due to the presence of erect structures. Magnification: 5x on 35mm camera sensor

  • An optical image of the cross section of a leaf support (petiole). The notch in the structure points up and is believed to be associated with water flow over the leaf structure.  The center of the structure is where the pith cells are located, in a mature leaf the center section would be completely filled with pith cells. This section has been dyed with neutral red and brilliant crystal blue.  This picture of the petiole shows a 3mm wide field of view.  This sample was stained to highlight cell structures.

  • Trinitite, also known as atomsite or Alamogordo glass, is the glassy residue left on the desert floor after the plutonium-based Trinity nuclear bomb test on July 16, 1945, near Alamogordo, New Mexico. The glass is primarily composed of arkosic sand composed of quartz grains and feldspar that was melted by the atomic blast. Trinitite is mildly radioactive but is safe to handle for short periods of time.

  • A species of glow in the dark mushroom, Panellus stipticus. This naturally occurring bio-luminescent mushroom is common in New England forests in the fall. This species lives on partially decayed oak and uses a unique chemical reaction to digest chemicals in the oak that are toxic to other fungi. Part of a series showing the mushroom in visible and bio-luminescent light.
