About the stamp design: Pictures an existing photograph of bioluminescent mushrooms taken by Taylor F. Lockwood.
Rainbow reflectivity: According to the USPS, these stamps were “produced using a proprietary rainbow holograph material that is highly reflective in white light. The stamps were produced using special techniques to enhance the reflective qualities of the material while maintaining the depth of color and detail of the individual images. The rainbow pattern imparts a sense of movement and light to the stamp pane.”
About the Bioluminescent Life set: Includes 10 designs picturing existing photographs of bioluminescent organisms taken by Dr. Edith Widder, Taylor F. Lockwood, Gail Shumway, and Steve Haddock. The creatures pictured are: deep ocean octopus, midwater jellyfish, deep sea comb jelly, mushroom, firefly, bamboo coral, marine worm, crown jellyfish, a different marine worm, and a sea pen.
First Day City: The First Day of Issue Ceremony was held at Sunrise Theater in Fort Pierce, Florida, not far from the Ocean Research and Conservation Association headquarters (ORCA). The organization’s CEO and Senior Scientist, Dr. Edith Widder, provided photographs for seven of the stamps images and was also in attendance at the First Day of Issue Ceremony.
History the stamp represents: In warmer climates around the world, dozens of varieties of bioluminescent mushrooms light up the dense, dark forest floors.
Of the more than 100,000 known species of mushrooms around the globe, about 80 of them are known to exhibit bioluminescence. While these mushrooms can be found all over the world (including in America), most are found in the tropics – specifically Brazil, Southeast Asia, and Australia.
Different species glow in different ways. Some glow just in the caps or part of the caps, some glow just in the stems, and others glow all over. The majority of mushrooms glow green, but some have been found to glow blue, red, or yellow. While their glow can only be seen at night, most mushrooms glow 24 hours a day.
Over the years, scientists have speculated as to why some species of mushrooms glow. A 2017 study found that some species of mushrooms glow to attract insects that can spread their spores. They also believe the glow could be used to scare away animals that might eat it. The glow could also be how the mushrooms release energy.
Glowing mushrooms are sometimes called foxfire, but the names of other species can be just as colorful. For example, some names include eternal light, bleeding fairy helmet, and even jack-o-lantern mushroom.
