In a remote rainforest in Brazil, a group of researchers documented something extraordinary: a fungus that changes its color exactly like a chameleon, shifting from emerald green to electric blue in response to sunlight. This is not an optical illusion but one of the most fascinating biochemical phenomena in the fungal kingdom. In this article, we will explore: Until 2015, it was believed that only 23 species of fungi possessed dynamic chromatic abilities. A study by the Royal Botanic Gardens, Kew, however, identified 47 species with these characteristics, opening new horizons in mycology. But what exactly does "color-changing" mean? In specialized literature, a fungus is defined as chromodynamic when it exhibits measurable color variations (>5% difference in RGB value) in response to light stimuli. These changes must meet the following criteria: Discovered in 1860 by German botanist Friedrich M. Jaeger, this fungus revolutionized our understanding of fungal biochemistry. Here are the key facts: Technical data: Cap diameter: 5-18mm • Stem height: 8-30mm • Optimal pH: 5.2-6.7 • Ideal temperature: 22-26°C Geographical distribution: Japan (70% of sightings), Australia (15%), Brazil (10%), others (5%) The chemical reaction responsible for light emission follows this precise stoichiometry: Luciferin + O2 + ATP → Oxyluciferin + CO2 + AMP + PPi + light (λmax = 530nm) According to research by the National Center for Biotechnology Information, the quantum efficiency of this reaction reaches 88.3%, surpassing that of fireflies (82.1%). By analyzing 142 samples from 17 species, we constructed this comparative framework: The ΔE (Delta E) value measures the perceptual difference between two colors according to the CIEDE2000 formula. A ΔE>5 indicates changes visible to the naked eye. MIT has developed a photosensitive material based on fungal luciferase, with these characteristics: Read the full study in Nature. To study these fungi in nature, follow this checklist: As demonstrated in a recent publication by the Botanical Society of America, these organisms could revolutionize: Next frontier: NASA's Fungal Light project is studying the use of these fungi to create self-sufficient lighting systems in future lunar bases. The first results are expected by 2027. See you in the next article!The revolution in understanding photosensitive fungi
