Gills of dark brown-violet pinkgill mushrooms (Entoloma or Nolanea, Leptonia) when exposed to regular daylight as well as when illuminated by a 365 nm ultraviolet (UV-A) blacklight from Sand Branch Loop Trail in Sam Houston National Forest near Montgomery. Texas

🎞️ #3616-23

The image presents two photographs of the gills of Entoloma or Nolanea mushrooms. The first photograph shows a mushroom with brown-violet pinkgill that is exposed to regular daylight. The second photograph displays the same mushroom illuminated by a 365 nm ultraviolet (UV-A) blacklight from Sand Branch Loop Trail in Sam Houston National Forest near Montgomery, Texas.

The photographs show how the gills of Entoloma or Nolanea mushrooms change color when illuminated by UV light. Under regular daylight conditions, the gills are brown-violet pink. However, when exposed to UV-A radiation at 365 nm wavelength, the color of the gills changes dramatically. The UV light causes the pigments in the gills to fluoresce, resulting in a bright blue or violet glow.

The image is divided into two halves: the top half shows the mushroom with brown-violet pinkgill under regular daylight conditions, and the bottom half shows the same mushroom illuminated by UV-A radiation at 365 nm wavelength. The contrast between the two images highlights the significant change in color that occurs when the mushroom is exposed to UV light.

Overall, this image demonstrates how different wavelengths of light can affect the appearance of Entoloma or Nolanea mushrooms. By using a blacklight with a specific wavelength, such as 365 nm UV-A radiation, it is possible to observe unique features of these mushrooms that are not visible under regular daylight conditions. – AI vision

🇪🇸 Descripción en español / Spanish Description

Las láminas de los hongos Entoloma o Nolanea (Leptonia) de color marrón-violeta rosa cuando se exponen a la luz diurna regular, así como cuando se iluminan con una luz negra ultravioleta (UV-A) de 365 nm desde el Sand Branch Loop Trail en el bosque nacional Sam Houston cerca de Montgomery. Texas, 7 de septiembre de 2024. La imagen presenta dos fotografías de las láminas de los hongos Entoloma o Nolanea. La primera fotografía muestra un hongo con láminas marrón-violeta rosa expuesto a la luz diurna regular. La segunda fotografía muestra el mismo hongo iluminado por una luz negra ultravioleta de 365 nm desde el Sand Branch Loop Trail en el bosque nacional Sam Houston cerca de Montgomery, Texas. Las fotografías muestran cómo las láminas de los hongos Entoloma o Nolanea cambian de color cuando se iluminan con luz UV. Bajo condiciones de luz diurna normal, las láminas son marrón-violeta rosa. Sin embargo, cuando se exponen a la radiación UV-A a una longitud de onda de 365 nm, el color de las láminas cambia drásticamente. La luz UV causa que los pigmentos en las láminas fluoresezcan, resultando en un brillo azul o violeta brillante. La imagen se divide en dos mitades: la mitad superior muestra el hongo con láminas marrón-violeta rosa bajo condiciones de luz diurna normal y la mitad inferior muestra el mismo hongo iluminado con radiación UV-A a 365 nm. El contraste entre las dos imágenes resalta el cambio significativo de color que se produce cuando se expone al hongo a luz UV. En general, esta imagen demuestra cómo diferentes longitudes de onda de luz pueden afectar la apariencia de los hongos Entoloma o Nolanea. Al usar una linterna con una longitud de onda específica, como radiación UV-A de 365 nm, es posible observar características únicas de estos hongos que no son visibles bajo condiciones de luz diurna normal. – Spanish translation
