The image presents two photographs of ringless honey mushrooms, showcasing their appearance under regular daylight and when illuminated by a 365 nm ultraviolet (UV-A) blacklight.

**Image Details**

* **Top Photo:**
   + The top photo features a close-up view of the caps of ringless honey mushrooms.
   + The mushrooms are yellowish in color with white or light-colored gills along their edges.
   + The overall appearance is similar to that of other types of mushrooms, with no distinct features visible.
* **Bottom Photo:**
   + The bottom photo shows the same type of mushroom, but illuminated by a 365 nm UV-A blacklight.
   + The caps appear yellowish in color with white or light-colored gills along their edges, similar to the top photo.
   + However, when exposed to UV-A light, the mushrooms emit a bright blue glow, making them stand out against the surrounding environment.

**Key Takeaway**

The image highlights the unique ability of ringless honey mushrooms to absorb and re-emit UV radiation, resulting in a distinctive blue coloration under UV-A illumination. This phenomenon is likely due to the presence of fluorescent pigments or other biochemical compounds within the mushroom's cells. – AI vision

Los sombreros de hongos melíferos sin anillo (Desarmillaria caespitosa) cuando se exponen a la luz diurna regular, así como cuando se iluminan con una luz negra ultravioleta (UV-A) de 365 nm en Lick Creek Park. College Station, Texas, octubre 8, 2024. La imagen presenta dos fotografías de hongos melíferos sin anillo, mostrando su aspecto bajo la luz diurna regular y cuando se ilumina con una luz negra ultravioleta (UV-A) de 365 nm. **Detalles de la imagen** * **Foto superior:** + La foto superior presenta una vista detallada de los sombreros de hongos melíferos sin anillo. + Los hongos tienen un color amarillento con las vellosidades blancas o ligeramente coloreadas a lo largo de sus bordes. + El aspecto general es similar al de otros tipos de hongos, sin características distintivas visibles. * **Foto inferior:** + La foto inferior muestra el mismo tipo de hongo iluminado con una luz negra ultravioleta de 365 nm. + Los sombreros tienen un color amarillento y las vellosidades blancas o ligeramente coloreadas a lo largo de sus bordes, similares a la foto superior. + Sin embargo, cuando se exponen a la luz UV-A, los hongos emiten un brillo azul brillante, destacándose del entorno circundante. **Conclusión principal** La imagen destaca la capacidad única de los hongos melíferos sin anillo para absorber y reemitir radiación UV, dando lugar a una coloración azul distintiva bajo iluminación ultravioleta-A. Este fenómeno se debe probablemente a la presencia de pigmentos fluorescentes u otros compuestos bioquímicos dentro de las células del hongo. – Spanish translation
