Pore surface of ochre bracket mushrooms (Trametes ochracea) when exposed to regular daylight as well as when illuminated by a 365 nm ultraviolet (UV-A) blacklight on Sand Branch Loop Trail in Sam Houston National Forest near Montgomery. Texas

🎞️ #3613-16

The image presents a striking contrast between two photographs of the same ochre bracket mushroom (Trametes ochracea) surface, showcasing its response to regular daylight and ultraviolet (UV-A) illumination.

**Daylight Photograph**

* The top photograph captures the pore surface of the mushroom under normal lighting conditions.
* The pores appear as small, rounded depressions on the mushroom's cap.
* They are relatively uniform in size and shape, with a subtle texture that suggests a soft, velvety appearance.
* The overall coloration is a warm, golden brown hue, reminiscent of ochre, which gives the species its common name.

**Ultraviolet (UV-A) Photograph**

* In contrast, the bottom photograph was taken using a 365 nm UV-A blacklight.
* Under this specialized lighting, the mushroom's pores exhibit a vibrant, iridescent glow, with hues ranging from pink to purple.
* The coloration is not uniform across the entire surface, with some areas appearing more intensely colored than others.
* This phenomenon is likely due to the presence of fluorescent pigments within the mushroom's cells, which become visible when exposed to UV-A radiation.

**Comparison and Significance**

* The dramatic difference in appearance between the two photographs highlights the importance of considering the effects of environmental factors on fungal morphology and physiology.
* The ability of certain fungi to fluoresce under UV-A light may have implications for their ecological roles or interactions with other organisms in their environment.
* Overall, this image provides a fascinating glimpse into the hidden world of fungi and their complex relationships with their surroundings. – AI vision

🇪🇸 Descripción en español / Spanish Description

La superficie de los hongos en forma de ménsula de color ocre (Trametes ochracea) cuando están expuestos a la luz diurna regular, así como cuando son iluminados con una luz negra de longitud de onda ultravioleta (UV-A) de 365 nm en el Sendero de la Llanura sinuosa del Bosque Nacional Sam Houston cerca de Montgomery. Texas, 2 de septiembre de 2024. La imagen presenta un contraste sorprendente entre dos fotografías de la misma superficie del hongo en forma de ménsula de color ocre (Trametes ochracea), mostrando su respuesta a la luz diurna regular e iluminación ultravioleta (UV-A).
**Fotografía del día** *La fotografía superior capta la superficie de los poros del hongo en condiciones normales de iluminación. *Los poros aparecen como pequeñas depresiones redondeadas en la tapa del hongo. *Son relativamente uniformes en tamaño y forma, con un textura sutil que sugiere una apariencia suave y velosa. *La coloración general es un tono marrón dorado cálido, reminiscente al ocre, que da a la especie su nombre común. **Fotografía ultravioleta (UV-A)** *En contraste, la fotografía inferior fue tomada usando una luz negra de 365 nm UV-A. *Bajo esta iluminación especializada, los poros del hongo exhiben un brillo iridiscente vibrante, con tonalidades que oscilan entre rosa y púrpura. *La coloración no es uniforme a través de toda la superficie, con algunas áreas que aparecen más intensamente coloreadas que otras. *Este fenómeno probablemente se deba a la presencia de pigmentos fluorescentes dentro de las células del hongo, que se vuelven visibles cuando son expuestas a radiación UV-A.
**Comparación y significado** *La diferencia notable en apariencia entre las dos fotografías subraya la importancia de considerar los efectos de los factores ambientales sobre la morfología y fisiología de los hongos. *La capacidad de ciertos hongos para fluorescer bajo luz UV-A puede tener implicaciones para sus papeles ecológicos o interacciones con otros organismos en su entorno. *En general, esta imagen proporciona un fascinante vistazo al mundo oculto de los hongos y sus complejas relaciones con lo que les rodea. – Spanish translation
