Hydnoid corticioid mushroom on a standing dry oak when exposed to regular daylight as well as when illuminated by a 365 nm ultraviolet (UV-A) blacklight near Pole Creek on North Wilderness Trail of Little Lake Creek Wilderness in Sam Houston National Forest north from Montgomery. Texas

🎞️ #3612-03

The image presents a striking comparison between two photographs of a Hydnoid corticioid mushroom growing on a standing dry oak tree, captured under different lighting conditions. The top photograph showcases the mushroom's appearance when exposed to regular daylight, while the bottom one highlights its response to illumination by a 365 nm ultraviolet (UV-A) blacklight.

**Image Description**

* **Background**: A standing dry oak tree serves as the background for both photographs.
* **Mushroom Growth**: The Hydnoid corticioid mushroom is visible on the surface of the oak tree in both images, with its growth pattern and texture clearly defined.
* **Lighting Conditions**:
* **Regular Daylight**: In the top photograph, the mushroom appears to be growing naturally under regular daylight conditions, without any artificial illumination.
* **UV-A Blacklight Illumination**: The bottom photograph features the same mushroom illuminated by a 365 nm UV-A blacklight, which highlights its unique characteristics and responses to different wavelengths of light.

**Key Features**

* **Coloration**: Upon exposure to UV-A light, the mushroom exhibits a distinct blue-green coloration, likely due to the fluorescence properties of certain pigments present in its cellular structure.
* **Texture and Pattern**: The mushroom's growth pattern and texture are well-defined in both photographs, with visible ridges and protrusions on its surface.

**Comparison**

The two photographs provide a fascinating comparison between the natural appearance of the Hydnoid corticioid mushroom under regular daylight conditions and its response to UV-A illumination. The use of UV-A light highlights the mushroom's unique characteristics and potentially reveals new insights into its biology and ecology. – AI vision

Translation:

Hongo corticiamorfo hidnióide en un roble seco erguido cuando está expuesto a la luz diurna regular, así como cuando es iluminado por una luz negra de 365 nm ultravioleta (UV-A) cerca del arroyo Pole en el sendero North Wilderness de Little Lake Creek Wilderness en el bosque nacional Sam Houston al norte de Montgomery. Texas, 31 de agosto de 2024. La imagen presenta una notable comparación entre dos fotografías de un hongo corticiamorfo hidnióide que crece en un roble seco erguido, capturadas bajo diferentes condiciones de iluminación. La fotografía superior muestra el aspecto del hongo cuando está expuesto a la luz diurna regular, mientras que la inferior destaca su respuesta a la iluminación por una luz negra de 365 nm ultravioleta (UV-A).
**Descripción de la imagen**: * **Antecedentes**: Un roble seco erguido sirve de fondo para ambas fotografías.
* **Crecimiento del hongo**: El hongo corticiamorfo hidnióide es visible en la superficie del árbol de roble en ambas imágenes, con su patrón y textura de crecimiento claramente definidos.
* **Condiciones de iluminación**: * **Luz diurna regular**: En la fotografía superior, el hongo parece crecer naturalmente bajo condiciones de luz diurna regular, sin ninguna iluminación artificial.
* **Iluminación con luz negra UV-A**: La fotografía inferior presenta el mismo hongo iluminado por una luz negra de 365 nm UV-A, lo que destaca sus características únicas y respuestas a diferentes longitudes de onda de la luz.
**Características clave**: * **Coloración**: Al ser expuesto a la luz UV-A, el hongo exhibe una distintiva coloración verde azulada, probablemente debido a las propiedades fluorescentes de ciertos pigmentos presentes en su estructura celular.
* **Textura y patrón**: La textura y el patrón del crecimiento del hongo están bien definidos en ambas fotografías, con aristas y protuberancias visibles en la superficie.
**Comparación**: Las dos fotografías muestran una fascinante comparación entre el aspecto natural del hongo corticiamorfo hidnióide bajo condiciones de luz diurna regular y su respuesta a la iluminación con luz UV-A. El uso de la luz UV-A destaca las características únicas del hongo y potencialmente revela nuevos conocimientos sobre su biología y ecología. – Spanish translation
