**Image Description**

The provided image is a microscopic view of the white rust fungus *Albugo candida*, which infects cruciferous plants such as tansy mustard.

**Key Features**

* The fungal structures appear yellow due to staining with Lugol's iodine solution.
* **Spores**: Oval-shaped, approximately 20-30 micrometers in length.
* **Mycelium**: Thin, branching strands connecting the spores. The mycelium extends downward from the spore mass.

**Coloration**

The image is stained yellow, as Lugol's iodine solution causes fungal cells to absorb and stain blue-black. This contrasts with plant material, which remains colorless.

**Conclusion**

This image provides a detailed view of *Albugo candida*, a common pathogen affecting various cruciferous plants. The staining technique highlights the fungus's cellular structure, revealing its unique morphology and helping researchers understand its behavior in infected plants. – AI vision

Las esporas y el micelio (en Lugol) del hongo de la roya blanca de las crucíferas (Albugo candida) procedente de la mostaza yernia, recogido cerca de Nails Creek Unit of Somerville Lake State Park. Texas, 8 de marzo de 2023. **Descripción de la imagen** La imagen proporcionada es una vista microscópica del hongo de la roya blanca *Albugo candida*, que infecta plantas crucíferas tales como mostaza yernia. **Características clave** * Las estructuras fúngicas aparecen amarillas debido a la tinción con solución de yodo Lugol. * **Es poros**: Ovalados, aproximadamente de 20-30 micrómetros de longitud. * **Micelio**: Hebras delgadas y ramificadas que conectan las esporas. El micelio se extiende hacia abajo desde la masa de esporas. **Coloración** La imagen está teñida de amarillo, ya que la solución de yodo Lugol hace que las células fúngicas absorban y se tiñan de azul-negro. Esto contrasta con el material vegetal, que permanece incoloro. **Conclusión** Esta imagen proporciona una vista detallada de *Albugo candida*, un patógeno común que afecta a varias plantas crucíferas. La técnica de tinción destaca la estructura celular del hongo, revelando su morfología única y ayudando a los investigadores a comprender su comportamiento en las plantas infectadas. – Spanish translation
