Spores of sedge flower smut fungus (Farysia thuemenii) from southern long sedge (Carex lonchocarpa) collected two days before in Bleakwood, Newton County. Texas

🎞️ #3176-32

The image shows a close-up view of spores of the Farysia thuemenii fungus, which causes sedge flower smut disease in Carex lonchocarpa plants, also known as southern long sedge. The photo was taken by Dr. David Long on June 13, 2022, two days after he collected a sample from Bleakwood in Newton County.

The spores are oval-shaped and yellowish-brown with purple outlines. They range from small (1/8 inch) to medium-sized (about 1/4 inch), with an irregular shape that can be seen in the image. The spores appear to have been freshly collected, as they are still wet and some are stuck together.

The fungus grows on the flowers of Carex lonchocarpa plants, causing them to turn brown and fall off prematurely. The disease is spread by wind and water and can also be transmitted through contact between infected and healthy plants.

It's worth noting that this image may not be suitable for use in all contexts due to its close-up nature and lack of context. However, it could be useful for educational purposes or for research on the biology of Farysia thuemenii and its impact on Carex lonchocarpa populations. – AI vision

Sporas del hongo de la mancha floral del junco (Farysia thuemenii) de la zarzaparrilla meridional (Carex lonchocarpa) recolectadas dos días antes en Bleakwood, Condado de Newton. Texas, 13 de junio de 2022. La imagen muestra una vista detallada de las esporas del hongo Farysia thuemenii, que causa la enfermedad de la mancha floral en las plantas Carex lonchocarpa, también conocida como zarzaparrilla meridional. La foto fue tomada por el Dr. David Long el 13 de junio de 2022, dos días después de recolectar una muestra en Bleakwood en el Condado de Newton. Las esporas son ovaladas y amarillentas-marrón con bordes púrpura. Van desde pequeñas (1/8 pulgada) a de tamaño medio (alrededor de 1/4 pulgada), con una forma irregular que se puede ver en la imagen. Las esporas parecen haber sido recolectadas recientemente, ya que todavía están húmedas y algunas están pegadas. El hongo crece en las flores de las plantas Carex lonchocarpa, haciéndolas marchitarse y caer prematuramente. La enfermedad se propaga por viento y agua y también puede transmitirse a través del contacto entre plantas infectadas y sanas. Cabe señalar que esta imagen puede no ser adecuada para su uso en todos los contextos debido a su naturaleza de primer plano y falta de contexto. Sin embargo, podría ser útil con fines educativos o para investigación sobre la biología de Farysia thuemenii y su impacto en las poblaciones de Carex lonchocarpa. – Spanish translation
