Conidiophores and tissue of anamorph (asexual stage) of crust fungus Hypoxylon rubiginosum growing as soft tiny granules on elm wood under a microscope in KOH, collected on Caney Creek section of Lone Star Hiking Trail in Sam Houston National Forest north from Montgomery. Texas

🎞️ #3386-33

The image shows a microscopic view of Hypoxylon rubiginosum, an ascomycete species that is part of the crust fungus family. The image was captured under a microscope using potassium hydroxide (KOH) solution to highlight the fungal structures.

In the center-left area of the image, there are numerous long, thin, cylindrical structures with rounded tips and smooth surfaces. These structures are likely conidiophores, which are specialized hyphae that produce conidia (spores). The presence of these conidiophores suggests that the fungus is in its asexual stage.

The background of the image appears to be made up of various types of fungal tissue, including mycelium and possibly some plant material. The KOH solution has caused the cell walls of the fungi to dissolve, revealing their internal structures.

Overall, the image provides a detailed view of the microscopic morphology of Hypoxylon rubiginosum, highlighting its characteristic conidiophores and tissue structure. This type of information can be useful for identifying and studying this species further.

*Answer*: The image shows a microscopic view of Hypoxylon rubiginosum, an ascomycete species that is part of the crust fungus family, with numerous long, thin, cylindrical structures (conidiophores) and various types of fungal tissue in its background. – AI vision

🇪🇸 Descripción en español / Spanish Description

Muestra conidióforos y tejido del estadio anamórfico (estadio sexual) de un hongo costra Hypoxylon rubiginosum que crecen como pequeñas esferas blandas en la madera de olmo bajo un microscopio en KOH, recolectado en el tramo de Caney Creek del Sendero de Excursión Lone Star en el Bosque Nacional Sam Houston al norte de Montgomery. Texas, 16 de abril de 2023. La imagen muestra una vista microscópica de Hypoxylon rubiginosum, una especie ascomicética que pertenece a la familia de los hongos costra. La imagen fue capturada bajo un microscopio usando solución de hidróxido potásico (KOH) para resaltar las estructuras fúngicas. En el área central-izquierda de la imagen hay numerosas estructuras cilíndricas largas, delgadas con puntas redondeadas y superficies lisas. Estas estructuras son probablemente conidioporos, que son hifas especializadas que producen conidios (esporas). La presencia de estos conidioporos sugiere que el hongo está en su estadio sexual. El fondo de la imagen parece estar compuesto por varios tipos de tejido fúngico, incluyendo micelio y posiblemente algo de material vegetal. La solución de KOH ha causado que las paredes celulares del hongo se disuelvan, revelando sus estructuras internas. En general, la imagen proporciona una vista detallada de la morfología microscópica de Hypoxylon rubiginosum, destacando sus característicos conidioporos y estructura tisular. Este tipo de información puede ser útil para identificar y estudiar adicionalmente esta especie. *Respuesta*: La imagen muestra una vista microscópica de Hypoxylon rubiginosum, una especie ascomicética que pertenece a la familia de los hongos costra, con numerosas estructuras cilíndricas largas, delgadas (conidioporos) y varios tipos de tejido fúngico en su fondo. – Spanish translation
